Fixes the following security issues:
- CVE-2021-41105: FreeSWITCH susceptible to Denial of Service via invalid
SRTP packets
When handling SRTP calls, FreeSWITCH is susceptible to a DoS where calls
can be terminated by remote attackers. This attack can be done
continuously, thus denying encrypted calls during the attack.

- CVE-2021-41157: FreeSWITCH does not authenticate SIP SUBSCRIBE requests by default
By default, SIP requests of the type SUBSCRIBE are not authenticated in
the affected versions of FreeSWITCH.

- CVE-2021-37624: FreeSWITCH does not authenticate SIP MESSAGE requests,
leading to spam and message spoofing
By default, SIP requests of the type MESSAGE (RFC 3428) are not
authenticated in the affected versions of FreeSWITCH. MESSAGE requests
are relayed to SIP user agents registered with the FreeSWITCH server
without requiring any authentication. Although this behaviour can be
changed by setting the auth-messages parameter to true, it is not the
default setting.

- CVE-2021-41145: FreeSWITCH susceptible to Denial of Service via SIP flooding
When flooding FreeSWITCH with SIP messages, it was observed that after a
number of seconds the process was killed by the operating system due to
memory exhaustion

- CVE-2021-41158: FreeSWITCH vulnerable to SIP digest leak for configured gateways
An attacker can perform a SIP digest leak attack against FreeSWITCH and
receive the challenge response of a gateway configured on the FreeSWITCH
server. This is done by challenging FreeSWITCH's SIP requests with the
realm set to that of the gateway, thus forcing FreeSWITCH to respond with
the challenge response which is based on the password of that targeted
gateway.
