* The bulk of the work -- i.e. juggling the software and hardware breakpoints,
watchpoints, and memory reads/writes -- is done in the new class
BreakpointManager.
* For the architectures a few capability macros have to be defined, one
pointing to the software breakpoint instruction opcode. Done for x86.
* Some more simplifications in the user debugger code, made possible by the
recently introduced debugger_changed_condition attribute.

installed team debugger and adjusted the code accordingly. It's not needed yet,
but I intend to add support for software breakpoints and those require a bit of
uninitialization that needs to be synchronized with debugger changes and can't
be done with interrupts disabled.

* Removed unused inner struct State.
* Added work-around for the extremely annoying "fState my be used
uninitialized" warning gcc 4 produces. I'm not aware of any solution that
doesn't generate unnecessary code. :-/

window of the view into the application thread. This solves the
race condition with asynchronous SetViewCursor and deleting the
cursor immediately afterwards for real.
* The ServerApp now requires a reference to the current cursor,
just in case...
* Added TODOs for caching the BView token, it's currently resolved
for every single BView call that talks to the server... not good!

reference counting is maintained correctly in the app_server. While reviewing
this code, I have my doubts that my previous solution for handling pending
SetViewCursor() calls is always working as it is intended.

and added a _kern_unreserve_address_range() as well.
* The runtime loader now reserves the space needed for all its areas first
to make sure there is enough space left for all areas of a single image.
* This also fixes the final part of bug #4008.
* Minor cleanup.

the first part of making the runtime loader behave itself; it should already
make Clockwerk run okay with any number of translators (even if not all of
them will work yet).

* Generalized address checks. The debugger can now also read the commpage.
* Added new syscall _kern_get_thread_cpu_state() to get the CPU state of a
not running thread. Introduced arch_get_thread_debug_cpu_state() for that
purpose, which is only implemented for x86 ATM (uses the new
i386_get_thread_user_iframe()).
* Don't allow a debugger to change a thread's "esp" anymore. That's the esp
register in the kernel. "user_esp" can still be changed.
* Generally set RF (resume flag) in eflags in interrupt handlers, not only
after a instruction breakpoint debug exception. This should prevent
breakpoints from being triggered more than once (e.g. when the breakpoint is
on an instruction that can cause a page fault). I still saw those with bdb
in VMware, but that might be a VMware bug.

needed. I've added MediaPlugin* fields to Reader and Decoder plugin classes
which are set when the PluginManager hands out new instances. This way the
manager knows what plugin created the Decoder or Reader instance in the
Destroy*() methods and can decrease the reference count accordingly. Also added
some FBC stuffing to Decoder and Reader. All media plugins need to be recompiled,
in case anyone has some outside the Haiku tree.

boot device is actually read-only (even if it's using the write overlay).
* Do not create a swap file on a read-only device - this would really be a
stupid use of the write overlay (just saw this happening on an older
machine).
* Made swap_file_{add|delete}() take a const char* path - there was no reason
this was writable, and this also avoids casting away the const when adding
the default swap file.
* Minor cleanup.

have a simple dedicated heap for the kernel debugger with stacked allocation
pools (deleting a pool frees all memory allocated in it). The heap should
eventually be used for all commands that need temporary storage too large for
the stack instead of each using its own static buffer.

- While walking down the cache chain, we keep all upper caches locked.
- When we have to unlock -- when waiting for a busy page or reading a page in
-- we unlock completely, including the address space, and restart
vm_soft_fault().
- Folded fault_get_page() and fault_find_page() into one.
This simplifies and improves things considerably:
- We no longer need dummy pages.
- We no longer need vm_area::no_cache_change.
- #2710 is fixed, since we no longer hold the address space lock while
waiting.
* vm_soft_fault(): When we have found our page, we first check whether a page
is already mapped at the address. If it is already our page, we just change
its protection. If not, we unmap it first. Fixes race conditions when multiple
threads fault at the same address at the same time.
* fault_get_page(): When copying a read-only page from a lower cache, no longer
mark it active, since at least for the fault area it is shadowed from then on.
* vm_set_area_protection(): Fixed potential overflow for in the
vm_translation_map::protect() call.

gcc could apparently assume that the register assigned to the one in the
clobber list would keep its value (as can be observed when disassembling
add_debugger_command_etc()).
Using a dummy output register works around the problem and also avoids the
unnecessary initialization of the register.
Comments explaining the mystery welcome.

the syscall. Anything beyond st_mtim was therefore not filled in. Fixes
the incorrectly shown creation times in Tracker.
* The BStatable::GetStat() solution was not sufficient yet. We still have to
provide the old GetStat() symbol for BNode and BEntry, since those could be
used by old applications/libraries. We also still have to implement the old
GetStat() slots in the derived classes, but don't need to implement it in
the base class (was purely virtual before and is private now).
* The old BStatable::_OhSoStatable1() slot function was not implemented
correctly. Calling the virtual function at the vtable slot obviously results
in an infinite recursion. The correct implementation would make use of the
Perform() method, but Be didn't provide one for BStatable, so we have to use
the old GetStat() method. Fixed#3960.

decisions.

and the kernel read those values from the shared object (if available). In the
runtime loader this should eventually replace the gcc version guessing method
currently used (at least for shared objects built for Haiku). The optional
packages need to be rebuilt first, though.

* Copied ide_adapter.h as ata_adapter.h in attempt to further
separate the two stacks.
* Continued renaming stuff in drivers/bus/ATA.h
* Make all the busses/ata drivers include the new headers,
specifically ata_types.h, ata_adapter.h and bus/ATA.h,
they were all including ide_types and bus/IDE.h still
* Some renaming of global variables for coding style consistency
* Removed the promise driver from the build, it's not used on the
image and I don't believe it compiled even for the old IDE stack.
* There is no more Command Queueing in the new ATA stack, so I
removed the capability indication from the busses/ata drivers
and ata_adapter.h.
The new ATA stack still boots fine on my computer and I proof-read
the diff like two times. Basically, this was a careful search&replace
job only. The only things I am not sure about is renaming some
publishing related strings, but it seems to all work fine.
