GC: Improve the string parsing for GC parameter setting

Improve the string parsing for GC parameter system property.
Previously we only recoganize plain number for dalvik.vm.heapminfree
and dalvik.vm.heapconcurrentstart, while users tend to use format as
2m.  Improve the string parse to cover such cases.

Merge "base: Add theme support to Ringtone and Profile pickers activities" into cm-11.0
bootanim: Add continuous splash support

 * We may or may not want to have a very smooth transition from the
   bootloader into Android by way of a continuous splash feature.
 * Add a compile-time flag which disables the initial screen clearing
   so that we don't drop a frame during the transition.
