Add functions for parsing integers with size suffixes

Browse source 
Split out the nnn{k,m,g} parsing code from git_config_int into
git_parse_long, so command-line parameters can enjoy the same
functionality.  Also add get_parse_ulong for unsigned values.

Make git_config_int use git_parse_long, and add get_config_ulong
as well.
