using the new _kern_get_timezone() syscall.
* Added an implementation of ftime() based on the above function, this
may fix bug #308.

(defaults to turned off).
To make any use of this, you have to call the __dump_allocated() function
at the point you want to check the leaks.

This allows current VLC to run without the need of exporting one of the
LC_ALL/LC_CTYPE/LANG environment variables (it used to crash without this).

* Added syscalls _kern_set_cpu_enabled() and _kern_cpu_enabled().
* scheduler.c::sRunQueue::tail was not maintained at all; changed sRunQueue to
be a simple thread pointer instead of a struct thread_queue.
* Turns out we're monitoring CPU activity incorrectly when we've got more
than one CPU.
* Renamed the global CPU array from "cpu" to gCPU.

The test application lets run a thread at the highest priority that calls
yield all the time - the system stays responsible when it runs, so it seems
to work fine :)
Changed the malloc implementation to use _kern_thread_yield() instead of
snoozing.
We should think about making this call public, too.

idea for real-time threads. They could completely hog the CPU in this
case. Thanks to Marcus for investigating!

* BEntry::Remove() now uses _kern_remove_dir() for directories.
* Added fd parameter to _kern_remove_dir().
* Fixed LibBeAdapter's _kern_unlink() to only work on files, and
added _kern_remove_dir() for directories.

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.

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.

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. :-/

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.

I wouldn't be surprised, if more wrappers are still missing.

support unsbrk(), and that is actually called quite often in Hoard, resulting
in out of memory quite fast.
We don't shrink the heap (yet), but at least we can reuse the memory that
was freed by Hoard (it doesn't just remove bytes from the end, it will also
free up smaller parts in the middle).

suboptimal (if working at all) -- review is appreciated.

easier to define them for now, since they are used unconditionally e.g.
in the Tracker sources.

but it compiles at least. :-)
* Pulled the architecture specific part out of <posix/setjmp.h> into
<posix/arch/<arch>/arch_setjmp.h>.
* Moved setjmp_save_sigs.c from the x86 specific implementation into a
"generic" sibling directory, since it is reusable (and actually used
by the PPC implementation).
* Added generic/longjmp_return.c containing a function __longjmp_return,
which is invoked at the end of siglongjmp(), resetting the signal mask
and validating the return value. It is used by the PPC implementation,
and should also be used by the x86 implementation, but I'll leave that
to someone who's motivated enough to also test it. :-)

functions from glibc 2.3.2. Adding those one by one is extremely
boring and time-consuming work. We should probably just remove the
math stuff again, add a verbatim copy of the glibc directories, and
shuffle things around afterwards.
* Note that for x86 holds sizeof(long double) == 96. I removed the
generic 128 bit long double functions that were in use before and
added respective 96 bit versions to arch/x86 (or left them out, if
they weren't used). For PPC the System V ABI spec supplement specifies
sizeof(long double) == 128, but I had trouble configuring gcc to
actually use that setting (looks like there simply is no support for
TI mode for PPC 32). So we have to live with sizeof(long double) ==
sizeof(double) == 64 for the time being.

x86 the Haiku image still builds, so it is apparently not used. I
guess it would be best to abandon our posix_math.o completely and
use the glibc math implementations instead.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15446 a95241bf-73f2-0310-859d-f6bbb57e9c96
added a generic implementation using atomic_test_and_set().

glibc 2.3.2, which seems to be the version used in other places,
though I also found older files.

system happy for the time being. We need real setjmp()/longjmp()
implementations for PPC eventually, though.

and no longer in src/system/Jamfile.

we might miss some wrappers for some ieee754 functions (to check)
hope nothing is broken
