34b3b26b3b Merged branch haiku/branches/developer/bonefish/optimization revision
23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
  it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
  the assembly handler which now uses a jump table to call C functions
  handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
  interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
  rare events (signals, user debug enabling/disabling) on the
  common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
  retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
  the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
  common functions (currently memcpy() only). They are used in the
  kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
  member offsets in assembly code.

Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
  (caused by refactoring and introduction of "call" debugger command).

fcfbb8aa6c libprefs.so uses the private _klock_node_() syscall, and even loops until it
returns success - since this stub always returned failure, this prevented all
apps using that library (like Gobe Productive) from running.
It now calls the Haiku equivalent _kern_lock_node(), and Gobe now runs fine!
This closes bug #562.

636bfc08ae * Renamed fs/vfs_select.cpp to wait_for_objects.cpp and got rid of
vfs_select.h, respectively moved most of it into the new kernel
  private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
  work pretty much like poll(), but also for semaphores, ports, and
  threads.
* Removed the "ref" parameter from notify_select_events() and the
  select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
  is no longer needed. The FS interface select() hook still has it,
  though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
  pair, now. Added respective functions for semaphores, ports, and
  threads.

74c0424a43 * Added a mechanism to retrieve a BMessage with eventual error descriptions
for _kern_load_image().
* Added KMessage to the runtime_loader (a bit hacky, though) - it will use
  it to deliver the above mentioned functionality.
* load_dependencies() did return the wrong status code in case a library
  was missing; now it returns B_MISSING_LIBRARY.
* load_dependencies() will now try to load all dependencies when a report
  message is requested; therefore, all missing libraries are listed.
* Renamed uspace_program_args to user_space_program_args.
* The kernel filled in various members of the user_space_program_args structure
  unsafely, ie. was not using user_memcpy().
* Renamed some local variables in team.c to better fit our style guide (ie.
  uargs to userArgs).
* Changed Tracker to use the new _kern_load_image() variant on Haiku to retrieve
  and report all missing libraries. This fixes bug #1324.
* Adapted kernel_cpp.cpp to the runtime loader as well; the latter will now
  compile with _LOADER_MODE defined.

* Some more cleanup.

44b5d72b5a Added new functions to the debugger API:
{set,clear}_debugger_{break,watch}point(), allowing to set/clear break
and watchpoints for the calling team. When a break/watchpoint is hit,
the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.

We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.

1cbf8f4b3c initial support for a commpage, which is a chunk of memory in high kernel space with user readonly permissions.
The first use is to let the kernel decide what the preferred syscall mechanism is at boot time and copy the
appropriate user space code there. Can be used for routines the kernel can decide best how to use (memcpy, some
timing routines, etc).

ea4ff0f689 is_computer_on() lives again as a true syscall.
Replaced the _kern_null syscall with _kern_is_computer_on.
is_computer_on_fire is a bit harder, since it returns a float from kernelland, which
at the moment isn't supported in haiku.

262e0a636b We use the same strategy for computing the system time as on x86 now.
The time base conversion factor is the 32 bit value
  2^32 * 1000000 / time base frequency,
so the system time can be computed by
  system time = time base * conversion factor / 2^32.
The expression in system_time() looks more complicated now, but is
actually much faster (factor 2.5 on my Mac mini). I'm positively
surprised, how good the assembly looks, that GCC 4 generates. There's
not that much potential for optimization by hand-coding the function.

34a9556215 Made our glue code compatible to BeOS again. IOW executables compiled for Haiku will
now run under BeOS as well (as long as they don't use any functions that are not
available under R5).
The solution is a bit messy, but we have to live with it :-)
The runtime loader now patches the __gRuntimeLoader symbol in libroot.so to point
to its exported structure instead of passing it to the init functions as an
argument.

e55e1a0e66 Implemented the PPC specific RTC support. We search for an "rtc"
device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

09bb4e9ac5 The real_time_data structure contains an architecture specific
substructure now (that's the only member actually). The system time
offset is therefore accessed via architecture specific accessor
functions.
Note, that this commit breaks the PPC build. Since I want to rename at
least one file I've already changed, I can't avoid that.

6e040d83ea Added __swap_{float,double} for PPC. They are probably horribly
suboptimal (if working at all) -- review is appreciated.

d85fe0ec25 Compatibility functions. Actually not needed for PPC Haiku, but it's
easier to define them for now, since they are used unconditionally e.g.
in the Tracker sources.

c729b01278 The <arch_config.h> header is needed in <syscalls.h>, since we're using
the atomic functions related macros.

353d20c0c5 * libroot and the runtime loader are no longer built with kernel rules.
* New rule Ld, analogously to KernelLd.
* Added StaticLibrary parameter for supplying additional objects.

589f2f5a7f Made it a bit clearer how settings parsing works in the kernel, so that Ingo
hopefully doesn't see the need to "fix" it anymore :)

10fbb5f7fd The driver settings in the boot loader overwrote the settings for later kernel use;
they could not be parsed again by the kernel, and thus, safemode was not working
anymore (as it was queried by the SMP stuff).

758b1d0e05 Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
  declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
  explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
  something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
  'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
  is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
  Otherwise the an inner class with that name is considered as friend.
  gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

571bb2b2a6 Simplified the x86 syscall interface a bit. We no longer pass a pointer
to the parameters nor the number of parameters; the kernel is able to
get both without problems.

The syscall functions in libroot (_kern_*()) are now self-contained
(they don't "jmp" to separate code anymore), which at least
theoretically allows gdb to print a stack trace with the syscall
function on the top when a thread is currently performing a syscall.
Practically it doesn't work yet, though, since those functions are
frameless (i.e. create no stack frame) which needs special support
I haven't implemented yet.

that into account as well (they were reporting an error even though everything
went fine).

794df3bf25 This removes the inline assembly code for find_thread
from OS.h, sorry for triggering a complete rebuild.
To avoid doing a syscall for find_thread(0), the assembly
version is now in libroot. For BeOS R5 compatibility, 
_kfind_thread_ is retained. This will fix some compile 
problems, and provides a cleaner OS.h for future Haiku
versions.

null byte, and add junk as arguments. Thanks to Korli for testing.

43ed6aa0db The "shebang" handler is supposed to parse arguments, too - we now do that.
Also, when the line is too long, E2BIG is returned.
Thanks to Korli who pointed me to this: http://homepages.cwi.nl/~aeb/std/shebang/

be22452f3b Apparently, both load_image() and exec*() support running scripts. We do that
now as well.
Also, both functions will now test if the executable exists and is valid; that
way, load_image()/exec*() can catch many errors without having to create a new
team (or erase the current one - an exec*("my invalid app") might now return
with an error).
The runtime linker now exports a function to test executables that is aware
of the search paths, and will also check user permissions upfront.

183dee22cb Unlike R5, receive_data() could return an error code under Haiku - this
can now only happen if the thread is killed.
_user_receive_data() will now longer pass B_CAN_INTERRUPT to receive_data(),
but B_KILL_CAN_INTERRUPT - this should fix the problem Stefano experienced
with this function, even if I couldn't reproduce it.
