[PATCH/RFC 04/11] compat: add inet_pton and inet_ntop prototypes

[Erik Faye-Lund <kusmabite@googlemail.com>]

From: Mike Pape <dotzenlabs@gmail.com>

Windows doesn't have inet_pton and inet_ntop, so
add prototypes in git-compat-util.h for them.

At the same time include git-compat-util.h in
the sources for these functions, so they use the
network-wrappers from there on Windows.
