libkse was renamed to libpthread.

Don't run verify directly as that would require the perl script to
have execute permissions. Run "perl verify" instead. Replace all
occurences of the hardcoding of ./verify with $(VERIFY) to allow
it to be overridden as well.

For now, build and install this as libkse instead of libpthread.
This will avoid any accidental use of an experimental library.

Mechanically change all libc_r references to libpthread.

Implement pthread_attr_[gs]etguardsize(). Non-default-size stacks used to
be malloc()ed, but they are now allocated using mmap(), just as the
default-size stacks are. A separate cache of stacks is kept for
non-default-size stacks.

Collaboration with: deischen

Update the verify script.

-pthread -> -lc_r

Add test to detect propagation of cancellation points within libc_r.

Automated regression test harness for libc_r. Existing tests are integrated,
a new test for POSIX semaphores was added, and examples of harness usage are
included.

$Id$ -> $FreeBSD$

Add mutex test program.

Revise test code for sigwait and add test code for sigsuspend.
