Tom Cherry 2238ce2d7f liblog: remove stderr logger
There are no users of the liblog stderr logger, but 66 users of
android::base::StderrLogger.  We'll prefer that format and work to
merge it into liblog.

Bernie Innocenti 804e7d8c4f Fix clang-tidy warnings in log_time.h
- Zero initialize log_time instances by default
 - Disable implicit conversions by making constructors explicit
 - Explicitly initialize to EPOCH in most places
 - Change sniffTime() to avoid in-place modification of a log_time

I stopped here, but we could consider following up with a more invasive
change to make log_time instances immutable and perhaps also remove the
default constructor to force explicit initialization to EPOCH.

Tom Cherry 3b4bddc638 Remove liblog's rate limiting
After a few years of being available, there only ended up being one
user of this, so it is clear that logd's duplicate message mechanism
is the favored solution.

The one user of this rate limiting is questionable as is, since due to
the nature of storaged, the mainloop only runs once per minute by
default as is, so there is essentially nothing to be gained by rate
limiting any further.

Bug: http://b/69933090
Bug: http://b/69933068

MinGW uses gnu_printf to force C99 printf analysis with GCC, but clang
does not support gnu_printf.  So just use the default that's used for
other platforms.  This also mirrors upstream commit
015e637b4b/.

Jiyong Park 0d047642eb Hide implementation details of log_time struct
In the future, the sizes of tv_sec and tv_nsec (or even the size of
log_time struct itself) can change due to the 32-bit overflow expected
to happen in the year 2138. In order to hide such implementation details
to the clients of liblog, the two macros LOG_TIME_SEC and LOG_TIME_NSEC
are introduced.

Furthermore, vendors are provided with a simplified version of log_time.h
without C++ APIs. In doing so, log_time.h no longer includes time.h.
This breaks several modules that implicitly relied on the hidden
dependency, which should be fixed.

Ian Elliott 58e06c5f94 Use void instead of no parameters in 2 function declarations.
In compiling some code with a picky "Android.mk" file, it is not happy
with a function declaration that looks like:

    void foo();

It requires:

    void foo(void);

This commit changes that for 2 functions in "log.h".

Mark Salyzyn 4d99c986d9 liblog: add LOGGER_STDERR frontend
Standalone, this logger provides no end-to-end capability.  Only
provides a writer, no reader transport.  All output goes, logcat-like,
into the stderr stream.  Output can be adjusted with environment
variables ANDROID_PRINTF_LOG and ANDROID_LOG_TAGS.

liblog_*.__android_log_bswrite_and_print___max print fails if a string
member is truncated with "Binary log entry conversion failed" and -1.
We expose the truncated content in the tests and in LOGGER_STDERR.

The purpose of this transport selection is for command-line tools,
providing a means to shunt the logs to be mixed in with the tool's
error stream.

- Create the local-only logger module

- Permit log reader for host compilation

android_set_log_frontend(LOGGER_LOCAL) will result in logs going
into application local memory.  logcat can not retrieve the data,
the user must utilize the log reading interface directly to
acquire their own logs.  Some local logger tests dropped as they
represent testing other liblog facilities.  Other local logger
tests dropped because we make the conscious decision to not
support LOG_ID_SECURITY logging.

ToDo: Some local logger tests dropped because of missing
      functionality associated with blocking reader.
