6bf9557d00 CONC-709: Fix crash when sending NULL_LENGTH in field description 
Instead of checking the lengths given by two offsets, we have to
check if NULL_LENGTH was sent before (and return an error).

45feebb99d Remove server certification verification 
Since the server certification option is used by client
only, there is no need to have this flag in server and or
client capabilities. The server itself validates client
certificate depending on the user definition.

3ce51b0b3e Fix for CONC-587: 
Since alerts may happen after handshake (for example with described
test in CONC-587 using TLSv1.3 protocol or by renegotiation) the
tls error message needs to be retrieved if error is a protocol error
(SSL_ERROR_SSL) and/or if errno was not set.

f6b8fe10c3 Fix for CONC-568: 
If multiple threads attempt to connect to a server using a
dynamically loaded authentication plugin the error
"plugin is already loaded" might occur. This is caused
by a race condition if one thread waits for a lock to
load the plugin, while another process which obtained the lock
already loaded the plugin.

The API function mysql_load_plugin_v() now returns
the plugin handle (instead of raising an error and returning
a NULL handle) even if the plugin was already loaded.

d19c7c6926 Fix for CONC-543 (hash functions conflict with GnuTLS) 
To allow static linking with GnuTLS hash lookup functions are now
prefixed with ma_hashtbl_. The files hash.c and hash.h were renamed
to ma_hashtbl.c and ma_hashtbl.h

6a0c8ff2e5 Fix for CONC-457: 
mysql_list_processlists was marked as deprecated in MySQL 4.0 and not
updated anymore. It exists still in latest MySQL and MariaDB connectors.
It now supports the 4.1 protocol, using 7 instead of 5 fields.

The following functions are now marked deprecated in source:
* mysql_list_dbs
* mysql_list_tables
* mysql_list_processes

Various coverity scan fixes, including CONC-452 and CONC-453.
Special thanks to Lukas Javorsky for fixing numerous covscan
issues (This patch includes part of his pull request #126).

Coverity scan build was using the following cmake parameters:
-WITH_EXTERNAL_ZLIB=ON -DWITH_UNIT_TESTS=OFF.

CWE-416 (use after free) in dtoa.c (from netlib) is still open.
