Future commits will want to parse a double-precision floating point value from configuration, but we have no way to parse such a value prior to this patch. The core of the routine is implemented in git_parse_double(). Unlike git_parse_unsigned() and git_parse_signed(), however, the function implemented here only works on type "double", and not related types like "float", or "long double". This is because "float" and "long double" use different functions to convert from ASCII strings to floating point values (strtof() and strtold(), respectively). Likewise, there is no pointer type that can assign to any of these values (except for "void *"), so the only way to define this trio of functions would be with a macro expansion that is parameterized over the floating point type and conversion function. That is all doable, but likely to be overkill given our current needs, which is only to parse double-precision floats.
