Although ever present, an increased regression introduced with
commit b6bee33182 (liblog: logd:
support logd.timestamp = monotonic).
A signal handler can interrupt in locked context, if log is written
in the signal handler, we are in deadlock. Block signals while we
are locked. Separate out timestamp lock from is loggable lock to
reduce contention situations. Provide a best-guess response if
lock would fail in timestamp path.

- '-v epoch' prints seconds since Jan 1 1970
- '-v monotonic' print cpu seconds since start of device
- '-T sssss.mmm...' as alternate tail time format
NB: monotonic is a best estimate and may be out by a few ms
given the synchronization source clue accuracy.

- '-v year' modifier adds the four digit year prefix
- '-v <timezone>' modifier sets and prints the timezone suffix
- Only promise in logcat to support UTC as a timezone since
all others are based on the configured environment
- '-v zone' modifier toggles the timezone suffix on or off
- '-T YYYY-MM-DD HH:MM:SS.mmm...' format is added

- added printable format modifier:
logcat -v printable
- opencoded borrowed individual utf8 validity checking algorithm
from utf8_length() in libutils/Unicode.cpp
- if considered basic one-character ASCII, use popular \x escape
sequences for non-printable
- logprint convert to C comments to drop mixed-mode

In order to make it easier to find radio system logging
mistakes, if LINT_RLOG is defined we will remove all the
definitions for ALOG* and SLOG*, as well as the log ids
to introduce compile and link errors.

Used to pull the Android log messages after a reboot. Adding
an ANDROID_LOG_PSTORE flag to the mode parameter in calls to
android_logger_list_alloc() and android_logger_list_alloc_time().
The side effects are that android_logger_clear() and
android_logger_list_read() will react with the user space
pstore driver. Forms a companion to the pstore console logs.

Move away from using POSIX open(2) flags and introduce ANDROID_LOG_* flags to
replace them. Add security by preventing random mode flags from getting into
underlying POSIX calls. ANDROID_LOG_* flags overlap POSIX O_* flag definitions.

- take android_testLog from the bonepile and resurrect
- android_testLog is used, and makes sense in its current context
as a holder for Android Logging policy.
- Default level when not specified is ANDROID_LOG_VERBOSE for
eng and userdebug, and ANDROID_LOG_DEBUG for user.
NB: Properties, which are associated with __android_log_is_loggable are
not to be adjusted in user release; it would be useful at that juncture to
return a constant of (0) for VERBOSE, and a (1) for others on user builds.
Or default level to drop to ANDROID_LOG_DEBUG for all in future.

This should probably be in libcutils instead, so code that needs to
care about Windows can use readv/writev.

This patch adds a new '-v color' option to logcat so that the output is
colored similar to the ones in DDMS. Simply type "adb logcat -v color"
to use it. Works well with bash in gnome-terminal. NO GUARANTEE IT WILL
WORK ON A NON xterm STYLE TERMINAL.

Implement LOG_EVENT_STRING, so that native code can create new

to the event log.

- liblog android_logger_get_log_size and android_logger_get_readable_size
adjusted to return long instead of int because of -G flag extending range
NB: ifdef'd only for userdebug and eng builds
- liblog Add android_logger_[sg]et_prune_list and android_logger_set_log_size
- logcat Add -P, -p and -G flags
- logd Add LogWhiteBlackList and configurable log size

exists and includes log/log.h in order to support the many existing
