When an unknown page is requested, either on the querystring or via
PATH_INFO, we end up with a null-referencing cgit_cmd. This null-
pointer is then used as argument to the hc() function (which decides
what tab to render as 'active'), but this function failed to check if a
valid cmd was specified and a SEGFAULT would occur. This patch fixes the
issue by introducing a 'fallback-cmd' which specifies what tab to render
as 'active' when no valid cmd is requested.
While at it, we now also keep track of the active repository even if an
invalid cmd was requested since we want to show the error message about
the invalid request in the correct context.

The 'h' querystring parameter in cgit is normally used to specify
a branch (i.e. a ref below refs/heads/), but if a repository contains
a tag with the same name as a branch the output from ui-log would use
the tag as start-revision.
This patch tries to fix the issue by checking if the specified ref is
valid as a branch name; if so, the full refname is used in the call
to setup_revisions().

When downloading a snapshot, the snapshot name will often contain the repo
name combined with a tag. This patch tries to exploit this so that the
correct revision is downloaded even if no specific revision is specified.
PS: this only occurs if neither 'h' nor 'id' is specified in the query-
string.
PPS: this also fixes a bug which occurs when trying to download a filename
with an unsupported suffix: it used to try to print an error message to
the user but failed since it didn't prepare the output properly.

This flag is set when no HEAD is specified in the querystring. Currently

In commit a1266edfe the build instructions for the git libs where moved
to their real targets, which in turn depended on the phony target `git`.
But since `git` is an actual directory in cgit the git libs wouldn't be
recompiled when needed.
So with this patch (third time lucky), cgit is declared to depend on the
really phony target `libgit` and the build instructions for `libgit` is
to unconditionally rebuild git/libgit.a and git/xdiff/lib.a.

When building cgit we depend on xdiff/lib.a and libgit.a in the git

failed since the build instructions for the libs was placed under the

This patch fixes the issue by moving the build instructions to their
real targets. It also makes it clear that only the `cgit` target
depends on the git binaries (since they're only used during linking).
