dbe39f14fe MDEV-28762: recursive call of some json functions without stack control 
Analysis: Some recursive json functions dont check for stack control
Fix: Add check_stack_overrun(). The last argument is NULL because it is not
used

5a9df1550f MDEV-23941: strings/json_lib.c:893:12: style: Suspicious condition 
The characters parsed are always ascii characters, hence one byte. This
means that the code did not have "incorrect" logic because the boolean
condition, if true, would also evaluate to the value of 1.

The condition however is semantically wrong, assuming a length is equal
to the condition outcome. Change paranthesis to make it also read
according to the intent.

6ac2a35553 MDEV-19628 JSON with starting double quotes key is not valid. 
First character of the key name is just skipped, so the escapement
wasn't handled properly.

4aaa38d26e Enusure that my_global.h is included first 
- Added sql/mariadb.h file that should be included first by files in sql
  directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables
  that must be done before my_global.h is included)
- Removed a lot of include my_global.h from include files
- Removed include's of some files that my_global.h automatically includes
- Removed duplicated include's of my_sys.h
- Replaced include my_config.h with my_global.h

7c7c0696e7 MDEV-11856 json_search doesn't search for values with double quotes 
character (").

        The my_wildcmp function doesn't expect the string parameter to
        have escapements, only the template. So the string
        should be unescaped if necessary.

check_contains() fixed. When an item of an array is a complex
        structure, it can be half-read after the end of the recursive
        check_contains() call. So we just manually get to it's ending.
