* ODBC Connect cosmetic fixes
- Update command for connection for default `peer` authentication for user
`postgres` (unless changed in `pg_hba.conf`).
- Update command for privilege to be more verbose.
- Update path for `.sql` file
- Update instructions for `pg_hba.conf` file to use unix socket
(`local`) type as well as TCP/IP type `host`.
- Update instruction about usage of user dsn (data source file) over
system dsn.
- Update path of `odbc-postgresql` driver path in comment
* Connect SE: update ODBC result file

Continue with similar changes as done in 19af1890 to replace sprintf(buf, ...)
with snprintf(buf, sizeof(buf), ...), specifically in the "easy" cases where buf
is allocated with a size known at compile time.

There are currently two things causing ASAN hits on CONNECT engine when
the plugin is used as a dynamic module. These are libxml2 and libodbc.
libxml2 has some quirks when not the first and last thing called in the
main thread of an application, some of the global memory isn't cleaned
up correctly. The same is assumed of libodbc but this does not have
explicit API for this.
This is being fixed in two ways.
First we are removing the libxml2 cleanup call. This is because the
current one is messy and whatever it fixed has gone away. But also
because if this is called and libxml2 is used again this can cause
issues. For example if two different plugins to MariaDB both happen to
use libxml2.
The second fix is a hack that exploits `STB_GNU_UNIQUE` so that when
compiled with ASAN the plugin will remain in memory after dlclose().
This allows libodbc to cleanup and has the added advatage that we will
get clean stacks from ASAN for CONNECT when the leak is detected at the
end of execution.
Details of the `STB_GNU_UNIQUE` method can be found here:

| | | |
| | | |
| | | |
| | | | |
When an UPDATE or DELETE was executed with a WHERE condition it would
crash the MariaDB server. This is because the code expects the WHERE
condition to have generated a query string but it hasn't.
Also updates the ODBC test results for current MariaDB version.

* MDEV-29426 Fix memory leak in CONNECT JSON/BSON
If information is being gathered on JSON/BSON tables we leak the heap
allocated to the table class. With this fix we close and cleanup
instead, just as we do for XML tables.

These files are currently not being used nor compiled in MariaDB. The
use of large lists of 'case' statements in these source files are also
not a great way to represent translated strings. This git history can
be referred to when a better translation interface can be implemented
in the future.
Therefore, these files can be removed to cleanup the MariaDB codebase.

Modern software (including text editors, static analysis software,
and web-based code review interfaces) often requires source code files
to be interpretable via a consistent character encoding, with UTF-8 or
ASCII (a strict subset of UTF-8) as the default. Several of the MariaDB
source files contain bytes that are not valid in either the UTF-8 or
ASCII encodings, but instead represent strings encoded in the
ISO-8859-1/Latin-1 or ISO-8859-2/Latin-2 encodings.
These inconsistent encodings may prevent software from correctly
presenting or processing such files. Converting all source files to
valid UTF8 characters will ensure correct handling.
Comments written in Czech were replaced with lightly-corrected
translations from Google Translate. Additionally, comments describing
the proper handling of special characters were changed so that the
comments are now purely UTF8.

Thats because Nx and Sx column members are not reset when changing file.

In addition to files and Mongo collections, JSON as well as XML and CSV data can be retrieved
from the net as answers from REST queries. Because it uses and external package (cpprestsdk)
this is currently available only to MariaDB servers compiled from source.

-- Also include some changes specific to MariaDB 10.3.

is compatible in the start_stmt function. It nows do the
