[GSOC] Week 2: Unification of tag -l, branch -l and for-each-ref

Hello All,

As part of GSoC I'm working on the Unification of 'for-each-ref', 'tag -l'
and 'branch -l'. I will update the list on my weekly progress in an effort
to keep everyone updated.

Current Progress:
Currently I have two patches for review on the mailing list.

1. [PATCH v8 0/11] Create ref-filter from for-each-ref
(http://article.gmane.org/gmane.comp.version-control.git/271563)
This is basically related to the movement of code from for-each-ref to
ref-filter. ref-filter would act as a base for tag -l and branch -l. They can
eventually use the ref-filter APIs to implement the --format and --sort options
provided by ref-filter.

2. [PATCH v2 00/11] add options to for-each-ref
(http://article.gmane.org/gmane.comp.version-control.git/271575)
This relates to the addition of options like '--points-at',
'--merged', '--no-merged'
and '--contains' options to ref-filter and making use of these options
in for-each-ref
and implementing tests for the same.

Work in progress:
You can follow my current progress on Github:
https://github.com/KarthikNayak/git
Currently working on bringing tag.c on board and making it use the
ref-filter APIs and implement the various options provided by
ref-filter.
This might require an option of having ref-filter sort based on
version no when listing refnames.

Whats next:
After getting tag.c to work with ref-filter APIs. Start porting branch
-l to use ref-filter
APIs too.
