[PATCH v6 0/4] config: add support for http.<url>.* settings

["Kyle J. McKay" <mackyle@gmail.com>]

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

Differences from v5:

Dropped the GIT_SSL_CERT_PASSWORD_PROTECTED patch.  It's related to the
http.sslCertPasswordProtected patch, but not required as it touches different
sections of the http.c file.

1/4 - this is identical to v5's 3/5.  Updated from v4's 1/4:

* Added cover comments to log message (feedback-jh)
* Updated help text (feedback-jk)
* Uppercased enum values (feedback-jk)
* Moved #ifdef enum values to end (feedback-jh)
* Renamed check_matched_len to new_match_is_shorter (feedback-jh)
* Removed 1 unnecessary cast (feedback-jk,feedback-jh)
* Based on preparatory http.sslCertPasswordProtected fix (feedback-jh)

2/4 - Updated from v5's 4/5:

* Altered append_normalized_escapes descriptive comments (feedback-es)
* Improved normalization (keep empty user name, strip port leading 0s and
  resolve . and .. in path)

3/4 - Updated from v5's 5/5:

* Add more tests and adjust to improved normalization behavior

4/4 - New code

* Allow a http.<url>.* config item without a user name to match a url passed
  to git that has a user name


Applicable comments from v5 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.
