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.

None of the html_* functions modify their argument, so they can all be
'const char *' instead of a simple 'char *'. This removes the need to
cast (or copy) when trying to print a const string.

When a user requests a plain view of a tree (as opposed to a blob),
print out a directory listing rather than giving a 404 Not Found.
Also, fix a segfault when ctx->qry.path is NULL - i.e, when /plain is
requested without a path.

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.

Sometimes it is not feasible to generate the HTML pretty-print for large
files, especially if a source-filter is involved or binary data is to be
displayed. The "max-blob-size" config var allows to disable HTML output
for blobs bigger than X KBytes. Plain downloads are not affected.

The highlight tool can be given any of the supported file extensions
as its -S parameter. This patch replaces the case-switch by extracting
the extension from the supplied file name and passing it to highlight.
However, this requires a shell supporting the ${var##pattern} syntax,
like dash or bash.
Unknown extensions cause a fall-back to plain text using the --force
switch. Error messages are redirected to /dev/null.
A special case maps Makefile and Makefile.* to the "mk" extension.
The total overhead is reduced by calling "exec highlight". No forks are
needed during script execution.

Refuses to do so if the left hand side of the diff has different amount of
differing lines to the right hand side to avoid confusion.
Note that I use the naive dynamic programming approach for calculating the
longest common subsequence. We could probably be more efficient by using a
better algorithm. The LCS calculating function is O(n*m) and uses up n*m
amount of memory too (so if we we compare two strings of length 100, I use
an array of 10000 for calculating the LCS). Might want to not calculate LCS
if the length of the line is too large.
