Roxie generated filenames for index parts were incorrect

Roxie generating file names for index parts other than the top-level
key incorrectly. This would lead to some confusion, and possibly additional
copying of files, but no other ill effect as far as I can see.

Roxie file cache was not checking timestamps

The code for checking and comparing filestamps when deciding if Roxie's
cached copy of a file was up to date seems to have been lost in the
big refactoring of package files, meaning that file mismatches would only
be detected when the size changed.

This had a few unfortunate effects:

1. Index changes are likely to be only detected by slaves but not by server
   nodes. This leads to 'partially suspended' queries which were are not
   giving helpful error messages.
2. If data is refreshed on thor, Roxie might continue to read a previously
   cached version of the data, even if Roxie was restarted.

See gh-2096. This is not a complete fix for all the issues there, since Roxie
is still falsely reporting that two versions of a data file are required
at the same time when all queries using the previous version have been
unloaded.

Roxie assert error on partially suspended queries

If a Roxie slave thinks that a query is suspended, but the server does not
(this can happen when a file part is missing, for example), then the error
reported if the query is executed wille be an internal assert failure
rather than something more helpful.

See issue gh-2096.

Roxie caching local files too long

Roxie was nto clearing the local file cache when the last query
that referenced a file was released. This means that it was not
possible to load a new query that referenced an updated version
of a file without restarting roxie

Fixes gh-2096.
