set errno to ENOENT in getauxval per glibc 2.19
Bionic's getauxval(...) implementation returns zero when entries are
missing. Zero can be a valid value, so there is no unambiguous way of
detecting an error. Since glibc 2.19, errno is set to ENOENT when an
entry is missing to make it possible to detect this. Bionic should match
this behavior as code in the Linux ecosystem will start relying on it to
check for the presence of newly added entries.

Move the meat of <features.h> into <sys/cdefs.h>.
This way it's a lot harder for us to screw up (since we should always
be including <sys/cdefs.h> anyway).

Make sure that the same tests are on all platforms.
In order to be able to generate a list of tests for cts, the same set of
tests must exist across all platforms. This CL adds empty tests where a
test was conditionally compiled out.
This CL creates a single library libBionicTests that includes all of
the tests found in bionic-unit-tests-static.
Also fix a few missing include files in some test files.
Tested by running and compiling the tests for every platform and
verifying the same number of tests are on each platform.

libc: add getauxval()
Add support for getauxval(). This method allows a program an easy way
to retrieve information from the kernel auxiliary vector, and will
hopefully replace other clumsy ways of accessing this same information.
This particular function was also added to glibc in glibc 2.16.
See the following URLs for more details.

This change is a prerequisite for bug 7959813.
