failed to take into account that the library contains wrappers for read()
and write() that calls __libc_read() and __libc_write(). This incorrectly
causes normal read() and write() operations to be retried if aborted by a
signal.
Instead of making __libc_read() and __libc_write() retry if aborted by a
signal, add new functions __libc_safe_read() and __libc_safe_write() that
retries operation after a signal. Change reads from manager pipe and
writes to manager pipe to use __libc_safe_read() and __libc_safe_write().
thread attributes for the main thread.
Add emulation of native threads (libc_r) method of getting the current
thread attributes (pthread_attr_get_np()) and adjust emulation of native
threads pthread_attr_getstackaddr() to return bottom of stack instead of
top of stack.
Correct emulation of native threads pthread_mutexattr_settype() when
selecting recursive mutexes. Previously, the argument conversion before
calling the linuxthreads version of pthread_mutexattr_setattr() ended up
selecting errorcheck mutexes instead of recursive mutexes.
the communication over the pthread manager pipe a little more robust by
retrying after EINTR failures. Without this fix, linuxthreads based
binaries that run fine on FreeBSD 4 starts crashing in mysterious ways
on FreeBSD 6.

- Block cancel signal while creating new thread to avoid losing
the signal.
- Terminate the process with _exit(1) if it's unsafe to continue
calling atexit functions and destructors.
