f4c948a9e9 Move the meat of <features.h> into <sys/cdefs.h>.
This way it's a lot harder for us to screw up (since we should always
be including <sys/cdefs.h> anyway).

5f5cc45cf0 Fix <features.h> (_BSD_SOURCE and _GNU_SOURCE).
<features.h> is supposed to take user-settable stuff like _GNU_SOURCE
and _BSD_SOURCE and turn them into __USE_GNU and __USE_BSD for use in
the C library headers. Instead, bionic used to unconditionally define
_BSD_SOURCE and _GNU_SOURCE, and then test _GNU_SOURCE in the header
files (which makes no sense whatsoever).

dd09699fae Use __LP64__ instead of __LP32__ in sched.h
Gcc defines only __LP64__ so testing __LP32__ will always be false.

bbb34f9536 <sched.h> should offer both __sched_priority and sched_priority.
If glibc hadn't already done things this way round, I'd have
called the field sched_priority and the macro __sched_priority
since that would seem less likely to cause trouble, but glibc
source compatibility is probably more important.

887e1140fe Clean up <sched.h>.
This patch switches to using the uapi constants. It also adds the missing
setns system call, fixes sched_getcpu's error behavior, and fixes the
gensyscalls script now ARM is uapi-only too.

72e6fd4242 <sched.h>: Add sched_getcpu() and cpu_set_t
This adds the cpu_set_t type definition and related functions
and macros used to handle CPU thread affinity.

  sched_getcpu()
  sched_setaffinity()
  sched_getaffinity()

bb5581ad6e libc: tag missing functions in system headers.
This matches recent changes in the NDK header.
We enclose missing functions in #if 0 .. #endif blocks
with a clear "MISSING" in comments in order to locate
them later.

97cf7f3394 Implement clone() C library function properly.
Only provide an implementation for ARM at the moment, since
it requires specific assembly fragments (the standard syscall
stubs cannot be used because the child returns in a different
stack).
