Fix indexing numeric words in page contents

Since a8dba4523d2ecd09dd69a68a36673eaf5c009c57 the search index didn't
properly index numeric words anymore, instead they were added as new
words to the word list each time they were indexed, leading to an
ever-increasing index size.

Indexer: Remove broken and dead readdircache code FS#2771

The code that is removed in this commit has either never been used
(listIndexLenghts) or was completely broken (cacheIndexDir) and was
introduced in the indexer rewrite in 2010. The idea of the rewrite was
to update the readdir cache after every index change instead of on demand.
What the code actually did was removing every updated index from the
cache as it used a wrong if condition. Simply fixing the condition
wouldn't fix the problem as then only updated indexes would be added to
the cache and furthermore the rewrite simply ignored the readdircache
setting. For now the safest solution seems to be removing the code. It
could be added again in a changed form in a future version.

Indexer: Make $Indexer in idx_get_indexer() global instead of static

This avoids problems with test cases that use the indexer and the PID
cache - the index is cleaned between test cases but the PID cache
wasn't cleaned. Now PHPUnit can unset the global $Indexer between test
cases.
