[gentoo-soc] pomu weekly report for week #11

[Микита Голубаха]

This is the weekly report for the week of 07.08-13.08.

I continued work on the git remote fetcher, but some protocol limitations have rendered my work useless. I ended up scrapping it in its entirety, and instead rewrote the fetcher directly in pomu as a wrapper for the git command (and a few git object parsers), in addition, I wrote fetchers for each of the overlay types featured in overlays.xml: rsync, svn, mercurial (in addition to git), and a generic base for any possible alternative type. I'm a few steps away from a complete remote overlay backend.

The plan:
* add the zugaina package searcher
* integrate the remote fetcher backend
* finish up dep tree parser

Weekly commits (excl. late git-gg);
- Remote fetching
Added classes to fetch packages/trees etc. from remote repositories of
all kinds mentioned in overlays.xml: git, mercurial, svn, rsync
Added utility functions for git repos and to interact with filesystem
repository hierarchy
