Removed "<select expression> INTO <destination>" deprication.

Browse Source 
This was done after discussions with Igor, Sanja and Bar.

The main reason for removing the deprication was to ensure that MariaDB
is always backward compatible whenever possible.

Other things:
- Added statistics counters, mainly for the feedback plugin.
  - INTO OUTFILE
  - INTO variable
  - If INTO is using the old syntax (end of query)
