...or rather, it WILL BE code shrink when gcc become clever enough
to not emit a second, useless XORing of ebx:
31 db xor %ebx,%ebx
85 c0 test %eax,%eax
74 11 je 73 <__GI_sleep+0x73>
31 db xor %ebx,%ebx <=== ?!

__USE_EXTERN_INLINES was unused and had bit-rotted, had to fix it
when it didn't work as intended at first.

Use less stack by using same "sigset_t set" object for new and saved
signal set, remove redundant clearing of set, and do not save/restore
errno around sigprocmask(SIG_SETMASK) - it never changes it.
While at it, improve comments and make code style consistent
across sleep.c file.

According to POSIX.1-2008 standard, the following syscalls shall be
cancellation points : waitid, sleep, fdatasync, ppoll.
Further, if generic syscall is not available and stubs are
configured, provide the stub implementation for function.

*: remove checks of sigaction and sigprocmask results
in cases where they clearly can't fail:
sigaction(known_good_sig)
sigprocmask(known_good_how)

- Fixes _dl_exit()
- Implements sleep(3) for !UCLIBC_HAVE_REALTIME
- Implements usleep(3) for !UCLIBC_HAVE_REALTIME
- adds #warning about incorrect posix_fadvise{,64}()
- removes unused and unwanted uselib()
Net outcome is that an allnoconfig with HAVE_SHARED is now about 88k instead
of formerly 130k.

calls the libc.so version, never the wrapped version in libpthread.so that's a
cancellation point.

* nanosleep returns the remaining time, not the time slept
* nanosleep only fills out the remaining time if it returns -1 (ie., the
sleep was interrupted)
