5a29217dda git-remote-mediawiki: more efficient 'pull' in the best case
The only way to fetch new revisions from a wiki before this patch was to
query each page for new revisions. This is good when tracking a small set
of pages on a large wiki, but very inefficient when tracking many pages
on a wiki with little activity.

Implement a new strategy that queries the wiki for its last global
revision, queries each new revision, and filter out pages that are not
tracked.

4465b6d610 git-remote-mediawiki: refactor loop over revision ids
Without changing the behavior, we turn the foreach loop on an array of
revisions into a loop on an array of integer. It will be easier to
implement other strategies as they will only need to produce an array of
integer instead of a more complex data-structure.

b1ede9a9f2 git-remote-mediawiki: change return type of get_mw_pages
The previous version was returning the list of pages to be fetched, but
we are going to need an efficient membership test (i.e. is the page
$title tracked), hence exposing a hash will be more convenient.

6a9e55b0fc git-remote-mediawiki: import "File:" attachments
Add the symmetrical feature to the "File:" export support in the previous
patch. Download files from the wiki as needed, and feed them into the
fast-import stream. Import both the file itself, and the corresponding
description page.

b3d9859598 git-remote-mediawiki: send "File:" attachments to a remote wiki
The current version of the git-remote-mediawiki supports only import and
export of plain wiki pages. This patch adds the functionality to export
file attachments (i.e. the content of the File: MediaWiki namespace),
which are also exposed by MediaWiki API.

This requires a recent version of MediaWiki::API (Version 0.37 works.
Version 0.34 doesn't).

721a533f8c git-remote-mediawiki: don't "use encoding 'utf8';"
The use of this statement is generally discouraged, and is too intrusive
for us: it forces the HTTP requests made by the API to contain only valid
UTF-8 characters. This would break the upload of binary files.

While we're there, simplify the code a bit: since log --format=%s anyway
shows the subject line as a single line, no need to split to take the
first line.

a7271ad1dc git-remote-mediawiki: add credential support
The previous version implemented the possibility to log in a wiki, but
the username and password had to be provided as configuration variables.
We add the possibility to use the Git credential system to prompt
the password.

The support if implemented with generic functions that mimic the C API,
designed to be usable from other contexts in the future (i.e. they may
migrate to Git.pm if someone is interested).

While we're there, do a bit of refactoring in mw_connect_maybe.

9fb79503e6 git-remote-mediawiki: don't include HTTP login/password in author
On the MediaWiki side, the author information is just the MediaWiki login
of the contributor. The import turns it into login@$wiki_name to create
the author's email address on the wiki side. But we don't want this to
include the HTTP password if it's present in the URL ...

93f0d33818 git-remote-mediawiki: allow push to set MediaWiki metadata
Push can not set the commit note "mediawiki_revision:" and update the
remote reference. This avoids having to "git pull --rebase" after each
push, and is probably more natural. Make it the default, but let it be
configurable with mediawiki.dumbPush or remote.<remotename>.dumbPush.

428c995c4e Add a remote helper to interact with mediawiki (fetch & push)
Implement a gate between git and mediawiki, allowing git users to push
and pull objects from mediawiki just as one would do with a classic git
repository thanks to remote-helpers.

The following packages need to be installed (available on common
repositories):

  libmediawiki-api-perl
  libdatetime-format-iso8601-perl

Use remote helpers in order to be as transparent as possible to the git
user.

Download Mediawiki revisions through the Mediawiki API and then
fast-import into git.

Mediawiki revision number and git commits are linked thanks to notes
bound to commits.

The import part is done on a refs/mediawiki/<remote> branch before
coming to refs/remote/origin/master (Huge thanks to Jonathan Nieder
for his help)

We use UTF-8 everywhere: use encoding 'utf8'; does most of the job, but
we also read the output of Git commands in UTF-8 with the small helper
run_git, and write to the console (STDERR) in UTF-8. This allows a
seamless use of non-ascii characters in page titles, but hasn't been
tested on non-UTF-8 systems. In particular, UTF-8 encoding for filenames
could raise problems if different file systems handle UTF-8 filenames
differently. A uri_escape of mediawiki filenames could be imaginable, and
is still to be discussed further.

Partial cloning is supported using one of:

git clone -c remote.origin.pages='A_Page  Another_Page' mediawiki::http://wikiurl

git clone -c remote.origin.categories='Some_Category' mediawiki::http://wikiurl

git clone -c remote.origin.shallow='True' mediawiki::http://wikiurl

Thanks to notes metadata, it is possible to compare remote and local last
mediawiki revision to warn non-fast forward pushes and "everything
up-to-date" case.

When allowed, push looks for each commit between remotes/origin/master
and HEAD, catches every blob related to these commit and push them in
chronological order. To do so, it uses git rev-list --children HEAD and
travels the tree from remotes/origin/master to HEAD through children. In
other words:

* Shortest path from remotes/origin/master to HEAD
* For each commit encountered, push blobs related to this commit
