2ff01e763e Fix insecure use of strcpy, strcat and sprintf in Connect
Old style C functions `strcpy()`, `strcat()` and `sprintf()` are vulnerable to
security issues due to lacking memory boundary checks. Replace these in the
Connect storage engine with safe new and/or custom functions such as
`snprintf()` `safe_strcpy()` and `safe_strcat()`.

With this change FlawFinder and other static security analyzers report 287
fewer findings.

567b681299 Minimize unsafe C functions usage - replace strcat() and strcpy() (and strncat() and strncpy()) with custom safe_strcat() and safe_strcpy() functions
The MariaDB code base uses strcat() and strcpy() in several
places. These are known to have memory safety issues and their usage is
discouraged. Common security scanners like Flawfinder flags them. In MariaDB we
should start using modern and safer variants on these functions.

This is similar to memory issues fixes in 19af1890b5
and 9de9f105b5 but now replace use of strcat()
and strcpy() with safer options strncat() and strncpy().

However, add '\0' forcefully to make sure the result string is correct since
for these two functions it is not guaranteed what new string will be null-terminated.

Example:

    size_t dest_len = sizeof(g->Message);
    strncpy(g->Message, "Null json tree", dest_len); strncat(g->Message, ":",
    sizeof(g->Message) - strlen(g->Message)); size_t wrote_sz = strlen(g->Message);
    size_t cur_len = wrote_sz >= dest_len ? dest_len - 1 : wrote_sz;
    g->Message[cur_len] = '\0';

-- Reviewer and co-author Vicențiu Ciorbaru <vicentiu@mariadb.org>
-- Reviewer additions:
* The initial function implementation was flawed. Replaced with a simpler
  and also correct version.
* Simplified code by making use of snprintf instead of chaining strcat.
* Simplified code by removing dynamic string construction in the first
  place and using static strings if possible. See connect storage engine
  changes.

19af1890b5 Use memory safe snprintf() in Connect Engine
This commit replaces sprintf(buf, ...) with
snprintf(buf, sizeof(buf), ...),
specifically in the "easy" cases where buf is allocated with a size
known at compile time.

The changes make sure we are not write outside array/string bounds which
will lead to undefined behaviour. In case the code is trying to write
outside bounds - safe version of functions simply cut the string
messages so we process this gracefully.
