Framwork: Add support for variable size pattern lockscreen (Part 1/2)

Part 2: http://review.cyanogenmod.org/#/c/28534/2

Forward port of: http://review.cyanogenmod.org/#/c/20613/

The default size has been replaced with a constant PATTERN_SIZE_DEFAULT=3
It now parses the longInt as a byte, no longer requiring a get/set Int function.
Negative numbers and sizes over 127 do not make sense, so a byte works well.
In addition the logging has been removed.

Patch Set 1-2: Initial port

Patch Set 3-5: New implementation using seperate file for non standard sizes

Patch Set 6: Use AOSP code style

Patch Set 7-9: Remove static code

Patch Set 10: Correct a comment
