rpc.php overhaul
* Mark things static in the class rather than use a constructor every single invocation of the service. * Don't call mysql_real_escape_string() before we even have a database connection, and don't do work in the database if we don't need to. * Formatting consistency fixups in a few places. * Add new process_query() helper function; use this instead of copy-pasted code in all of the RPC method calls. * Remove the escaping code meant to fix FS#15526, introduced in commit 4d1eb4dd7ac631. It broke more than it solved, only fixed the output in one of three RPC calls (and who knows what the web interface then also does), and proper encoding should be done at the database level rather than up here. Lukas: Add special case for "info" queries to process_query() (return a single result instead of an array of results here).
