[PATCH v7 0/4] config: add support for http.<url>.* settings

NOTE: This patch requires the following preparatory change:

 f1ff763 http.c: fix parsing of http.sslCertPasswordProtected variable

which is currently in pu.

This patch series adds support for http.<url>.* settings. The patch is organized as a series of improvements on the functionality:

1/4 - adds basic textual matching support 2/4 - adds URL normalization before matching 3/4 - adds a test for the URL normalization function 4/4 - adds any user matching

With-Feedback-From-jh: Junio C Hamano <gitster@pobox.com>

Differences from v6:

1/4 - Updated from v6's 1/4:

* Added an http_init memset for http_option_max_matched_len (feedback-jh)

2/4 - Updated from v6's 2/4:

* Reduce use of strchr (feedback-jh)
* Correctly handle characters with high bit set during normalization
* Detect some additional invalid scheme names

3/4 - Updated from v6's 3/4:

* Add several additional tests for high bit set characters and invalid schemes

4/4 - Updated from v6's 4/4:

* Added an http_init memset for http_option_user_matched (feedback-jh)

Applicable comments from earlier cover:

To better support matching URLs that are equivalent but spelled differently, a url_normalize function has been added. Currently this patch leaves it in http.c as http_options_url_normalize as I am unclear whether it should go into url.{h,c} at this time since only http.c uses it.

Since the url_normalize function's behavior is non-trivial, it is presented as a separate patch on top of the basic http.<url>.* settings support. A new test for it has also been included as a separate patch. I am unclear on the proper number for this test, but have gone ahead and put it with the other http tests since this patch series places the url_normalize function into http.c.
