* Package file parsing - fixed size and isize - isize is the "size" variable

Browse Source 
from the PKGINFO, and size is the stat() size of the archive
* Removed the useless 'output' param from package.c:parse_descfile
* Installation progress
  - Call progress callback once at 0% for initialization
  - 'needdisp' was useless
  - alpm_list_count is called an excessive amount in these nested loops.  Now we
    only call it once per iteration
  - Use the compressed sizes for PROGRESS calcs as uncompressed (isize) is not
    exact (it is missing metadata sizes), and thus produces > 100% numbers
