setup: use changes since latest tag instead of just distance
For a Mercurial built on the merge from stable into default right after 3.2.2
was released -- 19ebd2f88fc7 -- the version number produced was "3.2.2+4". This
is potentially misleading, since in reality the built Mercurial includes many
more changes compared to 3.2.2.
Change the versioning scheme so that we take into consideration all the changes
present in the current revision that aren't present in the latest tag. For
19ebd2f88fc7 the new versioning scheme results in a version number of
"3.2.2+256". This gives users a much better idea of how many changes have
actually happened since the latest release.
Since changessincelatesttag is always greater than or equal to the
latesttagdistance, this will produce version numbers that are always greater
than or equal to the old scheme. Thus there's minimal compatibility risk.

The number of possible cases is significant but they but they all have a slightly different handling. So this section commits to and testing all of them to allow safe refactoring of the revert code. A python script is used to generate a file history for each combination of states, on one side the content (or lack thereof) in two revisions, and on the other side, the content and "tracked-ness" of the working directory. The three states generated are: - a "base" revision - a "parent" revision - the working directory (based on "parent") The files generated have names of the form: <rev1-content>_<rev2-content>_<working-copy-content>-<tracked-ness> All known states are not tested yet. See inline documentation for details. Special cases from merge and rename are not tested by this section.
