* Add Kotlin, NDK, Protoc, Asm, and other new patterns.
* Put all clang-analyzer warnings to the ANALYZER severity group.
Some security and null pointer warnings still have HIGH severity.
* Comment out old C/C++ warnings that overlap with analyzer
warnings and do not appear in current build.log.
* Other old fixed warning patterns should be commented out later.

* When processing a downloaded build.log file,
find_android_root is very slow because the
android source tree is not found.
Change it to look for warn.py only up to 100 times,
and then set android_root to the longest common path prefix.

find_android_root works only when warn.py is found
so it works for build bot, but not when warn.py is
run against a stand alone build.log file.

if it is found.

While we are generating the html file also expose a way for a user to
save off a csv file. This prevents having to run the tool twice.
* Add a new flag called csvpath that takes a file path for the csv dump.
* Use csv.writer to simply print formats.
* Modify the dump_csv and count_severity to take a csv writer.
Test: run with a build.log file, compare before and after html/csv dumps.

* Allow other callers of this module to:
* pass any input stream to parse_input_file,
* pass any warning_lines to parallel_classify_warnings,
* call dump_csv or dump_html to get output.
* No output change.
* Capture and ignore signal.SIGTERM at the end,
to avoid bad warning/error messages from the exit clean-up process.
Test: run warn.py build.log.

Purpose of this change is not to save some execution time,
but to avoid forking another process. In other applications
that use a wrapper to call this python script, it is difficult
to get overwritten file I/O functions work in a subprocess.
So the wrapper will call warn.py with --processes=1.
Test: run "warn.py --processes=1 build.log"
Change-Id: I5998d5c70d81a456c86eb4002f444a4a60135477
* Add a --processes flag to specify number of parallel processes,
with default multiprocessing.cpu_count().
* Wrap long line to suppress pylint warning.

These projects are all used by RenderScript, but it would be good to
differentiate warnings for each.

* Warning messages must start with source file path.
This will reject lines containing only 'warning:'
but not a source file path prefix.

dump of strings to JavaScript string literals.

This was printing "error:", but not actually triggering an error.
Instead of trying to write a single line bash script to handle this,
move the actual check into python. This allows us to print all of the
errors for a single module before triggering the failure.
Also updates the warning format and the warn.py script to properly parse
these warning. Many of the java:sdk -> java:platform warnings are false
positives due to the lack of LOCAL_SDK_VERSION markings on prebuilts.
Individual tags can be marked as warnings now, which lets us check for
system libraries linking against vendor libraries (which won't work on
AOSP). I'm not sure this is a completely valid check, which one reason
that it's just a warning.
Test: m all_link_types (with some missing libs commented out)

and default table style for new warning count table.
* Count total skipped warnings.
* Append count of warnings in each severity header.
* Fix some skipped warning patterns and count/dump skipped warnings.

error when --byproject flag is used and severity.SKIP
is not emitted.
* Minor coding style changes:
* Loop through severity.kinds.
* Remove unused import.
* Add spaces around assignment operators.
