gitweb: Avoid overflowing page body frame with large images

When displaying a blob in gitweb, if it's an image, specify constraints for
maximum display width and height to prevent the image from overflowing the
frame of the enclosing page_body div.

This change assumes that it is more desirable to see the whole image without
scrolling (new behavior) than it is to see every pixel without zooming
(previous behavior).

transport-helper.c: do not overwrite forced bit

It does not necessarily mean the update was *not* forced, when the
helper did not say "forced update".  When the helper does say so, we
know the update is forced.

A workaround to fix breakage introduced by the previous step,
proposed by Max Horn.

notes: disallow reusing non-blob as a note object

Currently "git notes add -C $object" will read the raw bytes from $object,
and then copy those bytes into the note object, which is hardcoded to be
of type blob. This means that if the given $object is a non-blob (e.g.
tree or commit), the raw bytes from that object is copied into a blob
object. This is probably not useful, and certainly not what any sane
user would expect. So disallow it, by erroring out if the $object passed
to the -C option is not a blob.

The fix also applies to the -c option (in which the user is prompted to
edit/verify the note contents in a text editor), and also when -c/-C is
passed to "git notes append" (which appends the $object contents to an
existing note object). In both cases, passing a non-blob $object does not
make sense.

Also add a couple of tests demonstrating expected behavior.

Documentation: fix documentation AsciiDoc links for external urls

Turns out that putting 'link:' before the 'http' is actually superfluous
in AsciiDoc, as there's already a predefined macro to handle it.

"http, https, [etc] URLs are rendered using predefined inline macros."
http://www.methods.co.nz/asciidoc/userguide.html#_urls

"Hypertext links to files on the local file system are specified
using the link inline macro."
http://www.methods.co.nz/asciidoc/userguide.html#_linking_to_local_documents

Despite being superfluous, the reference implementation of AsciiDoc
tolerates the extra 'link:' and silently removes it, giving a functioning
link in the generated HTML. However, AsciiDoctor (the Ruby implementation
of AsciiDoc used to render the http://git-scm.com/ site) does /not/ have
this behaviour, and so generates broken links, as can be seen here:

http://git-scm.com/docs/git-cvsimport (links to cvs2git & parsecvs)
http://git-scm.com/docs/git-filter-branch (link to The BFG)

It's worth noting that after this change, the html generated by 'make html'
in the git project is identical, and all links still work.

stop using fnmatch (either native or compat)

Since v1.8.4 (about six months ago) wildmatch is used as default
replacement for fnmatch. We have seen only one fix since so wildmatch
probably has done a good job as fnmatch replacement. This concludes
the fnmatch->wildmatch transition by no longer relying on fnmatch.

Merge branch 'nv/commit-gpgsign-config' into jch

Introduce commit.gpgsign configuration variable to force every
commit to be GPG signed.  The variable cannot be overriden from the
command line of some of the commands that create commits except for
"git commit" and "git commit-tree", but I am not convinced that it
is a good idea to sprinkle support for --no-gpg-sign everywhere,
which in turn means that this configuration variable may not be
such a good idea.

  commit-tree: add and document --no-gpg-sign
  Add the commit.gpgsign option to sign all commits
