[PATCH 00/13] mingw unicode environment

Hello,

this is the remainder of Karsten's unicode branch, that is a time proven part of msysGit. (If this code is accepted, only one patch would only remain: gitk and git-gui fixes.)

When rebasing Karsten's work, I have eliminated two commits: https://github.com/msysgit/git/commit/f967550 https://github.com/msysgit/git/commit/290bf81

These commits only moved code down and up; this was not necessary, one forward declaration was all I needed.

One of the patches differs from the original version: "Enable color..." Following Karsten's suggestion, I have changed the value of env. var. TERM from "winterm" to "cygwin". This is because the subprocesses see the variable and may try to find it in (their copy of) termcap.

Enjoy,
   Stepan
