Ensure build deps are consistent across the spec file and test harness.
Note: http://fedoraproject.org/wiki/HOWTOFindMissingBuildRequires
says that some packages should not be BuildRequires because
"they would occur too often" and "are considered the minimum build
environment." However, Docker changes the scope of that assumption
to keep docker images small.
* asciidoc indirectly requires docbook-style-xsl on el6 and f20,
but not on el5. Resolve failure to build tito with tito on el5:
"I/O error : Attempt to load network entity"
* Resolve "egg missing file" on el5 due to busted symlinks
from 20c4f1b7c0.
* Add functional test to build tito with itself in order to
catch problems like the ones above.
Closes https://github.com/dgoodwin/tito/issues/133
Older versions of git-annex don't support `git annex lock --force`, so peform
a version check and call without --force on these.
The EL6 Docker image is changed to one that contains locales, in order for
git-annex to run successfully.
Add URL of upstream tito repo to HACKING, then
symlink HACKING as README.md in each Dockerfile dir.
Why?
If a README.md exists in same dir as Dockerfile (incl. symlink),
and it's set up as a
[trusted build](https://index.docker.io/help/docs/#trustedbuilds),
then index.docker.io automatically shows the readme on the info
page of the trusted build.
