[PATCH/RFC 00/17] Begin gettextizing Git

Now that Git has the infrastructure for translation in next I'm going to start submitting patches to make the main porcelain translatable.

This series starts that work, and fixes and also fixes up some of the infrastructure (like the bug discussed in "Odd encoding issue with UTF-8 + gettext yields ? on non-ASCII"), and adds tests to make sure it's all working.

With it applied git-init is the one and only utility of the porcelain that's translatable. The series includes a translation of it into Icelandic and Polish.

I think it's ready to be applied. I tested it on Solaris, FreeBSD and Debian. But there's almost definitely something I'm missing in a series this big, so it's an RFC.
