Clean up syscall generation in libc by removing HIDDEN_SYSCALLS

and treating (almost) all system calls the same way:

	__sys_foo - actual syscall
	foo, _foo - weak definitions to __sys_foo

Change PSEUDO syscalls (currently only _exit and _getlogin) to
be __sys_foo (T) and _foo (W).

Add $FreeBSD$ to a few files to satisfy commitprep.
