083b037c07 logd: liblog: logcat: Add LOG_ID_SECURITY
- Largish commit, buffer and access controls done together
- Add LOG_ID_SECURITY binary content log
- Add "default" meta buffer
- allow LOG_ID_SECURITY only from AID_SYSTEM and AID_ROOT UID & GID
- Use __android_log_security() to gate logging
- Add __android_log_security_bwrite() native access to security
  logging.
- Add liblog.__security_buffer end-to-end gTest

c158456f50 liblog: __android_log_is_loggable support global properties
- Add support for "log.tag" and "persist.log.tag" global
  logging properties, effectively a runtime default minimum
  logging level.
- Add a thread-safe single level cache plus selective logic for the
  four properties being checked to help speed up logging decision
  on subsequent identical calls.
- Using new __system_property_area_serial() to make for
  efficient (<100ns) handling of cache misses. Despite adding
  two new properties, we are 8 times faster on subsequent calls
  even if the properties do not exist.
- A NULL or blank tag is no longer directed to return default,
  it will check the pair of global logging properties first.
- Add liblog.is_loggable gTest
- Fixup liblog.android_logger_get_, allow no content in crash buffer
- Fixup liblog.max_payload, lowered logd priority increases latency

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.
