Render metadata when needed

This changes fundamentally when metadata is rendered. This commit
introduces a new cache file for every page that just contains a
timestamp and is updated whenever the metadata of that page is rendered.

Metadata is rendered when p_get_metadata is called and the last
rendering has been before a page, metadata, configuration or renderer
update or purge is set like in the xhtml renderer cache.

Metadata is no longer automatically rendered when the xhtml renderer
cache isn't used but will still be rendered when needed as
p_get_metadata is called in the cache.

Metadata is also no longer rendered in the indexer script when missing
as that is already done by pageinfo() before anything else is done so
the indexer script won't be called when there is no metadata file.

This patch does two things: It makes sure the native json_decode() will
honor the JSON_LOOSETYPE option of the class and it also adds way
to skip the use of the native function completely. The latter is
necessary for slightly non-standard JSON data.

Indexer improvement: regex instead of arrays for lines

When updating a single line that line was split into an array and in a
loop over that array one entry was removed and afterwards a new one
added. Tests have shown that using a regex for doing that is much faster
which can be easily explained as that regex is very simple to match
while a loop over an array isn't that fast. As that update function is
called for every word in a page the impact of this change is
significant.

Indexer improvement: Only write the words index when needed

This adds a simple boolean variable that tracks if new words have been
added. When editing a page in many cases all words have already been
used somewhere else or just one or two words are new. Until this change
all words indexes read were always written, now only the changed ones
are written. The overhead of the new boolean variable should be low.

Indexer speed improvement: joined array vs. single lines

From my experience with a benchmark of the indexer it is faster to first
join the array of all index entries and then write them back together
instead of writing every single entry. This might increase memory usage,
but I couldn't see a significant increase and this function is also only
used for the small index files, not for the large pagewords index.
