Eric Blake a4961ccd3f Revert "headers: avoid bareword attributes" for clang
This reverts most of commit 979d467ff6.

We cannot avoid some bareword attributes until clang is fixed to
properly support __-decorated attributes; see this bug:
https://bugs.llvm.org/show_bug.cgi?id=34319

The macros in question expand to the empty string under gcc, so
only compilation under clang is affected, and since clang has the
bug, the obvious solution is to roll back the changes, and document
the issue.

Eric Blake 979d467ff6 headers: avoid bareword attributes
Always use the __-decorated form of an attribute name in public
headers, as the bareword form is in the user's namespace, and we
don't want compilation to break just because the user defines the
bareword to mean something else.

Yao Qi 32ca315312 Don't fetch command line options without semi-hosting
Nowadays, the code fetching command line options via semi-hosting are
unconditionally pulled in, so that the semi-hosting code is still
there even I compile with option --specs=nosys.specs.

gdb ./aarch64-none-elf/libgloss/aarch64/crt0.o

(gdb) disassemble _start

   0x0000000000000050 <+80>:	ldr	x1, 0x128 <_cpu_init_hook+48>
   0x0000000000000054 <+84>:	mov	w0, #0x15
   0x0000000000000058 <+88>:	hlt	#0xf000

This patch fixes this problem by wrapping the code by ARM_RDI_MONITOR.
When semi-hosting is not used, set command line options to NULL.

Tamar Christina 61ddc7a436 Fix crt0 overwriting.
On AArch64 we currently always link in crt0 regardless of if another
one is being provided by something else, like rdimon.a. This was never
an issue before as nosys was not supported on AArch64.

This updates the specs to supply a different crt0 when a semihosting
call is required.

Sebastian Huber b0f271d1db Proper locking for getchar() and putchar()
Add internal inline functions _getchar_unlocked() and
_putchar_unlocked() if __CUSTOM_FILE_IO__ is not defined.  These
functions get _REENT only once.  Use them for getchar_unlocked() and
putchar_unlocked().  Define getchar() and putchar() to these unlocked
internal functions if __SINGLE_THREAD__ is defined, otherwise use the
external functions to use proper locking of the FILE object.

Assumes that __SINGLE_THREAD__ is not defined if __CYGWIN__ is defined.

- Introduce inline helper pthread_convert_abstime.  It converts

- Use this function from pthread_cond_timedwait and semaphore::timedwait

- Merge semaphore::_wait and semaphore::_timedwait into single _wait
  method, taking a LARGER_INTEGER timestamp.

Corinna Vinschen e6c75c1de1 cygwin: select: use UNICODE console functions
For historical reasons peek_console was calling the functions
PeekConsoleInputA and ReadConsoleInputA.  However, these functions are
not working correctly under at least codepage 65001 (UTF-8) on systems
prior to Windows 10.

Use PeekConsoleInputW and ReadConsoleInputW instead, which work
correctly under all systems and all codepages.
