The arm kvm.h file has been deprecated, so nobody should be including it.
Therefore, remove the hack to copy the file out of the tools directory.
Also, update to remove the arm kvm.h file.
Test: Ran generate and update script and verified only the arm kvm.h
Test: was deleted.
Test: Builds and boots on a walleye.

This means that execle() doesn't have to drag in all the path code and
shell script special case code from its relatives, for branches that
will never be taken. Specifically, it means that they disappear from the
monstrously large linker binary after this change.
A drop in the ocean of bloat, yes, but you have to start somewhere.

We are removing native bridge copy of fork.cpp, but need to
replace call to clone() when it's done for bionic's fork.
The code here will run all pre-/post-clone routines for *guest*,
while native bridge implementation will need to run the
corresponding *host* routines.

ART runs some tests on host using linux_bionic (cf.
ab/git_master-art-host). On device Bionic binaries come from its APEX,
but on host they have to be supplied separately. Since they're not part
of the SDK they are instead provided through a `module_export` module,
which is technically similar to `sdk` in the way it produces prebuilt
snapshots.

and runtime-module-host-exports

Update the generate_uapi_headers.sh where the types.h file is now in
the right place, but kvm.h is not.

.whitelisted is a list of sonames seperated by ":" just like
.shared_libs and .paths properties. It makes sense to make it appendable
using += as well ass .shared_libs and .paths.

Test: bionic-unit-tests without bionic-loader-test-libs at the expected
relative path shows the error message.

When malloc debug is enabled, using libbacktrace to unwind can
result in a deadlock. This happens when an unwind of a thread
is occuring which triggers a signal to be sent to that thread. If
that thread is interrupted while a malloc debug function is
executing and owns a lock, that thread is then stuck in the signal
handler. Then the original unwinding thread attempts to do an
allocation and gets stuck waiting for the same malloc debug lock.
This is not a complete deadlock since the unwinder has timeouts,
but it results in truncated unwinds that take at least five
seconds to complete.
Only the backtrace signals needs to be blocked because it is the only
known signal that will result in a thread being paused in a signal
handler.
Also, added a named signal in the reserved signal list for the
special bionic backtrace signal.

Since we last touched this file, the Linux kernel has added the missing
API, but time has also moved on enough to make the cost/benefit
unconvincing for Android.
