3835bf8449 A handful of fixes related to error detection 
- Fix assertion failure by breaking the switch if an error token is next
   when previous was a processing instruction.
 - Fix <!notation parsing by skipping ident chars instead of spaces.
 - Improve checking of processing instruction 'target'-end and what error
   string is generated.
 - For now put all of the processing instruction data in the error token.
 - Remove a DBG()-print.

c993a0012e Add basic support for detection errors while scanning 
It mostly uses the checking for incompleteness already in place. Tested
lightly so it will definately need some more work.

f75ccffbc7 Fix SGML parsing and scanning so that all tests succeeds 
This includes checking the return token of get_next_dom_scanner_token() and
fixing the calculated size of recovered processing instruction data tokens.

It is mostly just ignored for now. The SGML parser test tool will however
return parser code.

021af4e87c Although aware ELinks doesn't need another sgml/doctype here is DocBook 
It was created a long time ago so (I think) it deserves to survive. It
maps .sgml files to applicatino/docbook+xml and uses the highlighter.

a578ed4667 Make the SGML scanner (optionally) keep track of line numbers 
A new line is either \n or \f. The main logic for counting lines is in
skip_sgml{,_chars,_space}. For the general case where line numbers are not
wanted the code tries to avoid the extra checks for newlines.

This will be useful for reporting errors when loading the XBEL file.

57168e1fbc Handle <element path=/to/%61-&\one";files/> as a self-closing tag 
Before the '/' before '>' would be interpreted as part of the attribute
value.  Hope this is sensible slurping of the markup soup.

1a177491a0 Fix SGML parsing of processing instructions (<?xml ...?>) 
It involves adding a new scanner state which is used only to generate a new
processing instruction (PI) data token. This removes some scanner specific
code from the parser and makes handling of PIs more generic. The data of
XML PIs are still parsed as attributes and added to the PI node.

The 6th test now succeeds. Hurrah!
