Reproducibility is here to stay and needs to be part of our default workflow.
Move the remaining code to base.bbclass so it is always a first class citizen
and it is clear people need to be mindful of it.

To try and avoid parse/memory overhead of functions within bitbake,
move the bulk of the reproducibility functions to the function library.

Ensure the fallback value if used is written to the SDE file
and hence stored in sstate, reducing any confusion within the
code over '0' values.
Bump the HASHEQUIV_VERSION since we've had a ton of trouble
with ensuring this rolls out correctly on the autobuilder so
others may too, take a clean slate for it.

This in particular addresses vulkan-samples reproducibility which made me scratch my
head for a while.

The check for a git HEAD still wasn't quite correct because it was using
the .git directory as the current working directory. Instead, it should
be passed as the --git-dir argument when running git. Running `git
rev-parse HEAD` in a .git directory with no HEAD reports 'HEAD' and
exits with success but then 'git log' will fail, which is not what we
want.

Fixes an error that occurs when attempting to get the timestamp of the
latest commit when there is no HEAD in the git repository. The easiest
way to trigger this condition is to use the 'subdir=' option when
specifying a 'git://' SRC_URI.

Moves most of the python code used for dealing with the source date
epoch to library code.
