MFC: 1.8 (don't get stuck if a signal interrupts us during wait4)

MFC: For libc_r, do not create both weak and strong symbols of the same

Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),

just use _foo() <-- foo(). In the case of a libpthread that doesn't do call conversion (such as linuxthreads and our upcoming libpthread), this is adequate. In the case of libc_r, we still need three names, which are now _thread_sys_foo() <-- _foo() <-- foo(). Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(), nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo(). Remove all internal libc usage of: creat(), pause(), sleep(), system(), tcdrain(), wait(), and waitpid(). Make thread cancellation fully POSIX-compliant. Suggested by: deischen

Add three-tier symbol naming in support of POSIX thread cancellation

points. For library functions, the pattern is __sleep() <-- _libc_sleep() <-- sleep(). The arrows represent weak aliases. For system calls, the pattern is _read() <-- _libc_read() <-- read().

by W.Richard Ste vens. EINTR handling suggested by bde@freebsd.org). Code cleanup: 1. Add missing return type. 2. Replace 'union wait' by int. 3. Use Posix-style signal handling instead of signal(). 4. Use fork() instead of deprecated vfork(). 5. Block signals before fork()'ing, instead of after. 6. Return -1 if fork() fails, instead of 0. 7. Add EINTR handling for waitpid() call. Also add claim of Posix conformance to man page.
