Tested that parser cache keys stay the same, before and after this
change.
Also use the more obvious ObjectCache::getLocalClusterInstance() instead
of looking up the main cache type in config and using
ObjectCache::getInstance().

This revises 2877402276, which was
reverted in master due to unexpected issues with `-{{...}} ` markup
on translatewiki and enwiki. Test cases are added to ensure that this
is parsed as a template, not as language converter markup.
https://www.mediawiki.org/wiki/Preprocessor_ABNF is the canonical
documentation for the preprocessor; this will be updated after this
patch is merged. The basic principles described in that page are
maintained in this patch:
* Rightmost opening structure has precedence: `-{{` is parsed as a
dash followed by template opening.
* `{{{` has precedence over `{{` and `-{`: `-{{{{` is parsed as
`-{` `{{{` since we first grab the rightmost `{{{`.
A bunch of test cases were added to verify the "ideal precedence"
order described on that wiki page.
This patch introduced some minor incompatibilities in existing
markup, in particular with chemical formulae in templates.
Fixes for these are being tracked at

This ensures that `{{echo|-{R|foo}-}}` is parsed correctly as
a template invocation with a single argument, not as two separate
arguments split by the `|`.

This is about template parameters. They can be indexed by position (int) or
name (string). The returned value is always a string, or false (bool) on
failure.

Instead of declaring the array of rules within both Preprocessor_DOM:: and
Preprocessor_Hash::preprocessToXml(), declare it as a protected property of the
parent Preprocessor class.

Follows-up 1559be9f7a, which caused "Preprocessor" to be used as the
cache prefix for all subclasses, by using late static binding to access
the constant. Though use of that feature has been discouraged[1], this
change is a straightforward bug fix, and any improvements can be made
separately.

* Consolidate nearly-identical caching code in Preprocessor_DOM and
Preprocessor_Hash by making Preprocessor an abstract class rather than an
interface and by implementing Preprocessor::cacheSetTree() and
Preprocessor::cacheGetTree().
* Cache trees for wikitext blobs that have length equal or greater to
PreprocessorCacheThreshold. Previously they needed to be greater than
PreprocessorCacheThreshold, so this changes the requirement by one character.
I did it because it seems more natural.
* Modernize the code to use singleton service objects rather than globals.
We spend a lot of time in the Preprocessor, so it would be nice for this code
to be well-factored and clear.

Add PPFrame::NO_TAGS, set by PPFrame::RECOVER_ORIG, to preserve extension
tags rather than expanding them.

Add functions to frames to control the TTL of their output, and expose
this via expandtemplates in the API.

Most wikitext is safe to parse once and then cache for when that same
wikitext is used again, such as for multiple transclusions of the same
template within a page. There are occasions, though, where some piece of
wikitext has side effects and so should not be cached; a prominent
example of such wikitext is the <ref> and <references> tags in Cite.php.
This change adds PPFrame::setVolatile so parser hooks such as <ref> and
<references> can indicate that they have done something that should not
be cached, and PPFrame::isVolatile so that callers of PPFrame::expand
can know when to avoid caching.

Remove the parser's global $mTplExpandCache, and replace it with an
alternative that is separated by parent frame. This allows the integrity
of the empty-frame expansion cache to be maintained while also allowing
parent frame access.
A page with 3 copies of
http://ja.wikipedia.org/wiki/%E4%B8%AD%E5%A4%AE%E7%B7%9A_(%E9%9F%93%E5%9B%BD)
has the following statistics: Without this change, there are 4625 cache hits
on this page, and a sample of 3 parses took 16.6, 16.9, and 16.8 seconds.
With this change, there are 2588 cache hits, and a sample of 3 parses took
16.7, 16.7, and 17.0 seconds.

Remaining are the classes containing underscores and possibly a few other
issues that will be addressed soonish.

Swapped some "$var type" to "type $var" or added missing types
before the $var. Changed some other types to match the more common
spelling. Makes beginning of some text in captial.
Also added some missing @param.

When inserting XML elements inline <such as this one>, doxygen chokes
about it not being known. Simply enclosing the tag in double quotes
prevents doxygen from emitting a warning.
Also enclosed a few invalid functions calls such as \. and double quoted
the HTML entities such as &foobar;

Add $indexOffset parameter to PPFrame::newChild(). This makes it
possible to use newChild() for interpreting named parameters to
invoke in Scribunto -- otherwise I would have had to duplicate its
functionality, which would have been tricky given that I wanted to
make a real frame with an expand() method. Setting $indexOffset allows
newChild() to start counting numbered parameters from somewhere other
than the first pipe character, leaving room for the Scribunto function
name.
Fixed PPCustomFrame_*::getArguments(), was missing for no apparent
reason. I didn't end up using it in Scribunto, but there's no harm in
adding it anyway.

* Wrote a tool to check the integrity of the autoloader class list, fixed some issues that came up.
* Start the autoloader before LocalSettings.php, so that when an extension writer thinks an inefficient one-file special page extension is the way to go, they don't have to use explicit includes to make the class inheritance work. Should continue to work with $IP set in LocalSettings.php as long as $IP is set before extensions are included.
