Now tree.h exports LIBXML2_NEW_BUFFER macro indicating that the
API uses the new buffers, important to keep code working with
both versions.
* tree.h buf.h: also export xmlBufContent(), xmlBufEnd(), and xmlBufUse()
to help port the old code
* buf.c: make sure the compatibility counters are updated on
buffer usage, to keep proper working of application compiled
against the old structures, but take care of int overflow
That condition is one raised when the parser should positively stop
processing further even to report errors. Best is to test is after
most GROW call especially within loops
This adds some internal limitationson XPath expression complexity,
and limits at runtime like depth of the stack and maximum size
for nodeset.
* xpath.c: implement the above as well as the maximum Name lenght
Those can be overrided by the XML_PARSE_HUGE option, they
are just default limits for Name lenght, dictionary size limits
and maximum amount of parser lookup.
* include/libxml/parserInternals.h: define the limits
* include/libxml/xmlerror.h: add a new error
* parser.c parserInternals.c: implements the new limits
* include/libxml/dict.h dict.c: adding 2 new functions xmlDictGetUsage
and xmlDictSetLimit allowing to review the amount of memory allocated
for dictionary strings. Aslo cleanup of various signed int used as
size values in the code.
* uri.c: cleanup the code doing the allocations, set up a structured
error handler to report memory errors, and set up an abitrary
limit on URI saving size
* error.c include/libxml/xmlerror.h: add a new FROM_URI indication
for structured error reporting, also adding strings for schematron
and buffer which were missing
Unless the XML_PARSE_HUGE option is given to the parser,
the value is XML_MAX_TEXT_LENGTH, i.e. the same than for a
text node within content.
Also cleanup some unsigned int used for memory size.

Mimic the old xmlBuffer strcture in xmlBuf to avaoid catastrophic
failures in case of old code directly reading ctxt->input->buf->buffer
Check on all buffer entry points if an error previously occured on
the buffer, and fail the operation if this is the case, the buffer
becomes immutable and unreadable.
When calling xmlParserInputBufferPush, the buffer may be reallocated
and at the input level the pointers for base, cur and end need to
be reevaluated.
* buf.c buf.h: add two new functions, one to get the base from the
input of the buffer, and another one to reset the pointers based
on the cur and base inded
* HTMLparser.c parser.c: cleanup to use the new helper functions
as well as making sure size_t is used for the indexes computations
This was scattered in a number of modules, xmlParserInputPtr
have usually their base, cur and end pointer set from an
xmlBuf used as input.
* buf.c buf.h: add a new function implementing this setup
* parser.c HTMLparser.c catalog.c parserInternals.c xmlreader.c
use the new function instead of digging into the buffer in
all those modules
* save.h: new header providing new functions currently internal
and xmlBuf counterparts of old xmlBuffer based ones
* xmlsave.c: convert functions to use xmlBuf as much as possible
* include/libxml/tree.h: adds xmlBufGetNodeContent and xmlBufNodeDump
as xmlBuf based equivalents of xmlNodeGetContent and xmlNodeDump
* tree.c: implements one new routine and converts xmlNodeBufGetContent
to use the xmlBuf equivalent. It should behave better as a result
in case of data larger than 2GB.
The main changes are when the internal of the buffers structure
were adressed directly, we now use routines coming from buf.h
The routine xmlParserInputRead() which wasn't used anywhere is
deprecated too.
Since the whole set of structures was public, the only way
to switch to size_t clean buffer is to introduce an incompatible
API change. Modifying the xmlParserInputBuffer and xmlOutputBuffer
structures is the best place to make this change as those
structures are deep into the parser feeding data, and no public
API suggest to build those manually.
* encoding.c: adds xmlCharEncFirstLineInput, xmlCharEncInput and
xmlCharEncOutput
* enc.h: the functions are not made public but added to this new header
This also add converter functions between xmlBuf and xmlBuffer
* buf.c buf.h: the old xmlBuffer routines but modified for size_t
and using xmlBuf instead of xmlBuffer
* Makefile.am: add the 2 new files
* include/libxml/xmlerror.h: add an entry for the new module
* include/libxml/tree.h: expose the xmlBufPtr type but not the
structure which stay private
Unless explicietely asked for when validating or replacing entities
with their value. Problem pointed out by Tom Lane <tgl@redhat.com>
* parser.c: do not load external parsed entities unless needed
* test/errors/extparsedent.xml result/errors/extparsedent.xml*:
add a regression test to avoid change of the behaviour in the future

Reported by Matt Budd <matt.budd@gmail.com>, the added support
for VS 2010 broke older version 2005 and 2008 because it assumed
some of the defines where present in all versions, fix that
to check the version of VS
