CONC-724: Added TLS verification callback support

Browse Source 
For testing purposes (the python3 dummy server can't handle
further communication after TLS handshake succeeded) support
for verification callback was added.

my_bool callback(MYSQL *mysql, unsigned int *flags, my_bool verified)

Parameter:
  - mysql     connection handle for current connection
  - flags     verification flags
  - verified  true if callback was called after verification,
              otherwise false

Return value:
  - False (0) to continue
  - True  (1) to abort tls connection

The callback function can be registered via
mysql_optionsv(mysql, MARIADB_OPT_TLS_VERIFICATION_CALLBACK, callback);
