Repo copy libpthreads to libkse.

This introduces the WITHOUT_LIBKSE nob, and changes WITHOUT_LIBPTHREADS to mean with neither threading libs. Approved by: re(kensmith)

Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it.

Warning, after symbol versioning is enabled, going back is not easy (use WITHOUT_SYMVER at your own risk). Change the default thread library to libthr. There most likely still needs to be a version bump for at least the thread libraries. If necessary, this will happen later.

Use C comments since we now preprocess these files with CPP.

Export offsets of thread signal pending set and signal mask for debugger.

Add compatibility symbol maps. libpthread (.so.1 and .so.2)

2006-03-13T00:59:51Z

used LIBTHREAD_1_0 as its version definition, but now needs to define its symbols in the same namespace used by libc. The compatibility hooks allows you to use libraries and binaries built and linked to libpthread before libc was built with symbol versioning. The shims can be removed if libpthread is given a version bump. Reviewed by: davidxu

Add usleep to the map files.

Use a generic way to back threads out of wait queues when handling

signals instead of having more intricate knowledge of thread state within signal handling. Simplify signal code because of above (by David Xu). Use macros for libpthread usage of pthread_cleanup_push() and pthread_cleanup_pop(). This removes some instances of malloc() and free() from the semaphore and pthread_once() implementations. When single threaded and forking(), make sure that the current thread's signal mask is inherited by the forked thread. Use private mutexes for libc and libpthread. Signals are deferred while threads hold private mutexes. This fix also breaks www/linuxpluginwrapper; a patch that fixes it is at http://people.freebsd.org/~deischen/kse/linuxpluginwrapper.diff Fix race condition in condition variables where handling a signal (pthread_kill() or kill()) may not see a wakeup (pthread_cond_signal() or pthread_cond_broadcast()).

Add a wrapper for execve(). The exec'd process must be started with

the signal mask and pending signals of the calling thread. These are stored in userland in libpthread. There is a small race condition in this patch which could cause problems if a signal arrives after setting the (kernel) signal mask and before exec'ing. The thread's set of pending signals also are not yet installed in the exec'd process. Both of these will be corrected with the addition of a special syscall.
