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.

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.

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
value.

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.

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.

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.
