The return values of these functions are essentially constant and should
never be modified.
Note that this will introduce a compiler warning when we try to free the
return value of any of these functions. However, given that all of these
currently return statically allocated strings in some cases, they need
to be refactored before this can be done anyway.

Since tail is initialized to 0, we will never get a warning on the last
if statement, but recent gcc complains anyway. So, we initialize len as
well. Future gcc versions should be able to optimize this out anyway.
cgit_self_link() is a void function but implements each case it handles
by doing "return <another_void_function>" which is not valid C; section
6.8.6.4 of C11 says:
A return statement with an expression shall not appear in a
function whose return type is void.
Fix this by removing the return keywords and converting the final code
block into an "else".

When a repository is empty, the ATOM feed link is written in the header,
but this involves formatting ctx->qry.head which is NULL in this case.
With glibc, vsnprintf formats "%s" with a NULL input as "(null)" but on
Solaris this results in a segmentation fault. Since we don't have a
meaningful head for the atom feed in an empty repository, it's simplest
not to write out the link element at all.

When the repolist is paged, the page-links are missing the sort parameter,
causing the initial page to be custom sorted, but any clicked page will
then be with the default sort order again.
The current 'repo.module-link' option is sufficient when all gitlinks
in a repository can be converted to commit links in a uniform way, but
not when different submodules/paths needs different settings.
This patch adds support for 'repo.module-link.<path>', which will be
used for linking to submodules at paths matching one such entry.

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).

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.

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.

When embedded=1, cgit used to ignore the header and footer options.
But honoring these options when embedded=1 makes it possible to "frame"
the html fragment generated by cgit with any kind of static content,
i.e. it should become easier to integrate cgit with site-specfic
layouts.

cgit_print_http_headers() used to do nothing if 'embedded' was
specified in cgitrc, but that was wrong - we never want to skip the
headers when invoked as a CGI app. Sadly, there's no easy way to
detect if we're invoked as a CGI app or if we're invoked by another
CGI app, so for the latter case cgit needs to be invoked with either
--nohttp on the command line or NO_HTTP=1 in the environment.
