72e29f9a3d html: Fix quadratic behavior in push parser 
Fix quadratic behavior related to unquoted attribute values. We really
have to replicate parts of the HTML5 state machine to find the end of
tags relibably.

Fixes #533.

4f329dc524 parser: Implement xmlCtxtParseContent 
This implements xmlCtxtParseContent, a better alternative to
xmlParseInNodeContext or xmlParseBalancedChunkMemory. It accepts a
parser context and a parser input, making it a lot more versatile.

xmlParseInNodeContext is now implemented in terms of
xmlCtxtParseContent. This makes sure that xmlParseInNodeContext never
modifies the target document, improving thread safety.
xmlParseInNodeContext is also more lenient now with regard to undeclared
entities.

Fixes #727.

2e63656ec6 parser: Check return value of inputPush 
inputPush typically doesn't fail because we pre-allocate the input
table. The return value should be checked nevertheless.

7e0bbbc143 parser: New input API 
Provide a new set of functions to create xmlParserInputs. These can be
used for the document entity or from external entity loaders.

- Don't require xmlParserInputBuffer.
- All functions take a base URI.
- All functions take an encoding as string.
- xmlNewInputURL also takes a public ID.
- xmlNewInputMemory takes a size_t.
- Optimization hints for memory buffers.

Improve documentation.

Only call xmlInitParser before allocating a new parser context.

Call xmlCtxtUseOptions as early as possible.

d944a41515 parser: Fix in-parameter-entity and in-external-dtd checks 
Use in ctxt->input->entity instead of ctxt->inputNr to determine whether
we are inside a parameter entity.

Stop using ctxt->external to check whether we're in an external DTD.
This is signaled by ctxt->inSubset == 2.

8cd563174a html: Don't close fd in htmlCtxtReadFd

54c70ed57f parser: Improve error handling 
Introduce xmlCtxtSetErrorHandler allowing to set a structured error for
a parser context. There already was the "serror" SAX handler but this
always receives the parser context as argument.

Start to use xmlRaiseMemoryError.

Remove useless arguments from memory error functions. Rename
xmlErrMemory to xmlCtxtErrMemory.

Remove a few calls to xmlGenericError.

Remove support for runtime entity debugging.

c2bbeed1fd io: Fix memory lifetime issue with input buffers 
xmlParserInputBufferCreateMem must make a copy of the buffer.

This fixes a regression from 2.11 which could cause reads from freed
memory depending on the use case.

Undeprecate xmlParserInputBufferCreateStatic which can avoid copying
the whole buffer.

c011e7605d globals: Remove unused globals from thread storage 
Setting these deprecated globals hasn't had an effect for a long time.
Make them constants. This reduces the size of per-thread storage from
~700 to ~250 bytes.
