This mega-patch rips out the FixNesting implementation and the related
ChildDef components. The primary algorithmic change is to convert from
use of tokens to tree nodes, which are far more amenable to the style
of processing that FixNesting uses. Additionally, FixNesting has been
changed to go bottom-up rather than top-down, in order to avoid needing
to implement backtracking.
This patch simplifies a good deal of the relevant logic, since we no
longer need to continually recalculate the nesting structure when
processing things. However, the conversion to the alternate format
incurs some overhead, so for small inputs these changes are not a win.
One possibility to greatly reduce the constant factors here is to switch
to entirely using libxml's representation, and never serializing tokens;
this would require one to rewrite injectors, however.
The iterative post-order traversal in FixNesting is a bit subtle, but
we have essentially reified the stack and continuations.
We've removed support for %Core.EscapeInvalidChildren.

This fix is slightly hackish, as we simply treat comments as whitespace.
This should largely be correct, and breaks no current test cases,
although it could result in noncompliant behavior.

This commit is a limited implementation of the "active formatting
elements" algorithm implemented in HTML5, which preserves certain
formatting elements such as <a> and <b> when exiting or entering nodes.

* Added Charsets and Character attribute types
* Fix a heavily recursive form of ContentSets, this allows a content-set
to include another content-set which includes another content-set, and
so forth.

The newest autoclose code uses the elements property in whether or not an
element should be closed by a particular tag. The heuristic is simple; if
the element doesn't allow that tag as a child, it closes the parent
container. This doesn't work, however, with <blockquote>, which while not
allowing inline styles under Strict doctypes, requires them to be passed
through MakeWellFormed.
The fix was to transition MakeWellFormed to call a method to retrieve the
elements, and then have StrictBlockquote implement a special version of
this method. Future versions of HTML Purifier may be more flexible in this
regard--further study of the HTML5 specification is required.

- Convert a number of calls to use new constructor signature for Generator
- Make generator require configuration; this exposes a number of latent bugs
- Removed generator hack
- Convert Printers to use new optimized ConfigSchema format
- Hack with Printer configuration; pass an array(generator config, render config) to distinguish between output and target.
- HTML/CSS Printers need to be primed, otherwise fatal errors
- Convert a few test-cases to use member properties

- HTMLPurifier.autoload.php added to register autoload handler
- Removed redundant chdir in maintenance script
- Modified standalone to use HTMLPurifier.includes.php for including stuff
- Added maintenance script remove-require-once.php which we used once and should never use again

- Update TODO list
- URISchemeRegistry doesn't return a reference for instance anymore, should do the same for other singletons

- Buggy treatment of end tags of elements that have required attributes fixed (does not manifest on default tag-set)
- Spurious internal content reorganization error suppressed
. Error unit tests can now specify the expectation of no errors. Future iterations of the harness will be extremely strict about what errors are allowed

- Fixed buggy chameleon-support for ins and del
. Removed context variable ParentType, replaced with IsInline, which
is false when you're not inline and an integer of the parent that
caused you to become inline when you are (so possibly zero)
. Removed ElementDef->type in favor of ElementDef->descendants_are_inline
and HTMLDefinition->content_sets
. StrictBlockquote now reports what elements its supposed to allow,
rather than what it does allow
. Removed HTMLDefinition->info_flow_elements in favor of
HTMLDefinition->content_sets['Flow']
. Removed redundant "exclusionary" definitions from DTD roster
. StrictBlockquote now requires a construction parameter as if it
were an Required ChildDef, this is the "real" set of allowed elements

- Added @public identifiers to properties that the Printers are using.
- Augmented Printer::getClass() to include meta-info about the object (contained inside parentheses). Currently supports: enum, composite and multiple.
- Remove all linebreaks from Printer output
- Document Printer_HTMLDefinition's methods.

+ Transparently handles inline elements in block context (blockquote)
! Added GET method to demo for easier validation, added 50kb max input size
! New directive %HTML.BlockWrapper, for block-ifying inline elements
! New directive %HTML.Parent, allows you to only allow inline content
- Added missing type to ChildDef_Chameleon
. ChildDef_Required guards against empty tags
. Lookup table HTMLDefinition->info_flow_elements added
. Added peace-of-mind variable initialization to Strategy_FixNesting
