Nick Wellnhofer db8b9722cb parser: Deprecate global parser options
Note that setting global options has no effect anyway when using any of
the modern parser API functions which take an option argument like
xmlReadMemory or when using xmlCtxtUseOptions.

Global options only have an effect when using old API functions
xmlParse* or xmlSAXParse* or when using an xmlParserCtxt without calling
xmlCtxtUseOptions.

Unfortunately, many downstream projects still modify global parser
options often without realizing that it has no effect. If necessary,
switch to the modern API. Then you can safely remove all code that
changes global options.

Here's a list of deprecated functions and global variables together with
the corresponding parser options.

- xmlSubstituteEntitiesDefault, xmlSubstituteEntitiesDefaultValue
  Parser option XML_PARSE_NOENT

- xmlKeepBlanksDefault, xmlKeepBlanksDefaultValue
  Inverse of parser option XML_PARSE_NOBLANKS

- xmlPedanticParserDefault, xmlPedanticParserDefaultValue
  Parser option XML_PARSE_PEDANTIC

- xmlLineNumbersDefault, xmlLineNumbersDefaultValue
  Always enabled by new API

- xmlDoValidityCheckingDefaultValue
  Parser option XML_PARSE_DTDVALID

- xmlGetWarningsDefaultValue
  Inverse of parser option XML_PARSE_NOWARNING

- xmlLoadExtDtdDefaultValue
  Parser options XML_PARSE_DTDLOAD and XML_PARSE_DTDATTR
