Fixes#1266
According to RFC 5766, [section 6.2](https://www.rfc-editor.org/rfc/rfc5766#section-6.2) point no. 5, the turn server needs to reject the request with 508 (Insufficient Capacity) error code when the given RESERVATION-TOKEN is not valid.
For our deployment, it is useful if coturn returns a valid HTTP response to an HTTP request. To do this on the same port as STUN/TURN and without enabling the admin site, I have extended `read_client_connection()` to return a canned HTTP response, in response to an HTTP request, rather than immediately closing the connection.
Fixes#1259
If `ur_string_map_put ` fails then the string that was just `strdup`-ed
will leak memory
Now the return value is checked and memory free-ed in case of failure
- srandom/random provide stronger randomness characteristics than
srand/rand in some operating systems.
- usage of srand/rand is not very consistent in coturn.
There is room for more refactoring and use apputils helper functions in
ns_turn_msg.c too but i'm not sure that dependency from "client" module
to "apps" module is a good idea yet.
Thx @0xdea

Add missing checks for length of realm/nonce/server_name before copying
those values to the buffer passed to stun_is_challenge_response_str.
The function stun_is_challenge_response_str is only used in uclient test
application.
Thank you very much @0xdea

I tested the code part by using manual and automated tools for more than
2 years.
Fixes#823
When you try to delete an alternate server in the list by using "das :" command on the CLI, the session gets stuck and can't response although alternate server is removed.
The problem appears to be related to calling del_alt_server function in the same function recursively.
