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 0.9.99-e4f6643 on Linux 3.13.0-76-generic (x86_64)

5 commits since last tag in upstream's stable branch:
flashrom 0.9.99-5-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 0.9.99-3-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 0.9.99-3-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) or local branch:
flashrom 0.9.99-3-e4f6643 on Linux 3.13.0-76-generic (x86_64)

No tags reachable from current commit (generic git fallback):
