Convert flashrom to git

 - Drop support for Subversion in the getrevision script and Makefile.
 - Add .gitignore and .gitattributes file (the latter to limit exports).
 - Restore modification dates of the exported files from the SCM.
 - Stop exporting SCM log dumps to CHANGELOG. This makes no sense.
 - Do not export the pre-"compiled" manpage. It can be generated like
   anything else from the code dump when we export the respective
   The latter is added with this change.
 - Add some initial client-side git hooks
   * When committing check for obvious stuff you never want anyway:
     - white space errors
   * When pushing to the upstream repository check mandatory rules:
      - existing signoffs and acks in all new commits
      - no deletions or creation of branches
      - do not rewrite history of the precious branches, even if forced

NOTE: This patch is adapted from Stefan Tauner's original commit:

There are a few major differences:
- This uses coreboot's commit-msg hook which includes support for
  generating and appending Change-Id.
- djgpp-dos target removal is moved to a follow-up patch.
- Version string changes are moved to a follow-up patch.
