When "git push" is run without any refspec (neither on the
command line nor in the config), we used to push "matching refs"
in the sense that anything under refs/ hierarchy that exist on
both ends were updated. This used to be a sane default for
publishing your repository to another back when we did not have
refs/remotes/ hierarchy, but it does not make much sense these
days.
This changes the semantics to push only "matching branches".

* jc/remote:
git-push: Update description of refspecs and add examples
remote.c: "git-push frotz" should update what matches at the source.
remote.c: fix "git push" weak match disambiguation
remote.c: minor clean-up of match_explicit()
remote.c: refactor creation of new dst ref
remote.c: refactor match_explicit_refs()
Refspecs with no colons are left with no dst value, because they are
interepreted differently for fetch and push. For push, they mean to
reuse the src side. Fix this for patterns.

There are only a dozen or so uses of strdup in all of git.
Of those, most seem ok, but this one isn't:

Earlier, when the local repository has a branch "frotz" and the
remote repository has a tag "frotz" (but not branch "frotz"),
"git-push frotz" mistakenly updated the tag at the remote side.
This was because the partial refname matching code was applied
independently on both source and destination side.
With this fix, when a colon-less refspec is given to git-push,
we first match it with the refs in the source repository, and
update the matching ref in the destination repository.

When "git push A:B" is given, and A (or B) is not a full refname
that begins with refs/, we require an unambiguous match with an
existing ref. For this purpose, a match with a local branch or
a tag (i.e. refs/heads/A and refs/tags/A) is called a "strong
match", and any other match is called a "weak match". A partial
refname is unambiguous when there is only one strong match with
any number of weak matches, or when there is only one weak match
and no other match.
However, as reported by Sparse with Ramsay Jones recently,
count_refspec_match() function had a bug where a variable in an
inner block masked a different variable of the same name, which
caused the weak matches to be ignored.
This fixes it, and adds tests for the fix.

When checking what ref the source refspec matches, we have no
business setting the default for the destination, so move that
code lower. Also simplify the result from the code block that
matches the source side by making it set matched_src only upon
unambiguous match.

This refactors open-coded sequence to create a new "struct ref"
and link it to the tail of dst list into a new function.

This does not change functionality; just splits one block that
is deeply nested and indented out of a huge loop into a separate
function.

Otherwise
git push 'remote-name' 'refs/heads/*:refs/remotes/other/*'
will consider references in "refs/heads" of the remote repository
"remote-name", instead of the ones in "refs/remotes/other", which
the given refspec clearly means.

This means that send-pack and http-push will support pattern refspecs,
so builtin-push.c doesn't have to expand them, and also git push can
just turn --tags into "refs/tags/*", further simplifying
builtin-push.c
check_ref_format() gets a third "conditionally okay" result for
something that's valid as a pattern but not as a particular ref.

These follow the pattern of the push side configuration, but aren't
taken from anywhere else, because git-fetch is still in shell.

The new parser is different from the one in builtin-push in two ways:
the default is to use the current branch's remote, if there is one,
before "origin"; and config is used in preference to remotes.
