* mail-on-sd: (40 commits)
Added more comments to explain how the locking mecanism works for LocalStore
Fixed wrong method being called during experimental provider initialization (since provider isn't enabled, that didn't harm)
Add more comments about how the various StorageProviders work and how they're enabled

French localization for storage related settings
Remove unused SD card strings (replaced with storage indirection)
Merge mail-on-sd branch from trunk
Reset mail service on storage mount (even if no account uses the storage, to be improved)

Migraion -> Migration
move the Storage location preference into preferences rather than the wizard.
Made LocalStore log less verbose Added @Override compile checks
Added ACTION_SHUTDOWN broadcast receiver to properly initiate shutdown sequence (not yet implemented) and cancel any scheduled Intent
Be more consistent about which SQLiteDatabase variable is used (from instance variable to argument variable) to make code more refactoring-friendly (class is already big, code extraction should be easier if not referencing the instance variable).
Added transaction timing logging
Factorised storage lock/transaction handling code for regular operations.
Use DB transactions to batch modifications (makes code more robust / could improve performances)
Merge mail-on-sd branch from trunk
Update issue 888 Added DB close on unmount / DB open on mount
Update issue 888 Back to account list when underlying storage not available/unmounting in MessageView / MessageList
...
Message retrieval:
- Use the given projection for the cursor result instead of always using a predefined projection. Extraction logic is now in dedicated classes for easy extension.
- Added BaseColumns._ID & BaseColumns._COUNT columns.
- Deprecated "id" column since it's not a reliable identifier (it's an incremential value generated at query() time)
Don't export the formatted date through the content provider: now exported as the raw Epoch value - date formatting is a UI concern. That makes MessageInfoHolder lighter.
Added semaphore to prevent third party content resolver from exhausting K-9 resources: it won't allow more than 1 cursor to be active at the same time. Concurrent threads (other content resolver invocations) will be suspended until the previous cursor gets released.
Removed dependency from K9 to MessageProvider (and added ability for components to register themselve for being notified when K9 instance is ready)
Moved Intent broadcast code from MessageProvider to K9
Made query() easily extensible using strategy pattern, the discriminant still being the Uri path
Fixed severe design flaw where the message provider would accumulate messages, causing an OutOfMemoryError even when the message provider isn't explicitely invoked.
query() is now synchronized with message retrieval
