Provide a callback after socket creation, use _Bool

The callback is provided to set socket options, instead of individual
options such as path_mtu_discovery (which is now removed).

Noticed that the Rust rexmpp structure's C representation does not
match that of C, since Rust's "bool" maps to C99's "_Bool", while I
thought that it maps to "int" (c_int). Adjusted C structures to use
"bool" from stdbool.h as well, since C99 (GNU99) is used already.
