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.

Proper security labeling of multi-user data directories.

This patch covers 2 cases. When an app is installed
and the resulting data directory is created for all
existing users. And when a new user is created and
all existing app data directories are created for
the new user.
