Fixes warnings like:
```
unittest/libmariadb/bulk1.c: In function ‘bulk1’:
unittest/libmariadb/bulk1.c:77:43: error: ‘calloc’ sizes specified with ‘sizeof’ in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
77 | lengths= (unsigned long *)calloc(sizeof(long), TEST_ARRAY_SIZE);
| ^~~~
unittest/libmariadb/bulk1.c:77:43: note: earlier argument should specify number of elements, later size of each element
unittest/libmariadb/bulk1.c:78:39: error: ‘calloc’ sizes specified with ‘sizeof’ in the earlier argu
ment and not in the later argument [-Werror=calloc-transposed-args]
78 | vals= (unsigned int *)calloc(sizeof(int), TEST_ARRAY_SIZE);
| ^~~
```
The calloc prototype is:
```
void *calloc(size_t nmemb, size_t size);
```
So, just swap the number of members and size arguments to match the
prototype, as we're initialising N struct of size Y. GCC then sees we're not
doing anything wrong.

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.
Plugin configuration happens now in CMakeLists.txt files in corresponding plugin directories.
plugins.cmake now contains REGISTER_PLUGIN_FUNCTION which accepts the following parameters:
- TARGET: the name of the plugin (dynamic plugins will be named ${TARGET}.so (or .dll)
- SOURCES: source files
- LIBRARIES: additional libraries for linking
- INCLUDES: include directories
- CONFIGURATIONS: possible plugin configurations: valid arguments are DYNAMIC, STATIC, OFF
- DEFAULT: default configuration (see CONFIGURATIONS)
- COMPILE_OPTIONS: compiler flags
The default plugin configuration can be specified via cmake parameter -DCLIENT_PLUGIN_${TARGET}=[DYNAMIC|STATIC|OFF]
- changed plugin API to avoid crashes: Oracle/MariaDB changed
structure several times without updating interface version.
- ABI fixes: moved additional net items to net->extension (connection
handler and com_multi buffer)
This will allow to read and import data from remote locations, e.g.
LOAD DATA LOCAL INFILE 'htp://www.example.com' or
mysql_options(mysql, MYSQL_READ_DEFAULT_FILE, "http://localhost/test.cnf");
The implementation uses libcurl. For a list of supported URL types
