Evgeniy Khramtsov fd8e07af47 Get rid of ejabberd.hrl header 
The header consisted of too many unrelated stuff and macros misuse.
Some stuff is moved into scram.hrl and type_compat.hrl.
All macros have been replaced with the corresponding function calls.

TODO: probably type_compat.hrl is not even needed anymore since
we support only Erlang >= OTP 17.5
