Following up on comments from I40c66ff9e638b306878ada006bc2c98f2346e77a.
My best attempt at a name that conveys "a test that fails to compile in
N different ways with FORTIFY enabled, and is intended to be used with
either FileCheck, or as a cheap way to check that FORTIFY is getting
properly disabled given some set of flags."
Bug: None
Test: mma.

Having FORTIFY enabled for clang-tidy adds no value, and breaks some
heuristics for recognizing standard library functions (see the bug).
This also disables FORTIFY for the static analyzer (which we use
through clang-tidy), because it presumably tries to recognize standard
library functions through similar heuristics.
Bug: 36664104
Test: mma with and without the patch to cdefs. New test breaks without.

The tests that use LD_CONFIG_FILE environment variable shouldn't be run
on non-production devices because LD_CONFIG_FILE is only for debuggable
builds. We have used the build-time flag USE_LD_CONFIG_FILE, which is
set for the debuggable builds, to conditionally include or exclude the
tests. However, this can be a problem when 1) the device is not
debuggable but 2) the CTS itself is built with debuggable target. So,
instead of relying on the build-time flag USE_LD_CONFIG_FILE, the tests
now check the debuggability of the device and skip the tests when it
isn't debuggable.

Test: 1) flash user build image to a 2017 pixel device.
2) build cts with 'userdebug' build target
3) CtsBionicTestCases pass on the device

iOS 10 has <sys/random.h> with getentropy, glibc >= 2.25 has
<sys/random.h> with getentropy and getrandom. (glibc also pollutes
<unistd.h>, but that seems like a bad idea.)
Also, all supported devices now have kernels with the getrandom system
call.
We've had these available internally for a while, but it seems like the
time is ripe to expose them.

This is the FreeBSD implementation, plus some tests. The FreeBSD
implementation includes the GNU extensions and seems to be what
iOS is using too, which should provide bug compatibility for app
developers.
The code unfortunately uses a lot of stack, and uses FreeBSD locale
implementation that we don't have, but it does seem better maintained
than the other BSDs.

Well, all except <threads.h> which we have no current plans to implement.
The only thing this turned up is that clang's <float.h> doesn't define
FLT_HAS_SUBNORM/DBL_HAS_SUBNORM/LDBL_HAS_SUBNORM, so for now we assert
that those are missing so that when we get a fixed clang, we notice.
Also the <tgmath.h> is utterly perfunctory, but seems like an appropriate
amount of effort to put in.

FORTIFY's *_chk functions mess with ASAN's library function
interceptors, which can apparently result in false-positives.
Since adding even more complexity to every run-time check condition in
FORTIFY doesn't seem like a great idea, and the majority of our builds
will still use FORTIFY anyway, turning FORTIFY off here seems
reasonable.

With ld.config.txt, we now have multiple built-in namespaces other than
the default namespace. Libs (and their dependents) listed in LD_PRELOAD
must be visible to those additional namespaces as well.
This also adds a debugging only feature: path to the linker config file
can be customized via LD_CONFIG_FILE environment variable. This works
only for debuggable builds.

* TTYDEF_OFLAG referred to the BSD OXTABS constant instead of the Linux XTABS,
so references to it wouldn't compile.
* CEOL was incorrect (compared to `stty -a`).
* ttydefchars wouldn't compile (removed rather than attempt to fix something
of unclear utility).
