Mark Salyzyn cf983bcbae liblog: add android_log_logger_list management
Add list of android_log_logger_list entities as a way of
accessing the list of transport contexts from within
one of the transports.  This will enable us to iterate back
to an internal transport context which may house a last index
or signalling semaphore to propagate a wakeup on a blocking
read.

Test: gTest libcutils-tests, logd-unit-tests, liblog-unit-tests,
      logcat-unit-tests

Mark Salyzyn cfd5b080af system/core: preparation to pull back interfaces from android/log.h
Point to log/log.h where necessary, define LOG_TAG where necessary.
Accept that private/android_logger.h is suitable replacement for
log/logger.h and android/log.h.

Correct liblog/README

Effectively a cleanup and controlled select revert of
'system/core: drop or replace log/logger.h' and
'system/core: Replace log/log.h with android/log.h'.

Test: compile

Mark Salyzyn 018a96d03f liblog: split out transports into separate files
Create config_logger, logger and logger_read to house the log
interfaces. Add fake_logger, logd_logger and pmsg_logger to
house the write and read transports. Allows for an easier and
direct path to add new transports to the library.

SideEffects: None, logger benchmark performance unaffected
