<machine/asm.h> was internal use only.
<machine/fenv.h> is quite large, but can live in <bits/...>.
<machine/regdef.h> is trivially replaced by saying $x instead of x in
our assembler.
<machine/setjmp.h> is trivially inlined into <setjmp.h>.
<sgidefs.h> is unused.

arm32 is still missing vdso (at least on some kernels).
This commit adds explicit check for it and skip the test
if AT_SYSINFO_EHDR is not set.

While this was never an inline, this function alone has caused most of
the bug reports related to _FILE_OFFSET_BITS=64. Providing an inline
for it should allow a lot more code to build with _FILE_OFFSET_BITS=64
when targeting pre-L.
Test: make checkbuild
Test: built trivial cc_binary for LP32 against API 14 with
_FILE_OFFSET_BITS=64 set

On aarch64/x86/x86_64 add a macro that inserts a cfi directive that will
stop unwinding.
For arm, clang doesn't allow emitting .cantunwind, so add a comment and
leave it the same as it current is.
Add this macro to __libc_init and __start_thread.
Also, remove duplicate compilation of libc_init_static.cpp that already
includes the static library that includes that file.
Bug: 15469122
Test: Did unwinds using new unwinder tool (unwind) and debuggerd -b
Test: and verified new unwinder works on aarch64/x86/x86_64.
Test: Verified that it works on old unwinder for aarch64/x86, but
Test: x86_64 doesn't work properly, but as well as before.

The newest of these clocks was added in Linux 2.6.12, so no need for runtime
checks.
Add CTS tests that we can actually use the various clocks.

This reverts commit 81b175747d.
Reason: 02586a2a34 fixed the bug that
prevented us from using LD_PRELOAD with multiple namespaces.

3. in the home screen, hold vol-up/down together
4. device does not reboots and talkback shortcut is toggled

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.

Stop allocating and deallocating memory as part of the test itself.
There's still the fopen, but since our stdio reuses existing structs,
that doesn't seem to be a problem in practice.

In the future, target.linux will apply to all targets running a linux kernel
(android, linux_glibc, linux_bionic). So move all current users to the specific
linux_glibc.
There will be another cleanup pass later that will move some instances back to
target.linux if the properties should be shared with target.android and
target.linux_bionic, but target.linux needs to be removed first.

It's almost 2018, Linux 3.17 -- the first kernel with getrandom(2) --
was released in October 2014, and being able to assume getrandom lets
us simplify and improve some security-related code in libc, and revert a
hack to getentropy that's been necessary in the meantime. Only the fugu
kernel doesn't have getrandom(2) at this point, and that's EOL.

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.

Linux.
