erts: Refactor binary allocation interface to also initialize Binary

except the reference counter 'refc', as different callers
have different strategies regarding the lifetime of the binary.
erts: Fix gdb command etp-carrier-blocks for 32-bit
Remove untested option 'generic_debug' from gen_server

This undocumented option makes an init:get_argument/1 call every time a gen_server
is started.
