Change subject: This is a combination of 2 commits. The first commit's message is:
......................................................................

This is a combination of 2 commits.
The first commit's message is:

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.
 - Remove djgpp-dos target (it is not different to other x-compilations).
 - Do not export the pre-"compiled" manpage. It can be generated like
   anything else from the code dump when we export the respective variable.
   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
     - duplicate sign-offs
   * 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
 - Change version string of flashrom as follows.
   Previously, we included the last stable version according to a hard-
   coded string in the Makefile and appended the subversion revision number.

With this patch the version string includes the last reachable git tag,
   number of commits since said tag in the upstream branches (if any),
   the name of said upstream branch, number of commits since that branch
   (if any), and the shortened git hash.
   In case there are uncommitted changes a "-dirty" indicator is also added.
   The case of unknown versions is explicitly handled in getrevision instead
   of simply appending "-unknown" to a hardcoded release number.

The version information is either taken from an existing git remote
   pointing to an upstream repository (or a known mirror), or if that
   is not available - with the user's consent - a shadow copy is fetched
   from the upstream repo that is updated on every build (usually takes
   less than a second).

In the following some examples of the version string changes are shown.
Basically we print the distance to the last known upstream tag, which
comprises any upstream commits since that tag as well as local commits on
top of that. Additionally we handle upstream's stable and staging branches
specially.

Old output:
flashrom v0.9.7-r1716 on Linux 3.8.0-6-generic (x86_64)

New output variants:

Build of the 0.9.99 release without any changes:
flashrom v0.9.99-e4f6643 on Linux 3.13.0-76-generic (x86_64)

5 commits since last tag in upstream's stable branch:
flashrom v0.9.99-5-stable-e4f6643-dirty on Linux 3.13.0-76-generic (x86_64)

3 commits since last tag in upstream's staging branch and
4 local commits on top of that:
flashrom v0.9.99-3-staging-4-e4f6643 on Linux 3.13.0-76-generic (x86_64)

3 commits since last tag in upstream's staging branch and
4 local commits on top of that, and some local uncommitted changes too:
flashrom v0.9.99-3-staging-4-e4f6643-dirty on Linux 3.13.0-76-generic (x86_64)

3 commits since the last tag in an unrelated upstream branch
(e.g., a stable release *branch* such as 0.9.99.x) or local branch:
flashrom v0.9.99-3-e4f6643 on Linux 3.13.0-76-generic (x86_64)

No tags reachable from current commit (generic git fallback):
flashrom d95935a version on Linux 3.13.0-76-generic (x86_64)

Not in a repository:
flashrom unknown version on Linux 3.13.0-76-generic (x86_64)

This is the 2nd commit message:

Use standard git commit-msg hook

This replaces commit-msg hook with the standard one so that
Change-Ids are generated.

We could merge the one which was being used which detects multiple
lines beginning with "Signed-off-by", however I wanted to check with
the author first due to licensing of the standard hook (Apache 2.0).
