Changed so that when __REENTRANT is defined, cerror calls __errno()
...
for the address of a variable used to store the error number instead
of writing to the global errno.
In a multi-threaded program, __errno() will return a pointer to a
thread-specific variable.

Added new macros:

SYSCALL_NOERROR(x): Like SYSCALL except that "x" is a syscall
that can never fail.
RSYSCALL_NOERROR(x): Like RSYSCALL except that "x" is a syscall

These macros simply call SYSCALL / RSYSCALL, and serve as placeholders
until an optimized implementation is done.
