The implementation of the POSIX access() function is nothing machine
specific like memcpy(), etc. Move it back to the system domain. This
avoids problems due to the include search order of the Newlib/GCC build
which picks up machine includes before system includes.

When simulating arm code, the target program startup code (crt0) uses
semihosting invocations to get the command line from the simulator. The
simulator returns the command line and its size into the area passed in
parameter. (ARM 32-bit specifications :
http://infocenter.arm.com/help/topic/com.arm.doc.dui0058d/DUI0058.pdf
chapter "5.4.19 SYS_GET_CMDLINE").
The memory area pointed by the semihosting register argument is located
in .text section (usually not writtable (RX)).
If we run this code on a simulator that respects this rights properties
(qemu user-mode for instance), the command line will not be written to
the .text program memory, in particular the length of the string. The
program runs with an empty command line. This problem hasn't been seen
earlier probably because qemu user-mode is not so much used, but this can
happen with another simulator that refuse to write in a read-only segment.
With this modification, the command line can be correctly passed to the
target program.
Changes:
- libgloss/arm/crt0.S : Arguments passed to the AngelSWI_Reason_GetCmdLine
semihosting invocation are placed into .data section instead of .text
- libgloss/aarch64/crt0.S : Idem for aarch64 AngelSVC_Reason_GetCmdLine
semihosting.
This leads to excessive lag when stracing processes if the inferior
process checks the process table. The reason is that ppid isn't set
in the procinfo memory of the dynamically loading strace itself.

Add new SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE flag to
CreateSymbolicLinkW call when running on W10 1703 or later.
Don't do that on older versions to avoid ERROR_INVALID_PARAMETER.
Preliminary, needs testing. There's an off-chance that the
flag results in the same ERROR_INVALID_PARAMETER on 1703 if the
developer settings are not enabled.

RtlGetNtVersionNumbers returns the build number with some upper bits
set for no apparent reason. The fact that RtlGetNtVersionNumbers is
undocumented doesn't exactly help.
Just filter out the upper WORD for now. If build numbers are in
danger to become 6 digit numbers, re-evaluate.
Always retrieve FileCompressionInformation for non-empty

This fixes stat.st_blocks for files compressed with CompactOS method.

Recent versions of gcc are optimizing away the TLS buffer allocated in
main, so we need to tell gcc that it's really used. RtlSecureZeroMemory
accomplishes this while also inlining the memset.

ARM EABI toolchains can optionally use the "hf" suffix to identify

previous commit 4c90db7bc8 introduced
a compile time error because libm/common/s_infconst.c used the remove
__fmath, __dmath, and __ldmath union types.
Since this is very old, and unused for a very long time, just drop the
file and thus the __infinity constants entirely.
Exception: Cygwin exports __infinity from the beginning. There's a very,
VERY low probability that any existing executable or lib still uses this
constant, but we just keep it in for backward compat, nevertheless.

Make the system queue header file fully usable within C++ programs by
adding macros to define class lists.
This change is backwards compatible for all use within C and C++
programs. Only C++ programs will have added support to use the queue
macros within classes. Previously the queue macros could only be used
within structures.
The queue.3 manual page has been updated to describe the new
functionality and some alphabetic sorting has been done while
at it.

For example, the FreeBSD GCC (4.2.1) has a spotty support for that
feature. If the static keyword is used with an unnamed array parameter
in a function declaration, then the compilation fails with:
error: static or type qualifiers in abstract declarator
The feature does work if the parameter is named.
So, the restriction introduced in this commit can be removed when all
affected function prototypes have the workaround.

For consistency with the qualifiers added in r310977, define a new
qualifier _Null_unspecified which is also defined in clang 3.7+.
Add two new macros:
__NULLABILITY_PRAGMA_PUSH
__NULLABILITY_PRAGMA_POP
These are for use in headers when we want avoid noisy warnings if
some pointers are left without nullability annotations.
These are added with way ahead of their first use to teach the GCC
ports headers of their existance before their first use.
This was meant to be used by a future FORTIFY_SOURCE implementation.
Probably for good, FORTIFY_SOURCE and this particular GCCism were never
well supported by clang or other compilers. Furthermore, the technology
has long since been replaced by either static checkers, sanitizers, or
even just the strong stack protector that was enabled by default.
Drop __gnu_inline to avoid cluttering the headers.
