MXS-2732 Rename sqlite-src-3110100 to sqlite-src-3110100.old

Browse Source 
Originally, the sqlite installation was imported into the MaxScale
repository in the one gigantic MaxScale 1.4 -> 2.0 commit.

Consequently, there is no import commit to compare to if you want
to extract all MaxScale specific changes. To make it simpler in the
future, sqlite will now be imported in a commit of its own.

** Tclcmd: fts3_configure_incr_load ?CHUNKSIZE THRESHOLD?
**
** Normally, FTS uses hard-coded values to determine the minimum doclist
** size eligible for incremental loading, and the size of the chunks loaded
** when a doclist is incrementally loaded. This command allows the built-in
** values to be overridden for testing purposes.
**
** If present, the first argument is the chunksize in bytes to load doclists
** in. The second argument is the minimum doclist size in bytes to use
** incremental loading with.
**
** Whether or not the arguments are present, this command returns a list of
** two integers - the initial chunksize and threshold when the command is
** invoked. This can be used to restore the default behavior after running
** tests. For example:
**
** # Override incr-load settings for testing:
** set cfg [fts3_configure_incr_load $new_chunksize $new_threshold]
**
** .... run tests ....
**
** # Restore initial incr-load settings:
** eval fts3_configure_incr_load $cfg
