Improved parsing support for OOXML spreadsheets (.xlsx)

As reported edycop in mantis 765 (
http://mantis.tokeek.de/view.php?id=765 ), parsing of xlsx files was
quite incomplete.
Now properly support "Shared String Table" entry in Office Open XML
spreadsheets, an also detect embedded URLs.

Integrating the Apache poi-ooxml library could be an option for finer
OOXML formats support, but their SAX style parsing example (
http://poi.apache.org/spreadsheet/how-to.html#xssf_sax_api ) tends to
show that a custom SAX handler is still efficient for lightweight and
low memory footprint processing.

Started support of partial parsing on large streamed resources.

Thus enable getpageinfo_p API to return something in a reasonable amount
of time on resources over MegaBytes size range.
Support added first with the generic XML parser, for other formats
regular crawler limits apply as usual.

Added a generic XML parser, able to parse elements text and URLs.

This parser adds support for any XML based format other than already
supported XML vocabularies such XHTML, RSS/Atom feeds... It will
eventually be used as a fallback if one of these specific parsers fail,
before falling back to the existing genericParser which extracts not
that much useful information except URL tokens.
