Update lang/erlang{,-doc,-man} to 19.2.

Erlang/OTP 19.2 is the second service release for the 19 major release.
The service release contains mostly bug fixes and characteristics
improvements.

Some highlights for 19.2

* STDLIB: The new behaviour gen_statem has been improved with 3 new
  features: the possibility to use old style non-proxy timeouts
  for gen_statem:call/2,3, state entry code, and state
  timeouts. These are backwards compatible. Minor code and
  documentation improvements has been performed including a
  borderline semantics correction of timeout zero handling.

* SSL: Experimental version of DTLS. It is runnable but not complete
  and cannot be considered reliable for production usage. To use
  DTLS add the option {protocol, dtls} to ssl:connect and ssl:listen.

* SSH: Extended the option silently_accept_hosts for ssh:connect to
  make it possible for the client to check the SSH host key
  fingerprint string. Se the reference manual for SSH.

* ~40 contributions since the previous service release OTP 19.1
