We still do not have any users of the 'frontend' interface, let's
right a wrong and rename it to 'transport' as it makes more sense.
Renames android_log_set_frontend, android_log_get_frontend and
include/log/log_frontend.h.

- Create the local-only logger module
- Add LOGGER_LOCAL flag to android_set_log_frontend to enable
- Permit log reader for host compilation
android_set_log_frontend(LOGGER_LOCAL) will result in logs going
into application local memory. logcat can not retrieve the data,
the user must utilize the log reading interface directly to
acquire their own logs. Some local logger tests dropped as they
represent testing other liblog facilities. Other local logger
tests dropped because we make the conscious decision to not
support LOG_ID_SECURITY logging.
ToDo: Some local logger tests dropped because of missing
functionality associated with blocking reader.

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.

log/logger.h pieces moved into log/log.h. Correct for some
minor Android Coding standards.

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'.

Allow our own libraries to use this privately instead of
running the less efficient get_properties and doing the math.

__android_log_pmsg_file_write() will open /dev/pmsg0 if not
already, and will close it if we opened it.
Added atomic access to the android_log_context as insurance.
Fortify and correct pmsg tests.

Always used in combination with log/logger.h except in log_time.cpp,
and not used externally. As a result liblog has to support stl, a
small price to pay since goal is to convert liblog to C++ internally.

Bionic getuid() and getpid() calls cache to reduce the need to
perform a syscall, and also reset their own cache after a vfork().
No more need for liblog to be performing this flawed cache operation.

- add optimized & cached LIBLOG_HIDDEN __android_log_is_debuggable()
- check when writing, either LOG_ID_SECURITY, SafetyNet or
debuggable when pushing content to the pmsg buffer.

- Secure LOG_ID_SECURITY in reader and writer
- if writer transport says not available, do not write to that log id

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
