No longer as necessary once we add
liblog: Instrument logging of logd write drops
Although this provided an indication of how close statistically we
were to overloading logd it is simpler to understand fails thus to
hunt and peck a corrected value for /proc/sys/net/unix/max_dgram_qlen

- merge common fragments
- Side Effects: none

* Only enabled for dev builds because halves performance.
- Used to establish if /proc/sys/net/unix/max_dgram_qlen
is appropriate for the platform
(see logd/LogStatistics.cpp comments)
- enabled if logd.dgram_qlen.statistics is not zero/empty
Change-Id: Ib8ecfeb75b6f0f954c099a6b1032b8afb5efcbd4
- 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
