Sebastian Pop 9938a64ca9 aarch64: optimize the unaligned case of memcmp 
This brings to newlib a performance improvement that we developed in Bionic
libc.  That change has been submitted for review to Bionic libc:
https://android-review.googlesource.com/418279

A similar patch has been submitted for review in glibc:
https://sourceware.org/ml/libc-alpha/2017-06/msg01143.html

Patch written by Vikas Sinha and Sebastian Pop.

The performance was measured on the bionic-benchmarks on a hikey (aarch64 8xA53)
board. There was no performance change to the existing benchmark
and a performance improvement on the new benchmark for memcmp
on the unaligned side. The new benchmark has been submitted for
review at https://android-review.googlesource.com/414860

The overall performance improves by 18% for the small data set 8
and the performance improves by 450% for the large data set 64k.

The base is with the libc from /system/lib64. The bionic libc
with this patch is in /data.

Thomas Preud'homme 0c081aa62c Fix guard for siginfo_t and pthread_t definition 
Commit 8a3b3bb4d7 changed the guard on
some functions from _POSIX_THREADS to __POSIX_VISIBLE. As a consequence,
some use of siginfo_t and pthread_t became visible under configurations
where _POSIX_THREADS is unset but __POSIX_VISIBLE is. Build then fails
because the definition of those types are still unavailable.

This commit make those type definition visible for __POSIX_VISIBLE
configurations. This requires moving the siginfo_t definition out of the
RTEMS specific definitions in sys/signal.h while still guarding it
against cygwin case.

Erik M. Bray 5ca286666a Ensure that send() interrupted by a signal returns sucessfully 
When SA_RESTART is not set on a socket, a blocking send() that is
interrupted mid-transition by a signal should return success (and
report just how many bytes were actually transmitted).

The err variable used here was not always guaranteed to be set
correctly in the loop, so better to just remove it and call
WSAGetLastError() explicitly.

Yaakov Selkowitz dde6af6f82 Export XSI sigpause 
There are two common sigpause variants, both of which take an int argument.
If you request _XOPEN_SOURCE or _GNU_SOURCE, you get the System V version,
which removes the given signal from the process's signal mask; otherwise
you get the BSD version, which sets the process's signal mask to the given

Corinna Vinschen 8eada33223 cygwin: readdir: don't lookup mount target inodes 
So far Cygwin's readdir returned the inode number of a mount target
in d_ino, rather than the actual inode number of the mount point in
the underlying filesystem.  This not only results in a performance
hit if the mount target is a remote FS, it is also not done on other
POSIX systems.

Remove the code evaluating the mount target inode number.

Joe Lowe 0a9edd73e3 readdir() with mount point dentry, return mount point INO 
This patch fixes a minor compatibility issue w/ cygwin mount point handling in
readdir(), compared to equivalent behavior of Linux and MacOS. dentry.d_ino
should indicate the INO of the mount point itself, not the target volume root
folder.

Changed return type from readdir_check_reparse_point to uint8_t, to avoid
unnecessarily being implicitly cast to and from a signed int.

Renamed a related local variable "attr" to "oattr" that was eclipsing a member
variable with the same name.

Silviu Baranga efaef1bba2 Don't overread or write memory returned by _DTOA_R 
Don't over-read memory returned by _DTOA_R, and never write to it
since the result might be a string literal.

For example, when doing:
  swprintf(tt, 20, L"%.*f", 6, 0.0);

we will get back "0".

Instead, write the result returned by _DTOA_R to the output buffer.
After this, write the 0 chars directly to the the output buffer
(if there are any). This also has the (marginal) advantage that
we read/write less memory overall.
