Mark Salyzyn ee3b838e13 logd: statistics per-pid filter
Primarily gives access to the Chattiest TIDs and TAGs
associated with a pid.

Has a secondary effect of allowing us to pull out the
command line, comm and in some cases the associated
PACKAGE for a specific pid while the logs are still
present even if the executable is gone.

Mark Salyzyn f8e546e609 liblog: Support for ANDROID_LOG_WRAP mode flag on reader
If ANDROID_LOG_WRAP is specified, add timeout=3600 to the reader
request. logd will comply by going to sleep with the socket open.
If the start time is about to wrap or get pruned in the specified log
buffers, then wakeup and dump the logs; or wakeup on timeout,
whichever comes first.

Mark Salyzyn 43e92819fe liblog: Remove paranoia regarding logd
We are changing the log read API to allow event notification
regarding logging system data loss. We would like these out
of band events to be reported.

Mark Salyzyn 6eef417119 liblog: add pstore read
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.

Mark Salyzyn 2d3f38a6b8 liblog: introduce ANDROID_LOG_* flags
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.

- if network read/write broken up, reassemble the pieces.
- Use a 20ms poll to check if a new fragment has been
  sent by the other side.
- fixup logd-unit-tests to take a (simplified) fragment
  from the liblog changes.

Greg Hackmann 8084a53897 liblog: improve errno handling on read failure
1. socket() failures should skip close(), since sock is not an open fd
2. on other I/O related failures, preserve errno around the close() call
3. set errno to a meaningful value on check_log_success() failure
