[PATCH v2 0/6] Rewrite `git_config()` using config-set API

[PATCH V2]: All the suggestions in [2] incorporated. git_config() now follows
	correct parsing order. Reordered the patches. Removed xfuncname patch
	as it was unnecssary.

This series builds on the top of 1d2856f (ta/config-set) in pu or topic[1] in the mailing list with name "git config cache & special querying API utilizing the cache".

This series aims to do these three things,

* Use the config-set API to rewrite git_config().

* Solve any legacy bugs in the previous system while at it.

* To be feature complete compared to the previous git_config() implementation,
  which I think it is now. (added the line number and file name info just for
  completeness)

Also, I haven't yet checked the exact improvements but still as a teaser, git status now only rereads the configuration files twice instead of four times.
