Teach Git how to parse standard power of 2 suffixes.
Sometimes its necessary to supply a value as a power of two in a
configuration parameter. In this case the user may want to use the
standard suffixes such as K, M, or G to indicate that the numerical
value should be multiplied by a constant base before being used.
Shell scripts/etc. can also benefit from this automatic option
parsing with `git repo-config --int`.
