libroot: Implemented pthread barriers

This is an implementation of pthread barriers pursuant to the relevant specification.

Barriers are essentially a special case of conditional variables,
such that all threads waiting on one are woken up when the number of
waiters reaches a number provided at the initialization of the barrier.
In view of that, this implementation mimics the implementation of pthread_cond,
except it is more specialized and self-contained.

fork(): Follow-up fix to 17b2a3cfc.

* Ingo rightly noticed that the defer_signals counter is reinitialized on
thread's user area creation. Setting the flag THREAD_CREATION_FLAG_DEFER_SIGNALS
indeed gives the expected behavior, deferring signals until undefer_signals() is
called in the child thread. Thanks for the review and fix suggestion.
* Added a simple test showing the values of the defer_signals counter after fork().

This commit replaces the placeholder implementation of sbrk(), which

Use libstdc++, libsupc++ and libgcc from gcc_syslibs.

from the gcc_syslibs build feature for everything except x86_gcc2.
* Use libgcc_s.so from the gcc_syslibs build feature for everything but
x86_gcc2 (which still carries libgcc as part of libroot.so).
* Drop filtering of libgcc objects for libroot, as that is no longer
necessary since we're only using libgcc-as-single-object for libroot
with x86_gcc2, where the filtered object file doesn't exist. Should
the objects that used to be filtered cause any problems as part of
libgcc_s.so, we can always filter them as part of the gcc build.
* Use libsupc++.so from the gcc_syslibs build feature for everything but
x86_gcc2.
* Adjust all Jamfiles accordingly.
* Deactivate building of faked libstdc++.so for non-x86-gcc2. For
x86_gcc2, we still build libstdc++.so from the sources in the Haiku

More work towards hybrid support

* All packaging architecture dependent variables do now have a
respective suffix and are set up for each configured packaging

are still only set up for the primary architecture.
For convenience TARGET_PACKAGING_ARCH, TARGET_ARCH, TARGET_LIBSUPC++,
and TARGET_LIBSTDC++ are set to the respective values for the primary
packaging architecture by default.
* Introduce a set of MultiArch* rules to help with building targets for
multiple packaging architectures. Generally the respective targets are
(additionally) gristed with the packaging architecture. For libraries
the additional grist is usually omitted for the primary architecture
(e.g. libroot.so and <x86>libroot.so for x86_gcc2/x86 hybrid), so that
Jamfiles for targets built only for the primary architecture don't
need to be changed.
* Add multi-arch build support for all targets needed for the stage 1

Some more work on the signal code:
* get_signal_stack() checked the wrong sig_action field (index is signal-1), also,
it had an off-by-one error in the stack range check.
* factored out a restart_syscall() function to avoid code duplication
* arch_setup_signal_frame() relied on the fact that vregs and the signal stack code
is a multiple of 4 bytes in size.
* Fixed sigaction(): it did return the error code directly instead of setting errno.
* signal() actually had a work-around for the broken sigaction()...
* Replaced the sig_func_t typedef with a sighandler_t typedef - this is non-standard
anyway, but now we're at least compatible with the GNU world instead of introducing
our own solution (BSD seems to use sig_t here, BTW).
* Removed now unused sigval structure from the header; it should be added again as
soon as we start supporting it.
* SA_RESETHAND and SA_ONESHOT are the same thing; the former did not work before.
* Made the non-standard SA_* flags refer to the standard ones instead of the other
way around.
* Added a test application for various signal features - works fine under Haiku,
tested also under Linux and BeOS (the latter fails as it does not support SA_RESTART).
More tests should be added, though.
* Cleanup.

* Removing bonnie in favor of bonnie++-1.03d

BTW: I've added bonnie++ as it is. That is, I just realized that some
unnecessary directory/files (like debian) could have been removed.
They shouldn't harm ;-)

Small test for mprotect().

* Added simple test app for readdir() to see how it fills out the dirent
and the private DIR parts.

* Adding xsi semaphore test unit
* Moving common functions and macros used in realtime_sem_test1
to a shared header as they are probably going to be used for other test unit

Test program to reproduce bug #2562.

* Sean C. Farley made me aware that some of the possible solutions to clear
the environment would crash on Haiku. Added a small test application that
just checks every one of those.
* Fixed env locking (in userland, you better check against B_INTERRUPTED).
* Made our code safe against an environ of NULL.
* There is now an additional sManagedEnviron that points to the environment
our code actually managed; whenever an application overrides environ, we'll
get aware of it with the next *env() function invocation, and will handle
it adequately.
* Added non-POSIX clearenv() function.

Small test program triggering a self-deadlock in the memory allocator
when a signal handler that itself uses the allocator is invoked while
the thread originally was in the allocator.

Test for setjmp() that demonstrates why it isn't a good idea to
manipulate the stack pointer as we do.

Tests for POSIX Realtime semaphores. Unfortunately they reveal that the
semantics of fork()ing with unnamed semaphores on other platforms is
different from what I thought it was.

* Added a small app that's able to truncate files - for testing purposes
only.

* A simple test that shows that our string compare functions inherited
by NewOS are all broken. This is the actual reason for bug #724.

Added small setpgid() test.

Some more work on the signal code:
* get_signal_stack() checked the wrong sig_action field (index is signal-1), also,
it had an off-by-one error in the stack range check.
* factored out a restart_syscall() function to avoid code duplication
* arch_setup_signal_frame() relied on the fact that vregs and the signal stack code
is a multiple of 4 bytes in size.
* Fixed sigaction(): it did return the error code directly instead of setting errno.
* signal() actually had a work-around for the broken sigaction()...
* Replaced the sig_func_t typedef with a sighandler_t typedef - this is non-standard
anyway, but now we're at least compatible with the GNU world instead of introducing
our own solution (BSD seems to use sig_t here, BTW).
* Removed now unused sigval structure from the header; it should be added again as
soon as we start supporting it.
* SA_RESETHAND and SA_ONESHOT are the same thing; the former did not work before.
* Made the non-standard SA_* flags refer to the standard ones instead of the other
way around.
* Added a test application for various signal features - works fine under Haiku,
tested also under Linux and BeOS (the latter fails as it does not support SA_RESTART).
More tests should be added, though.
* Cleanup.

Test to verify that the runtime loader semaphore is not initialized
after fork().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21885 a95241bf-73f2-0310-859d-f6bbb57e9c96

added some tests from posixtestsuite-1.5.1, these ones fail on Haiku

* Added sigsetjmp_test to Jamfile.
* Fixed Jamfile (was set to only support libbe_test).
* Fixed warnings.

Renamed the tests/kernel/core directory like the main directory tests/system/kernel
and adapted all Jamfiles.
