The static analyzer is concerned about the strcpys below this, since it
apparently doesn't try to model snprintf's potential behaviors. (In
particular, it was concerned that suffixLen might be >=
sizeof(suffixBuf)). While that's clearly suboptimal, this code can also
be simplified to make it more obvious what's happening and to appease
the analyzer.
No functionality change is intended.

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

Furthermore, vendors are provided with a simplified version of log_time.h

event_log_tag parser complains about a period (.) in the name,
we would consider such an enhancement to the tag names possible.
I expect we would want to be able to support alphanumerics,
underscore (_), period (.), minus (-), at (@) and comma (,) for
starters as they are present in the other text log buffer tags.
We introduce a local endOfTag function that is used during parsing and
during android_lookupEventTagNum for submitting new tags. This
function caused us to enforce const char more closely. By filtering
in both places we resolve an issue that could have plagued us if
garbage requests were made.

This code was supposed to be deprecated in time. Let's make it more
efficient and add QC_RIL prefix to the list of catches to redirect
from the main logs to the radio logs.

We would experience failures as test runs interfere with each other.
Create a unique tag for each test run signature. Switch from using
TEST_PREFIX to TEST_LOGGER to identify the logger transport being
inspected and make that part of the signature. Make sure 32 bit and
64 bit tests do not interfere.

- __security test to allow 20ms resting time after setting ro.device_owner
- enoent test resort to using "su" command if we are not root to start
and stop the logger.
- Add some instrumentation to guide us in the future if issues.

We still do not have any users of the 'frontend' interface, let's
right a wrong and rename it to 'transport' as it makes more sense.
Renames android_log_set_frontend, android_log_get_frontend and
include/log/log_frontend.h.

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.

android_log_processBinaryLogBuffer and android_log_processLogBuffer
error return should have message and messageLen fields set to zero,
or to a valid-but-truncated buffer so that we can discern the
difference. This will resolve an issue with reporting content from
an uninitialized field in liblogcat should caller add --debug flag.
To enhance the debugging capability, truncated string events because
of the logger limits are provided rather than dropping the field, but
still with an error return.
Some minor coding style issues resolved. Add required, or remove
extraneous spaces. Use C-style comments only.

Deal with cache miss in the event tag map resources and switch to
"Plan B" to ask long-path to logd for a determination on the tag,
name and format.
logcat-unit-tests liblogcat.descriptive does an under-the-hood call
to logd to add a new logtag but the in-process mapping fails to
pick it up because the /dev/event-tag-map map is SHARED PRIVATE for a
few moments to garner some (linux) efficiency with other copies that
are in the process. Without the workaround of marking the mapping
dirty to be reread, we are using this change as the proper workaround
that fixes the later parts of this test.
