Pull the bulk of the pre 2.0.0 changes from the git tree

For the most part, this was straight forward. For the very old
releases, there were lots of changes that are not straight forward
to untangle.

The following two releases posed issues:

 - Version 1.4.1 does not have a tag. The release tarball on FTP
   is from 2010-10-19 and appears to contain 1.4.0 with commit
   b864c387e8f16273aad1453d6457d847e29c3d25 cherry-picked on top
   of it (except for one line that was fixed in the release, but
   broken in the repo).

 - Version 1.4.6 also does not have a tag. The release tarball
   is from 2011-08-19. This _presumably_ corresponds with commit
   b602ab59b9782003d1179488d8c1580bc8563738 that bumps the version
   number.
