119cb55d43 gtest_repeat should allow negative values. 
If you pass in a negative value to gtest_repeat, it should run forever.
The new runner didn't allow this, now it does.

8fdb3419a5 linker: never mark pages simultaneously writable / executable 
When the Android dynamic linker handles a text relocation,
it first relaxes the permissions on the segment being modified,
performs the modifications, and then restores the page permissions.
The relaxation worked by adding PROT_WRITE to whatever protection
bits were set in the section. In effect, the pages were getting set
to PROT_READ|PROT_WRITE|PROT_EXEC, modified, then restored to
PROT_READ|PROT_EXEC

The SELinux kernel code differentiates between 4 different kinds
of executable memory:
* Executable stack (execstack)
* Executable heap (execheap)
* File-based executable code which has been modified (execmod)
* All other executable memory (execmem)

The execmod capability is only triggered by the kernel when a
dirty but non-executable mmap()ed page becomes executable. When that
occurs, an SELinux policy check is done to see if the execmod capability
is provided by policy.

However, if the page is already executable, and PROT_WRITE is added
to the page, it's considered an execmem permission check, not an execmod
permission check.

There are certain circumstances where we may want to distinguish between
execmod and execmem. This change adjusts the dynamic linker to avoid
using RWX pages, so that an RX -> RW -> RX transition will properly
be detected as an execmod permission check instead of an execmem permission
check.

d6bf3d5e19 Don't export new/delete from libc shared libraries. 
This used to be handled by -fvisibility=hidden on libc_cxa, but that
was broken by the resolution of https://llvm.org/PR22419 (introduced
to Android in today's clang update).

Now we just use a version script that prevents these from being
re-exported from our shared libraries.

56b2768176 stubs missing include for string.h 
stubs.cpp gets string.h inherited from private/android_filesystem_config.h
it should not rely on this in the future. The intent is to move fs_config
function into libcutils and thus deprecate any need for string.h in this
include file.
