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.

- For prevent confuse about what BSD license variant we used, 2- or
3-clause license, we change the license to FreeBSD license to make
it unambiguously refers to the 2-clause license.
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.

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.
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.

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.

- pthread_mutex::lock now takes a PLARGE_INTEGER timeout pointer
and uses that in the call to cygwait.

- Introduce inline helper pthread_convert_abstime. It converts
an absolute timespec to a Windows LARGE_INTEGER timestamp,
depending on the used clock.
- 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.

This is copied from musl (MIT license). This is newer and more thorough
than that of FreeBSD currently shipped only on Cygwin.
