views: add automatically constructed file location metadata
When constructing views, metadata is available about the location of the
file in the view's reference branch. Allows incorporating parts of the
directory hierarchy in a view.
For example `git annex view tag=* podcasts/=*` makes a view in the form
tag/showname.
Performance impact: I benchmarked git annex view tag=* in the conference
proceedings repo to take 6.459s before this change, and 6.544s after.
FWIW, I considered making the syntax for this be podcasts/*, which might
be easier for the user to learn. However, I think it's not as good:
* The user has to then juggle two different syntaxes, and podcasts/* will
be expanded by the shell so they also need to quote it, while podcasts/=*
is unlikely to be expanded by the shell.
* It would allow for things like podcasts/*/* and *.mp3 which do not
map well into views.
