speed improvements: change scheduler to SCHED_FIFO, Disable realtime throttling, use in-memory db for sqlite core channels table (set core-db-name to 'core' in switch.conf.xml for previous behaviour of using the core sqlite file, now only aliases will be in the persistant db)

If you pass --enable-skip-subdirectories then configure will skip
configuring or reconfiguring libraries and simply configure the FS
core itself.

The default remains the same: we show the huge ClueCon nag banner on
startup and in fs_cli.

However, if you pass --disable-huge-cluecon-nag, no banner will be
shown.

If you pass --enable-modest-cluecon-nag, a modest text-based ClueCon
reminder will be shown instead.
