Patrick Steinhardt af99049ca9 urlmatch: include host in urlmatch ranking
In order to be able to rank positive matches by `urlmatch`, we inspect
the path length and user part to decide whether a match is better than
another match. As all other parts are matched exactly between both URLs,
this is the correct thing to do right now.

In the future, though, we want to introduce wild cards for the domain
part. When doing this, it does not make sense anymore to only compare
the path lengths. Instead, we also want to compare the domain lengths to
determine which of both URLs matches the host part more closely.

Patrick Steinhardt 3ec6e6e8a0 urlmatch: split host and port fields in `struct url_info`
The `url_info` structure contains information about a normalized URL
with the URL's components being represented by different fields. The
host and port part though are to be accessed by the same `host` field,
so that getting the host and/or port separately becomes more involved
than really necessary.

To make the port more readily accessible, split up the host and port
fields. Namely, the `host_len` will not include the port length anymore
and a new `port_off` field has been added which includes the offset to
the port, if available.

The only user of these fields is `url_normalize_1`. This change makes it
easier later on to treat host and port differently when introducing
globs for domains.

Junio C Hamano 836b6fb5a5 config: add generic callback wrapper to parse section.<url>.key
Existing configuration parsing functions (e.g. http_options() in
http.c) know how to parse two-level configuration variable names.
We would like to exploit them and parse something like this:

	[http]
		sslVerify = true
	[http "https://weak.example.com"]
		sslVerify = false

and pretend as if http.sslVerify were set to false when talking to
"https://weak.example.com/path".

Introduce `urlmatch_config_entry()` wrapper that:

 - is called with the target URL (e.g. "https://weak.example.com/path"),
   and the two-level variable parser (e.g. `http_options`);

 - uses `url_normalize()` and `match_urls()` to see if configuration
   data matches the target URL; and

 - calls the traditional two-level configuration variable parser
   only for the configuration data whose <url> part matches the
   target URL (and if there are multiple matches, only do so if the
   current match is a better match than the ones previously seen).

Kyle J. McKay 3402a8dc48 config: add helper to normalize and match URLs
Some http.* configuration variables need to take values customized
for the URL we are talking to.  We may want to set http.sslVerify to
true in general but to false only for a certain site, for example,
with a configuration file like this:

	[http]
		sslVerify = true
	[http "https://weak.example.com"]
		sslVerify = false

and let the configuration machinery pick up the latter only when
talking to "https://weak.example.com".  The latter needs to kick in
not only when the URL is exactly "https://weak.example.com", but
also is anything that "match" it, e.g.

	https://weak.example.com/test
	https://me@weak.example.com/test

The <url> in the configuration key consists of the following parts,
and is considered a match to the URL we are attempting to access
under certain conditions:

  . Scheme (e.g., `https` in `https://example.com/`). This field
    must match exactly between the config key and the URL.

  . Host/domain name (e.g., `example.com` in `https://example.com/`).
    This field must match exactly between the config key and the URL.

  . Port number (e.g., `8080` in `http://example.com:8080/`).  This
    field must match exactly between the config key and the URL.
    Omitted port numbers are automatically converted to the correct
    default for the scheme before matching.

  . Path (e.g., `repo.git` in `https://example.com/repo.git`). The
    path field of the config key must match the path field of the
    URL either exactly or as a prefix of slash-delimited path
    elements.  A config key with path `foo/` matches URL path
    `foo/bar`.  A prefix can only match on a slash (`/`) boundary.
    Longer matches take precedence (so a config key with path
    `foo/bar` is a better match to URL path `foo/bar` than a config
    key with just path `foo/`).

  . User name (e.g., `me` in `https://me@example.com/repo.git`). If
    the config key has a user name, it must match the user name in
    the URL exactly. If the config key does not have a user name,
    that config key will match a URL with any user name (including
    none), but at a lower precedence than a config key with a user
    name.

Longer matches take precedence over shorter matches.

This step adds two helper functions `url_normalize()` and
`match_urls()` to help implement the above semantics. The
normalization rules are based on RFC 3986 and should result in any
two equivalent urls being a match.
