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/.

Currently used clang tidy does not filter the warnings caused
by macros, even if macros come from filtered headers.
This change allows projects using ALOGV to use
readability-implicit-bool-conversion without spreading //NOLINT everywhere.

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.

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
- Add LOGGER_LOCAL flag to android_set_log_frontend to enable
- 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.

Because the database can now be dynamic, we added reader/writer locks
which adds a 65ns (uncontended) premium on lookups, and switch to
check for an allocation adds 25ns (either open code, or using
string_view, no difference) which means our overall speed takes 90%
as long as the requests did before we switched to unordered_map.
Faster than before where we originally utilized binary lookup on
static content, but not by much. Dynamic updates that are not cached
locally take the following times to acquire long path to logd to
generate.

The long path pickups are mitigated by the built-in caching, and
the public mapping in /dev/event-log-tags.

Moved headers from include/libcutils and include/liblog to
libcutils/include and liblog/include respectively, so they can be
exported via these libs. They needed to be moved since Soong does
not allow export from external folder.
Added symlink from old locations. They are needed since Soong
includes system/core/include by default. Once all modules are
cleaned up to explicitly add the required libs, the symlinks will be
removed.
Also added liblog_vndk_headers that exports a special log/log.h for
VNDK.
Moved headers of libcutils to libcutils_headers. They should be used
by modules for header-only inlines. Added libcutils_headers as
dependency of libcutils.
Added libcutils_vndk_headers that exports a special cutils/log.h
deprecating usage of the file. A later CL will deprecate the one in
libcutils_headers
Test: Add above libs to shared lib of local module
