Mark Salyzyn 10bdf61e5f liblog: add __android_log_pmsg_file_write
(cherry pick from commit d4b061bde2)

- This is considered an Android Private function, not exported
  for general use.
- goal is to record a file's content into a series of log
  messages into pmsg, to be retrieved after a reboot for
  transfer to a persistent location.
- filename reference is converted to a tag-unique
  "<dirbase>:<filebase>".
- buffer and length representing the filename contents are
  recorded, along with a sequence number placed into the nsec
  time field to ANDROID_LOG_PMSG_FILE_MAX_SEQUENCE.
- Add a gTest for this function.

Mark Salyzyn facf94c74a liblog: split out transports into separate files
(cherry pick from commit 018a96d03f)

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
