eabc04d472 Adjust the syscall stub macros to be consistent in their meaning. In
particular:
SYSCALL() makes a syscall, with errno handling, and continues execution
directly after the macro in the non-error case.
RSYSCALL() is just like SYSCALL(), but returns after success.
Both SYSCALL(name) and RSYSCALL(name) export  "__sys_name" as a strong
symbol, with "_name" and "name" as weak aliases.
PSEUDO() is just like RSYSCALL(), but skipping the "name" weak alias.  It
still does "__sys_name" and "_name".

Change i386 to add errno handling to PSEUDO.  The same for amd64 and
sparc64, with appear to have copied the behavior.
ia64 was correct (as was alpha).  Just remove some apparently unused
variants of the macros. (untested!)
I believe powerpc is correct.
Fix arm to not export "name" from the PSEUDO case.  Remove apparently
extra unused variants.  (untested!)

The errno problem manifested on i386/amd64/sparc64 by having "PSEUDO"
classified syscalls return without setting errno.  eg: "addr = mmap()"
could return with "addr" = 22 instead of setting errno to 22 and
returning -1.

31489a9a26 Use the RET macro.
For setjmp() and longjmp(), put the signal mask where it's supposed to be,
instead of in the space reserved for fp regs.
