Subject: ui-shared: Remove needless cgit_get_cmd() call, and refactor hc()
 accordingly

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.

Subject: ui-shared: Replace ctx.qry.path with ctx.qry.vpath

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.

Subject: ui-shared: Display path limit directly beneath tab bar in relevant
 pages

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.

Subject: ui-shared: Teach "breadcrumb" navigation to path limit display
 beneath tab bar

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.

Also indicate in the comment section of the patch that a path limit was
applied, too easily see when a generated patch is only partial.

Subject: ui-commit: Preserve path limit in links to commit 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).

Subject: ui-shared: Preserve path limit in "tab bar" links

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.
