Subject: Compile everything with "-W -Wall -Wno-unused-parameter" flags
 (#1276)

Fix all the warnings.

Getting rid of "-Wno-unused-parameter" is quite complex because some
parameters usage depends on compilation variable (i.e.
`--enable-debug-messages`).

The "-Werror" flag has been added only in Travis builds to avoid
breaking the builds to users using uncommon/untested
OS/compiler/enviroment.

Tested on:
* x86_64; Ubuntu 20.04; gcc 7,8,9,10,11; clang 7,8,9,10,11,12
* x86_64; CentOS 7.7; gcc 4.8.5 (with "--disable-gcrypt" flag)
* Raspberry 4; Debian 10.10; gcc 8.3.0
