The test was failing due to a kernel vDSO that was linked without
--eh-frame-hdr. The kernel bug is fixed for at least the goldfish and
cuttlefish devices.

Test: bionic unit tests, on goldfish and cuttlefish

On cf_x86_phone-userdebug, both of the unwind through signal
tests fail. This has been failing forever, but seems to have suddenly
become an issue, so disable while I try to figure out why this is happening.

Test: Ran on emulator and verified tests are skipped.

We saw crashes from pthread_exit+debuggerd on LP32
(https://issuetracker.google.com/72291624), and it seems like the
equivalent problem should exist with system(3). I fixed posix_spawn(3)
as part of that bug, so the easiest fix is probably to reuse that.

Modify the test slightly to make sure that the unwinder properly unwinds
through at least 2 frames outside of the signal handler. This guarantees
that if the first frame outside of the handler happens to be garbage,
this test will fail.

Test: Ran the unit tests on fugu, angler (both 32 bit and 64 bit).

When there is an error detected, the code runs forever and then times
out without any indication of what happened. Change it so that error
messages are printed and the test fails.

This change provides __restore/__restore_rt on x86 and __restore_rt on
x86_64 with unwinding information to be able to unwind through signal
frame via libgcc provided unwinding interface. See comments inlined for
more details.
Also remove the test that had a dependency on
__attribute__((cleanup(foo_cleanup))). It doesn't provide us with any
better test coverage than we have from the newer tests, and it doesn't
work well across a variety architectures (presumably because no one uses
this attribute in the real world).
Tested this on host via bionic-unit-tests-run-on-host on both x86 and
x86-64.

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.

Kernel provides virtual DSO for stack unwinding/exception handlind info for
signal usage case. Stack unwinding routines use 'dl_iterate_phdr' function
for additional DWARF info gathering from DSOs. Patch enables virtual DSO
enumeration via dl_iterate_phdr function.
