overload libc memory allocators with custom ones to trace all allocations (#13810)
* overload libc memory allocators with custom ones to trace all allocations
* grab libc pointers for external c plugins
* use -ldl when necessary; fallback to work without dlsym when it is not available
* initialize global variable
* add optional dl libs
* dynamically link every library function when needed for the first time
* prevent crashes on musl libc
* another attempt
* dont dereference function
* attempt no 3
* attempt no 4
* cleanup - all attempts failed
* dont enable tracing of allocations
* missing parenthesis
