[PATCH 0/6] Port git to Plan 9

I ported git, and git subcommands only written in C to Plan 9. This pull request contains patches for existing codes, and new files to build git in Plan 9.

All build options such as NO_PERL are not supported yet, and also some git subcommands written not in C is not available yet. But git can synchronize to remote repository with git pull and git push via HTTPS.

This pull request don't contain a part of Git toolchain for example git-credential-store, etc. So I'm going to port other parts of Git toolchain too in the future.
