Log Message:
Update p5-JSON-XS to 2.21.
While here, marked as DESTDIR ready.

2.21 Tue Jun  3 08:43:23 CEST 2008
	- (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
	- remove the experimental status of the incremental parser interface.
	- move =encoding around again, to avoid bugs with search.cpan.org.
          when can we finally have utf-8 in pod???
        - add ->incr_reset method.

2.2  Wed Apr 16 20:37:25 CEST 2008
	- lifted the log2 rounding restriction of max_depth and max_size.
	- make booleans mutable by creating a copy instead of handing out
          the same scalar (reported by pasha sadri).
   	- added support for incremental json parsing (still EXPERIMENTAL).
	- implemented and added a json_xs command line utility that can convert
          from/to a number of serialisation formats - tell me if you need more.
        - implement allow_unknown/get_allow_unknown methods.
        - fixed documentation of max_depth w.r.t. higher and equal.
	- moved down =encoding directive a bit, too much breaks if it's the first
          pod directive :/.
        - removed documentation section on other modules, it became somewhat
          outdated and is nowadays mostly of historical interest.

2.1  Wed Mar 19 23:23:18 CET 2008
        - update documentation here and there: add a large section
          about utf8/latin1/ascii flags, add a security consideration
          and extend and clarify the JSON and YAML section.
        - medium speed enhancements when encoding/decoding non-ascii chars.
        - minor speedup in number encoding case.
	- extend and clarify the section on incompatibilities
          between YAML and JSON.
        - switch to static inline from just inline when using gcc.
        - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
        - fix some issues with UV to JSON conversion of unknown impact.
        - published the yahoo locals search result used in benchmarks as the
          original url changes so comparison is impossible.
