Tom Cherry 2a6811b4d1 liblog: use a rwlock for writer initialization 
The current system of using atomics isn't thread safe and may result
in doubly closing FDs or closing actively used FDs.  The safest way to
do this is to use a rwlock, which should not have a much higher
overhead than the atomics do, as a vast majority of the time, there
will not be writers.

This moves us further away from using the transport interface, which
will be removed.  Each writer should be self contained, without a
separate open or available function.

Also, keep the pmsg fd open if it is opened by
__android_log_pmsg_file_write().  This fd was closed due to issues
with zygote, but it looks like it is only called by recovery now, so
there is no reason to close this fd at the end of that function.

Test: logging works, liblog-unit-tests
