a temporary file should be used for UPDATE/DELETE of file tables.
Also use the "sorted" argument of index_init to help decide if
sorting of positions must be done.

be found in the column list and reallocated without their Value
causing a crash of some queries.

- Add a new CONNECT global variable connect_exact_info. Set to ON, it
tells CONNECT to return exact record numbers on info queries. If OFF
it just gives an estimate. In version 10.0.13 this was unconditionally
ON and caused info queries on remote tables to be extremely long and
was the subject of MDEV-6612.

1) Support of partitioning by connect. A table can be partitioned
by files, this is an enhanced MULTIPLE table. It can be also
partitioned by sub-tables like TBL and this enables table sharding.
2) Handling a CONNECT bug that causes in some cases extraneous rows
to remain in the table after an UPDATE or DELETE when the command
uses indexing (for not fixed file tables). Until a real fix is
done, CONNECT tries to ignore indexing and if it cannot do it
abort the command with an error message.

in this version. Sure enough, it never caused any improvement in
the execution speed and rather caused a small increase of execution
time. This is probably because values are sorted by rowid in each
range of CONNECT indexes. This could be reconsidered if a customer
have a need for processing very big files.

IS NULL operators was not recognized.

included by the program using them.
Continuing implementing the "catalog" tables (ex "info").
Already existing were the ODBC data source table and the
WMI column info table.
A common way to handle them will permit to develop many
other such tables. Implemented:
The ODBC column catalog table.
The ODBC tables catalog table.
The ODBC drivers catalog table.
The INFO table option is replaced by the CATFUNC string option
whode first letter specifies the information to retrieve:
C: Columns (of a table)
T: Tables (of a database)
S: Data sources
D: Drivers
