[PATCH v6 0/6] http.<url>.<key> and friends

This is my attempt to reroll Kyle's http.<url>.<key> series.

It adds a general <section>.<url>.<key> support at the infrastructure level and then rebuild http.<url>.<key> support on top of it. A useful side effect of doing it this way is that it avoids having to touch the two-name parser http_options() at all.

The same infrastructure is used to add "--get-urlmatch" mode to "git config", so that scripted Porcelains can use the same mechanism to ask for the value for <section>.<key> variable with a URL, and learn the value for <section>.<url>.<key> whose <url> part best matches the given URL. In a sense, the infrastructure makes <section>.<key> a "virtual" variable that is customized for URL.

 * Patch 1/6 is unchanged.

 * Patch 2/6 is to add only the two helpers url_normalize and
   match_urls from the original series by Kyle.

 * Patch 3/6 is the general <section>.<url>.<key> support.  The
   urlmatch_config_entry() wrapper can use existing two-name parser
   to implement "virtual" <section>.<key> variables.

 * Patch 4/6 is the rest of Kyle's http.<url>.<key> ported on top of
   the infrastructure.

 * Patch 5/6 is unchanged from the previous round.

 * Patch 6/6 teaches "--get-urlmatch" to "git config"; this time it
   adds tests and docs.

Junio C Hamano (4):
  http.c: fix parsing of http.sslCertPasswordProtected variable
  config: add generic callback shim to parse section.<url>.key
  builtin/config: refactor collect_config()
  config: "git config --get-urlmatch" parses section.<url>.key

Kyle J. McKay (2):
  config: add helper to normalize and match URLs
  config: parse http.<url>.<variable> using urlmatch
