SystemUI: prevent NPE on clear recents double press

Pressing Clear all button twice fast or while the list
is clearing but not yet fully cleared causes sysui to crash due to
mRecentTaskDescriptions being null: (http://pastebin.com/2gRFvf8k)

Workaround it by hiding clear all recents button.

Correct stride for drawing to cached glyph bitmap

fixes the glyph cachebuffer index to account for pixelbuffer
format size.

issue: in launcher home screen create icon group and rename the
group to some text string with emo-icons (smilies). without this
change the drop shadows for emo-icons will look bad.

Use alpha channel instead of red in drawCachedGlyphBitmap

the correct value to copy in bitmap is alpha component from
the cachebuffer. currently it is offset to red channel if format is
RGBA which is wrong.

this is followup fix for https://android-review.googlesource.com/#/c/93943/

MtpDatabase JNI: Fixed a memory-leak in getObjectPropertyValue().

The jstring "stringValue" was not never freed.
In the case where "str" was NULL the whole cleanup part (see "goto out")
was even skipped.
This patch makes getObjectPropertyValue() behave like
getObjectPropertyList().
