The AsyncInvoker destructor waits for all invoked tasks to be complete
(in other words, all AsyncClosures to be destructed). They were using an
event to wake up the destructor, but a race made it possible for this
event to be dereferenced after it's destroyed.
This CL makes the event reference counted, such that if the destructor
runs right after AsyncClosure decrements "pending_invocations_",
setting the event will be a no-op, and the event will be destructed
in the AsyncClosure destructor.
This CL also fixes a deadlock that may occur for "re-entrant"
invocations. The deadlock occurs if the AsyncInvoker is destroyed on
thread A while a task on thread B is running, which AsyncInvokes a task
back on thread A.
This was causing pending_invocations_ to end up negative, because
an AsyncClosure that's never added to a thread's message queue (due to
the "destroying_" flag) caused the count to be decremented but not
incremented.

I used a command like this to update the paths:
perl -pi -e "s/webrtc\/base/webrtc\/rtc_base/g" `find webrtc/rtc_base -name "*.cc" -o -name "*.h"`
Changes since last attempt: Some system headers were moved back to their original location since on Windows compilation breaks otherwise.

Reland the base->rtc_base without adding stub headers (will be
done in follow-up CL). This preserves git blame history of all files.

This refactoring takes a careful approach to avoid rushing the change:
* stub headers are left in all the old locations of webrtc/base
* existing GN targets are kept and now just forward to the moved ones
using public_deps.
The only exception to the above is the base_java target and its .java files,
which were moved to webrtc/rtc_base right away since it's not possible
to use public_deps for android_library.
To avoid breaking builds, a temporary Dummy.java file was added to
the new intermediate target in webrtc/rtc_base:base_java as well to avoid
hitting a GN assert in the android_library template.
The above approach should make the transition smooth without breaking
downstream.
A helper script was created (https://codereview.webrtc.org/2879203002/)
and was run like this:
stub-headers.py -s webrtc/base -d webrtc/rtc_base -i 7634
stub-headers.py -s webrtc/base/numerics -d webrtc/rtc_base/numerics -i 7634
