8d2887f884 fcntl.h: O_SEARCH was missing for powerpc
put some macros that do not differ between architectures in the
main header and remove from bits.
restructure mips header so it has the same structure as the others.

6d05d86297 add O_EXEC open mode
the linux O_PATH mode provides the necessary semantics for both the
O_SEARCH and O_EXEC modes defined and required by POSIX 2008.

b238b37a0f add O_PATH/O_SEARCH support to fcntl.h
I'm not 100% sure that Linux's O_PATH meets the POSIX requirements for
O_SEARCH, but it seems very close if not perfect. and old kernels
ignore it, so O_SEARCH will still work as desired as long as the
caller has read permissions to the directory.

4e8b0938d9 proper error handling for fcntl F_GETOWN on modern kernels
on old kernels, there's no way to detect errors; we must assume
negative syscall return values are pgrp ids. but if the F_GETOWN_EX
fcntl works, we can get a reliable answer.

67b25fe0a8 move F_DUPFD_CLOEXEC out of bits
fcntl values 1024 and up are universal, arch-independent. later I'll
add some of the other linux-specific ones for notify, leases, pipe
size, etc. here too.

a68af22926 add F_SETSIG and F_GETSIG (linux specific) to fcntl.h
F_* is in the reserved namespace so no feature test is needed

685e40bb09 syscall overhaul part two - unify public and internal syscall interface
with this patch, the syscallN() functions are no longer needed; a
variadic syscall() macro allows syscalls with anywhere from 0 to 6
arguments to be made with a single macro name. also, manually casting
each non-integer argument with (long) is no longer necessary; the
casts are hidden in the macros.

some source files which depended on being able to define the old macro
SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall()
instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL
have also been changed.

x86_64 has not been tested, and may need a follow-up commit to fix any
minor bugs/oversights.
