'RELENG_4_0_0_RELEASE'.

Undo the ill-conceived breakage of the previous commit and really fix:

For libc_r renamed syscalls, correct symbol naming from _thread_sys_foo() <-- _foo() to _thread_sys_foo() <-- _foo() <-- foo(). This is necessary for system calls which libc_r doesn't define foo(). Some weak symbols such as poll() are defined twice. From what I understand, depending on one weak symbol or the other to be used is a bad idea. All such weak symbols defined in the libc_r-specific code should therefore be made strong (non-weak?). Simplify PSEUDO() to not define any weak symbols, since they aren't ever needed. alpha/SYS.h: Correct reversed usage of WEAK_ALIAS(), which has reversed arguments from __weak_reference(). Also, fix reversal of symbols, so that syscall foo() is a weak alias for _foo(). Add WEAK_ALIAS() call to PRSYSCALL(), which unlike the i386 version of PRSYSCALL(), is not defined in terms of PSYSCALL(). Make PSEUDO() equivalent to the i386 version.

For syscalls that are renamed to _thread_sys_foo, create a weak alias

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

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().
