app ops: New ops, features, and modes

AppOpsService: Add MODE_ASK support to AppOps.

Add support for new mode(MODE_ASK) in AppOpsService to show a permission
dialog box to user to confirm user permission before allowing or ignoring
that operation.

All strict operations (defined in AppOpsManager) are going to be in
MODE_ASK by default.

Operations will be moved to MODE_ALLOWED or MODE_IGNORED according to
user's choice.

AppOps: Add support for whitelist of packages.

By default AppOps gives MODE_ASK permission to all strict operations.
This can degrade user experience for pre-installed apps.

This change adds support for passing a whitelist XML file to AppOps.
Operations requested by packages listed in whitelist file will be set
to MODE_ALLOWED by default.

User can still go into settings and override permissions of these
operations.

Whitelist XML file should have following format:
Example: whitelist_appops.xml

<whitelist-pkgs>
    <pkg name="com.android.settings"/>
    <pkg name="com.android.systemui"/>
    .
    .
    .
</whitelist-pkgs>

AppOpsManager: set default mode for sms write operation to MODE_ALLOWED.

The default mode for sms write operation is set to
MODE_IGNORED, so this was not allowing Bluetooth Map application
to do any write operation of SMS. So set the default mode to
MODE_ALLOWED.

Fix for positioning of glyphs within a bitmap

For positioning of glyphs within a bitmap, roundf(int + float) is used,
where the float is the glyph position and the int is the text position.
When the text position is varied, this may lead to the sum being rounded
in different directions, due to floating point rounding, caused by that
floating point numbers have different precision in different ranges.

This may therefore lead to slightly different positioning for glyphs and
therefore slightly different widths and heights for text strings,
depending on the position they are rendered at.

The solution in this patch is to use int + (int) roundf(float), which
has consistent rounding, and also enables us to use the full range of
ints.

Release locked buffer when it fails to acquire graphics buffer

The JNI buffer in ImageReader_imageSetup is not released when
it fails to acquire graphics buffer. After all JNI buffers are
exhausted, ACQUIRE_MAX_IMAGES will be returned and leads to
error. The JNI buffer should be released when it fails to acquire
graphics buffer.

a FOTA update.

Fix graphics corruption caused by HWUI caches

Some caches(PatchCache, TextureCache, PathCache) for HWUI
uses deferred removal for their cache entries even though
actual resource objects are immediately freed by
ResourceCache.
For this reason, the uniqueness of a resource address in
the caches is not guaranteed in specific cases.
(Because malloc() can return the same address when malloc()
and free() called very frequently.)

So it can be possible the cache have two cache entries for
two different resources but the same memory address.
(Of course one of the resources is already freed.)
It also can be possible mGarbage vector in PatchCache has
duplicated addresses and this can lead to duplicated free
blocks in the free block list and graphics corruption.
(Deferred removal was implmeneted based on an assumption of
unique resource addresses.)

So this patch makes sure resource objects are freed after
the resources are removed from the caches to guarantee
the uniqueness of a resource address and prevent graphics
corruption.
