LookupCacheV4::Has implements safebrowsing v4 caching logic.
1. Check if fullhash match any prefix in local database:
- If not, the URL is safe.
2. Check if prefix is in the cache(prefix is always the first 4-byte of
the fullhash, Bug 1323953):
- If not, send fullhash request
3. Check if fullhash is in the positive cache:
- If fullhash is found and it is not expired, the URL is not safe.
- If fullhash is found and it is expired, send fullhash request.
4. If fullhash is not found, check negative cache expired time:
- If negative cache time is not expired, the URL is safe.
- If negative cache time is expired, send fullhash request.

This patch includes following changes:
1. nsUrlClassifierHashCompleter.js
nsUrlClassifierHashCompleter.idl
- Add completionV4 interface for hashCompleter to pass response data to
DB service.
- Process response data includes negative cache duration, matched full
hashes and cache duration for each match. Full matches are passed through
nsIFullHashMatch interface.
- Change _requests.responses from array contains matched fullhashes to
dictionary so that it can store additional information likes negative cache
duration.
2. nsUrlClassifierDBService.cpp
- Implement CompletionV4 interface, store response data to CacheResultV4
object. Expired duration to expired time is handled here.
- Add CacheResultToTableUpdate function to convert V2 & V4 cache result
to TableUpdate object.
3. LookupCache.h
- Extend CacheResult to CacheResultV2 and CacheResultV4 so we can store
response data in CompletionV2 and CompletionV4.
4. HashStore.h
- Add API and member variable in TableUpdateV4 to store response data.
TableUpdate object is used by DB service to pass update data or gethash
response to Classifier, so we need to extend TableUpdateV4 to be able
to store fullHashes.find response.
6. Entry.h
- Define the structure about how we cache fullHashes.find response.

This patch fixes that Classifier::ActiveTables doesn't return v4 tables.
Classifier::mActiveTablesCache is generated by scanning safebrowsing directory.
We use Classifier::ScanStoreDir to do the work, but it will ignore subdirectory.
Since v4 tables are stored in subdirectory 'google4', mActiveTablesCache doesn't
include v4 tables.
Fix this issue by checking subdirectory recursively in ScanStoreDir.

We add a new "on-off" protocol PURLClassifierLocal which calls
nsIURIClassifier.asyncClassifyLocalWithTables on construction and
calls back on destruction. Pretty much the same design as PURLClassifier.
In order to avoid code duplication, the actor implementation is templatized
and |MaybeInfo| in PURLClassifier.ipdl is moved around.
Test case is included and the custom event target is not in place for labelling.
The custom event target will be done in Bug 1353701.

I'm adding a helper function mozILocaleService::GetRequestedLocale to simplify
most of the callsites that are looking for the first of the requested locales.
In most cases, I'm just matching the behavior of the code with reusing
LocaleService API instead of direct manipulation on the prefs.
That includes how I handle error case scenarios.
In case of sdk/l10n/locale.js I am reusing LocaleService heuristics over
the custom one from the file since the ones in LocaleService are just
more correct and unified accross the whole platform.
In case of FallbackEncoding I have to turn it into a nsIObserver to listen
to intl:requested-locales-changed.

The Flash block tests sometimes timeout in debug runs. So far it has always happened the same way. All assertions in the test run (and pass), but the test times out during cleanup. Bumping up the timeout for these tests should fix this problem.
