git-p4: add optional type specifier to gitConfig reader

The functions "gitConfig" and "gitConfigBool" are almost identical.
Make "gitConfig" more generic by adding an optional type specifier.
Use the type specifier "--bool" with "gitConfig" to implement
"gitConfigBool. This prepares the implementation of other type
specifiers such as "--int".
