Add two links to the "Diffstat" line to show more/less context lines in the
generated diff.
To support this, cgit_commit_link() and cgit_diff_link() has learned to
preserve the ctx.qry.context variable.

When using the commit-filter functionality to add e.g. bug tracker links to
commit messages, the style of those links is mangled by a CSS directive that
is meant to only apply to decorations that are listed on the commit-subject
line.
Fix this directive to only apply to the decorations.

When using the "tab bar" in the pageheader to navigate between pages, any
path limit in effect on the current page is forgotten in the link to the
target page, even if the target page can interpret and use the path limit
constructively.
Instead, preserve the current page's path limit in the "tab bar" links to
other pages, where the path limit is useful to the target page.

This includes adding a path argument to cgit_commit_link() and updating all
its callers. The callers from within the commit page (i.e. the "commit",
"unidiff"/"side-by-side diff" and "parent" links) all preserve the path
limit of the current commit page. All other callers pass NULL (i.e. no path
limit).

The path breadcrumb navigation at the top of the 'tree' page has now been
duplicated in ui-shared, which leaves the ui-tree implementation unnecessary.
This patch removes the breadcrumb navigation from ui-tree, and moves the
"(plain)" link that followed the breadcrumb when displaying blobs to the
end of the next line, following the blob SHA1.

When a path limit is in effect, and displayed directly beneath the tab bar,
it should offer breadcrumb navigation (like what the 'tree' page does), to
allow changing the path limit easily.
Implementing this requires a robust way to link back to the current page with
a changed ctx->qry.path, but without losing track of the other query
arguments. This is solved by adding the new cgit_self_link() function, which
is then invoked repeatedly by the new cgit_print_path_crumbs() function while
manipulating ctx->qry.path.

Design-wise, the path is shown by "expanding" the grey border between the
tab bar and the content area of the page to house the current path limit.
This is only displayed on pages where the path limit is relevant, and only
when a path limit is in effect.

In all cases where ui-shared uses ctx.qry.path, it is done so in the context
of a in-project path, and not in the context in which the 'refs' page or the
'clone'-related functionality uses ctx.qry.path. Make this explicit by using
ctx.qry.vpath instead.
This path introduces no fundamental difference in functionality except for
fixing some minor bugs, for example the Atom feed reference from a
"$repo/refs/heads/" page.
Note that the usage of ctx.qry.path in the other ui-<page>.c files is ok,
since that code presumably is only executed in the context of its own <page>,
so the correct interpretation of ctx.qry.path is never in question.

For many commands/pages (e.g. 'tree', 'diff', 'plain', etc.), the
ctx.qry.path argument is interpreted as a path within the "virtual" project
directory structure. However, for some other commands (notably 'refs', and
the clone-related commands) ctx.qry.path is used in a different context (as
a more or less "real" path within the '.git' directory).
This patch differentiates between these two usages of ctx.qry.path, by
introducing a new variable - ctx.qry.vpath - which is equal to ctx.qry.path
in the former case, and NULL in the latter.
This will become useful in future patches when we want various pages and the
links between them to preserve existing in-project paths.

The call to cgit_get_cmd() and the following fallback handling (to "summary"
or "repoindex") in cgit_print_pageheader() is unnecessary, since the same
fallback handling was already done when ctx.qry.page was set when
cgit_get_cmd() was called from process_request() in cgit.c.
As such, hc() can also be rewritten to simply compare the given 'page' string
against ctx.qry.page.

This patch teaches cgit to expand environment variables in certain
cgitrc option values (cache_root, scan-path, include) plus when
finding the location of cgitrc itself.
One use case for this feature is virtual hosting - e.g. by setting
$CGIT_CONFIG='/etc/cgitrc/$HTTP_HOST' in httpd.conf, all virtual
hosts automatically gets their own cgitrc.

The only valid characters for a URL are unreserved characters
a-zA-Z0-9_-.~ and the reserved characters !*'();:@&=+$,/?%#[] , as per
RFC 3986. Everything else must be escaped. Additionally, the # and
? always have special meaning, and the &, =, and + have special meaning
in a query string, so they too must be escaped. To make this easier,
a table of escapes is now used so that we do not have to call fmt() for
each character; if the entry is 0, no escaping is needed.

Git's read_tree_recursive() already filters out the objects by pathname,
so we only have to compare baselen to the expected. That is, no string
matching is required.
Additionally, if the requested path is a directory, the old code would
walk through all of its immediate children. This is not necessary, this
so we no longer do that.
