Mikhail Chalov 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.
