FORTIFY_SOURCE: remove memcpy overlap checks

These checks haven't been as useful as I hoped, and it's
causing a false positive finding.  Remove the overlap
compile time checks.

glibc 2.15 treats errno as signed in strerror(3).

And the only reason I hadn't done that in bionic is because I wanted to behave
the same as glibc.

Add stack canaries / strcpy tests.

Add a test to ensure that stack canaries are working
correctly. Since stack canaries aren't normally generated
on non-string functions, we have to enable stack-protector-all.

Add a test to ensure that an out of bounds strcpy generates
a runtime failure.

fix strerror_r test

e6e60065ff093ff8c859ab146cf543531cb1967c modified strerror_r to
treat errno as signed. However, the change to the test code
modified the "strerror" test, not the "strerror_r" test.

Make the same change for the strerror_r code.

FORTIFY_SOURCE: optimize

Don't do the fortify_source checks if we can determine, at
compile time, that the provided operation is safe.

This avoids silliness like calling fortify source on things like:

  size_t len = strlen("asdf");
  printf("%d\n", len);

and allows the compiler to optimize this code to:

  printf("%d\n", 4);

Defer to gcc's builtin functions instead of pointing our code
to the libc implementation.

Add optimized version of memcpy for Cortex A9

Adds new code to memcpy function, optimized for Cortex A9.
Adds new ARM-only loop, for operations where source and
destination are aligned.

Copyright (C) ST-Ericsson SA 2010

Modified neon implementation to fit Cortex A9 cache line size,
for those running 32 bytes L2 cache line size.
Also split the implementation in aligned and unaligned access,
for those that allows unaligned memory access with Neon.
For totally aligned operations, arm-only code is used.
