* commit '9aac38249b579282ae8eaa630de3deaf97c4edff':
libc: remove C++ comments from public headers.
This reverts commit 80fba9a2fe,
which caused the system to not boot anymore, aborting with:
"java.lang.RuntimeException: Missing static main on com.android.server.SystemServer".

In order not to conflict with the symbols defined in file
libc/netbsd/getaddrinfo.c, this patch makes the internal/helper
functions static.

Ideally __libc_android_abort would be static, but it could not be
because gcc would not allow calling a static function from an asm
statement. Instead, using GCC visibility is work around.

1. Make the feature test work by excluding known-deficient processors, so
we don't have to maintain a complete list of all the processors that support
REV and REV16.
2. Don't abuse 'register' to get an effect similar to GCC's +l constraint,
but which was unnecessarily restrictive.
3. Fix __swap64md so _x isn't clobbered, breaking 64-bit swaps.
4. Make <byteswap.h> (which declars bswap_16 and friends) use <endian.h>
rather than <sys/endian.h>, so we get the machine-dependent implementations.

The __ARM_HAVE_LDREX_STREX define is used to replace
the swp instruction with ldrex/strex for ARM architecture
greater than 6 (armv6, armv7 etc.). However the include
file, cpu-features.h, which defines this flag was never
included.

ARMv6 ISA has several instructions to handle data in different byte order.
For endian conversion (byte swapping) of single data words, it might be a
good idea to use the REV/REV16 instruction simply.

The implementation was using a double-checked locking approach that
could break on SMP.
In addition to the barriers I also switched to a volatile pointer. I
don't think this will matter unless gcc can conclude that _normal_lock
can't affect *once_control, but I figured it was better to be safe.
(It seems to have no impact whatsoever on the generated code.)
Bug 3022795.
