With spell checkers available in all modern browsers, having a spell checker in
DokuWiki's core code is no longer necessary. This patch removes the spell
checking feature. It will be made available as optional plugin.

This patch enables the use of the X-Sendfile extension offered by certain
webservers to deliver static files after running a dynamic script. This
combines the flexibility of a PHP file to check for authorization, caching
and resizing with the low memory footprint and high performance of static
file delivery of the webserver.

Because correct smart quote parsing with regular expressions is nearly
impossible, especially when dealing with quote usage in languages different
from english, the typography configuration option was changed.

0 means to completely disable any typography replacements
1 will only handle the multiply entitity and double quotes, this should
  nearly always work without problems and is the new default
2 will add singlequote parsing. This might break because single quotes and
  apostrophes are not always easily distinguishable. Especially in languages
  where single quote openings and apostrophes are different characters you
  might experience problems. For english it should nearly always work.

This fix adds a new configuration setting, 'auth_security_timeout', which controls the duration (seconds) before authentication
information is rechecked.  The default value is set to 900 seconds (15 minutes). Wiki installations particularly concerned
about security should set this value to 0.

DokuWiki maintains a copy of the most recent authentication details in both a browser cookie and server session.  Normally these
values are compared on each page visit.  If the comparison passes the user is accepted. The same data will be used over and
over until either the cookie or the session expires.  FS#1085 is concerned with updates to the original authentication data not
being able to affect this comparison.  The new 'auth_security_timeout' setting will force expiration of the saved data after the
specified period has elapsed.

Re-authentication may affect page response, especially on systems which use remote authentication systems.

This fix is considered partial and should be reviewed after the next release with a view to extending the authentication class
to allow those mechanisms which are able to control when DW should revoke authentication.

Following the problem with IE's mimetype handling described at
http://www.splitbrain.org/blog/2007-02/12-internet_explorer_facilitates_cross_site_scripting
this patch adds a new option (on by default) to check the first 256
bytes of uploaded files against a list of a few HTML tags and denies
the upload of such a file. In rare occasions this may block harmless
and valid files, but that's price we have to pay for Microsoft's
stupidity.

Users who need HTML uploads should disable this check. (Don't do that on
open Wikis!)

On certain platforms the ignore_user_abort function does not work as expected, resulting
in a non working indexer webbug. Users with such a broken system (IIS+PHP as CGI) can
enable this option to work around the problem (resulting in longer load times for the
webbug).

This patch changes fetch.php ability to download external files. It now checks
for the returned MIME type and will only download images. For all other
MIME types a redirect is sent back to the browser. This reduces the risc of
being misused as open proxy.

Additionally the download facility is disabled completly by default by setting
the fetchsize option to 0. Users who want the feature need to overwrite the option
in their local.php.

Background: The ability to download external files is needed to resize external
images on the server side. When disabled, a redirect is sent to the browser which
will download the fullsize image and rescale it on the client side which is more
bandwidth and CPU intensive.

This patch adds a feature to let DokuWiki automatically check if updates are
available or any other important messages (like security warnings) and then
display this info to the admin user.

DokuWiki will contact the URL http://www.splitbrain.org/lib/exe/msg.php
with a parameter telling it which messages it already know (read from
conf/msg) - the server side script then will return all new messages.

The messages will be displayed until DokuWiki was upgraded or conf/msg
was updated manually. Messages are cached and only checked once a day.

The messenger URL will probably change before the next release.

This patch provides a rewritten changelog system that is designed to run
efficiently on both small and large wikis. The patch includes a plugin to
convert changelogs from the current format. The conversion is
non-destructive and happens automatically. For more information on the new
changelog format see "http://wiki.splitbrain.org/wiki:changelog".

Structure
In short the changelog is now stored in per-page changelog files, with a
recent changes cache. The recent changes cache is kept in
"/data/meta/_dokuwiki.changes" and trimmed daily. The per-page changelogs
are kept in "/data/meta/<ns>/<page_id>.changes" files. To preserve
revision information for revisions stored in the attic, the "*.changes"
files are not removed when their page is deleted. This allows the full
life-cycle of page creation, deletion, and reversion to be tracked.

Format
The changelog line format now uses a general "line type" field in place of
the special "minor" change syntax. There is also an extra field that can
be used to store arbitrary data associated with special line types. The
reverted line type (R) is a good example. There the extra field holds the
revision date used as the source for reverting the page. See the wiki for
the complete syntax description.

Code Notes
The changelog functions have been rewritten to load the whole file only if
it is small. For larger files, the function loads only the relevant
chunk(s). Parsed changelog lines are cached in memory to speed future
function calls.

getRevisionInfo
A binary search is used to locate the chunk expected to contain the
requested revision. The whole chunk is parsed, and adjacent lines are
optimistically cached to speed consecutive calls.

getRevisions
Reads the changelog file backwards (newest first) in chunks until the
requested number of lines have been read. Parsed changelog lines are
cached for subsequent calls to getRevisionInfo. Because revisions are read
from the changelog they are no longer guaranteed to exist in the attic.

(Note: Even with lines of arbitrary length getRevisionInfo and
getRevisions never split changelog lines while reading. This is done by
sliding the "file pointer" forward to the end of a line after each blind
seek.)

isMinor
Removed. To detect a minor edit check the type as follows:
$parsed_logline['type']
