Add conditions to check for updated system applications. Restrict them 

to internal flash only even before we copy.

Return error codes when install flag options mismatch.
Some conditions for existings apps
 - install flags override existing location
 - explicity manifest option install location overrides previous location
 - if upgraded package's install location is unspecified or auto, fall
   back to recommended install policy which considers user setting as well.

Check for sdcard status before finding available size on sdcard
Add light weight parsing for manifest attributes including package name and
install location only
