Nested syscall restarts (interrupted syscall in a signal handler)
aren't tested yet.

* Added syscall restart support for connect(), accept(), send(), recv(),
which are implemented via ioctl()s. The actual restart support is done
in the net stack driver's ioctl() hook. Lower layers need to correctly
deal with socket timeouts, though, for which the stack module provides
support functions.
* TCPEndpoint::_WaitForEstablished() does abort now when an error
occurred earlier, so that trying to connect to an unused port fails
immediately, as it should.
* Fixed and refactored TCP connection reset handling. The new
TCPEndpoint::_HandleReset() does the job. Got rid of
TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
correctly and could even be reused when trying to connect again (as
was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.

* Implemented automatic syscall restarts:
- A syscall can indicate that it has been interrupted and can be
restarted by setting a respective bit in thread::flags. It can
store parameters it wants to be preserved for the restart in
thread::syscall_restart::parameters. Another thread::flags bit
indicates whether it has been restarted.
- handle_signals() clears the restart flag, if the handled signal
has a handler function installed and SA_RESTART is not set. Another
thread flag (THREAD_FLAGS_DONT_RESTART_SYSCALL) can prevent syscalls
from being restarted, even if they could be (not used yet, but we
might want to use it in resume_thread(), so that we stay
behaviorally compatible with BeOS).
- The architecture specific syscall handler restarts the syscall, if
the restart flag is set. Implemented for x86 only.
- Added some support functions in the private <syscall_restart.h> to
simplify the syscall restart code in the syscalls.
- Adjusted all syscalls that can potentially be restarted accordingly.
- _user_ioctl() sets new thread flag THREAD_FLAGS_IOCTL_SYSCALL while
calling the underlying FS's/driver's hook, so that syscall restarts
can also be supported there.
* thread_at_kernel_exit() invokes handle_signals() in a loop now, as
long as the latter indicates that the thread shall be suspended, so
that after waking up signals received in the meantime will be handled
before the thread returns to userland. Adjusted handle_signals()
accordingly -- when encountering a suspending signal we don't check
for further signals.
* Fixed sigsuspend(): Suspending the thread and rescheduling doesn't
result in the correct behavior. Instead we employ a temporary
condition variable and interruptably wait on it. The POSIX test
suite test passes, now.
* Made the switch_sem[_etc]() behavior on interruption consistent.
Depending on when the signal arrived (before the call or when already
waiting) the first semaphore would or wouldn't be released. Now we
consistently release it.
* Refactored _user_{read,write}[v]() syscalls. Use a common function for
either pair. The iovec version doesn't fail anymore, if anything could
be read/written at all. It also checks whether a complete vector
could be read/written, so that we won't skip data, if the underlying
FS/driver couldn't read/write more ATM.
* Some refactoring in the x86 syscall handler: The int 99 and sysenter
handlers use a common subroutine to avoid code duplication.

The return value of Inode::WaitForRequest() is status_t not bool. So the
method would always fail when it actually succeeded. This affected reads
from pipes which didn't have data. The bug was hidded since VFS code
mostly checks error codes only against < B_OK, so that such a read would
be treated as 0 byte read.

BeOS R5's glue code incorrectly calls _thread_do_exit_notification()
when main() returns, while Haiku does that in exit(). Therefore when
terminating this way the exit hooks were called twice for executables
built under BeOS R5. This caused e.g. NetPositive or the R5 svn to
crash on exit (our network code actually uses those hooks).
Fixes bug #1742.

* Tracing of allocations, reallocations and frees
* Leak checking infrastructure to dump allocations
The leak checking code records the team and thread id when an allocation is
made as well as stores the originally requested size. It also adds the
"allocations" debugger command that can dump all current allocations (usually
a huge list) or filter by either a team or thread id. This way it's easily
possible to find leftover allocations of no more active teams/threads.
Combined with the tracing support one might be able to track down the time and
reason of an allocation and possibly find the corresponding leak if it is one.
Note that kernel heap leak checking has to be enabled manually by setting the
KERNEL_HEAP_LEAK_CHECK define to 1.

and pages are now kept in lists as well. This allows to return free pages once
a bin does not need them anymore. Partially filled pages are kept in a sorted
linked list so that allocation will always happen on the fullest page - this
favours having full pages and makes it more likely lightly used pages will get
completely empty so they can be returned. Generally this now goes more in the
direction of a slab allocator.
The allocation logic has been extracted, so a heap is now simply attachable to
a region of memory. This allows for multiple heaps and for dynamic growing. In
case the allocator runs out of free pages, an asynchronous growing thread is
notified to create a new area and attach a new heap to it.
By default the kernel heap is now set to 16MB and grows by 8MB each time all
heaps run full.
This should solve quite a few issues, like certain bins just claiming all pages
so that even if there is free space nothing can be allocated. Also it obviously
does aways with filling the heap page by page until it overgrows.
I think this is now a well performing and scalable allocator we can live with
for quite some time. It is well tested under emulation and real hardware and
performs as expected. If problems come up there is an extensive sanity checker
that can be enabled by PARANOID_VALIDATION that covers most aspects of the
allocator. For normal operation this is not necessary though and is therefore
disabled by default.

some absolute path was not enough to always recognize a library as
already loaded. This fixes problems with Perl where loading an add-on

not use a single static variable to synchronize CPUs at two points. In an
environment where CPUs do not really run concurently (in emulation or with
logical processors) it would be possible for CPUs to get trapped in the first
synchronization while another CPU might just do its thing and change the
sync variable again. These CPUs would then never leave the first loop as the
exit condition has already passed again. The key is to use two different sync
variables like it is done in early kernel initialization. As I didn't manage
to trigger this code though I am not sure if this is gonna work.

This is not safe when already freed memory is overwritten. But since we also
store the next pointer of the freelist in there, overwriting would break the
freelist and cause a crash in that case. This gives a drastic performance
boost when freelists grow during use and especially when opening and closing
a lot of programs.

stuff for the ExtendedPartitionAddOn. If I understand correctly, from the
point of view of the Disk Device API, ExtendedPartitionAddOn is a disk system
which supports child partitions and is analogous to PartitionMapAddOn. The
type string for the supported child partitions is probably wrong, since I
used "Intel Logical Partition".... In fact, the types currently returned by
PartitionMapAddOn are not as intended either. We will have to think of how
we want this particular feature to work.

When specified it desigantes that the interrupt handler should not lock the
vector with a spinlock when executing the installed interrupt handlers. This
is necessary to allow the same interrupt vector to be handled in parallel on
different CPUs. And it is required for the CPU halt to work synchronously when
there is more than one AP CPU. Though the acquire_spinlock() should cause IPIs
to be processed, only this fixed the SMP_MSG_FLAG_SYNC problem for me.
Not locking is safe as long as it is guaranteed that no interrupt handler is
registered or removed while the interrupt handler is running. We can guarantee
this for the SMP interrupt handlers we install in arch_smp_init() as they are
never uninstalled. Probably this flag should be made private though.

conditions (I guess we should introduce and use a DescriptorGetter class).
* Cleaned up fcntl.h, moved the BSD extensions S_IREAD and S_IWRITE to
sys/stat.h where they belong, and added the missing S_IEXEC to them.
* Added some more comments.

confirmation after sending off the startup IPIs. We simply moved on and setup
the temporary stack address for the next CPU to be started. With this it was
possible that the trampoline code did not manage to load the address before
we overwrote it. So for configurations with more than two CPUs it was possible
that two CPUs were setup to the same kernel stack which could have caused all
sorts of things - most likely a tripple fault and a reboot. On real hardware
this seems very unlikely but it was easily reproducible with QEMU and -smp >2.
We now use the shared trampoline stack to implement a notification mechanism.
The trampoline code will clear the stack location variable once it has loaded
everything it needs from the trampoline stack. On the other side
smp_boot_other_cpus() will wait for this variable to be cleared after it sent
the startup IPIs so that it knows when it can safely move on and overwrite the
area to boot the next CPU.

we now always only use the primary ring buffer.
* Removed secondary ring buffer allocation and member fields.
* Increased size of the primary ring buffer to 65536 bytes.
* The bytes per row register is computed differently for 9xx chips.
* On G33, the overlay does not need a physical address anymore, so we
don't pass B_APERTURE_NEED_PHYSICAL to the allocation anymore for that
device.
* intel_free_memory() accidently added the aperture base to the allocation
and would therefore never free any memory.
* INTEL_RING_BUFFER_SIZE_MASK was shifted one bit to the right, didn't
cause any harm with our buffer sizes, yet, though.
* With these changes, the driver runs stable on a G33 chipset (I have not
yet tested the hardware cursor, though, it might need some work, too).
The only known issue left is that overlay flickers a bit if its buffer
is partially backed up by reserved and allocated memory.

* Fixed binding/unbinding pages in the Intel GART driver; I accidently shifted
the page offset twice.

* The kernel now opens up to 8 debugger modules (and puts them into an array;
maybe we'll want to switch to a doubly linked list when there is the need).

* The other one was that an inputrc file at /etc was ignored, the bash would

* Now uses the AGP GART module for memory management. This greatly simplifies
the memory handling, and memory is now actually allocated on demand,
instead of a fixed size (stolen memory is not freed, though).
* The Intel GART module should now also work with older chipsets.
* No longer remove the GTT size from the stolen memory; this appears to have
been a mistake in the X driver. Not sure about the BIOS popup yet.
* The AGP module (in combination with the Intel GART module) is now mandatory
to use the Intel driver.
* Removed now superfluous settings (like memory size). Only enabling/disabling
the hardware cursor is still supported.

* Aperture::fFirstMemory was not initialized.
* Added some more debug output.
* BindMemory()'s vertical to physical address translation didn't work correctly.

Intel chips will come later).
* Renamed agp bus manager to agp_gart to reflect its new functionality (even

was a race condition when more than one CPU would enter the debugger at the
same time (or rather before one CPU could stop all the others). We now use the
inDebugger variable to tell if someone is already in the debugger and then
only process inter CPU messages and retry entering the debugger.
Since sending the synchronous broadcast most of the time hung over here with
SMP enabled I removed the synchronous flag and added a simple spin to give the
other CPUs a chance to process the halt request. Added comments that explain
the reasons and a ToDo to revert to synchronous delivery once we fixed the
problem. The kernel debugger is now usable on my quad core.

A thread that just missed a semaphore and put itself into the sems notify
queue could be enqueued into the run queue by release_sem_etc() of another
CPU before the CPU running the thread had a chance to reschedule it. Therefore
there is a timeframe where a thread can be running on one CPU and already be
in the run queue again. In this case no other CPU may schedule this thread
because then it would overwrite the threads' CPU pointer which kills the rest
of the scheduler logic, smp_get_current_cpu() and everything that depends on
that (like the kernel debugger). The more CPUs you have the easier this could
happen, up to the point where it was always triggered during boot on my quad
core system. The system would freeze and you could not enter the kernel
debugger, because two CPUs thought they were the same and disabled each other
through SMP communication. This makes booting my system stable and might fix
the occasional hang on boot for other SMP systems with only 2 CPUs/cores.
I've put a ToDo comment that details this above the workaround. Maybe we
should fix this in another way. Reviews, comments and suggestions welcome ;-)
