Fixed most compiler warnings -Wall -Wextra

repro:
  CFLAGS="-Wall -Wextra -Wunused-parameter -Wc++-compat" ./configure && make

which we use for perl, and libyaml is now included in cperl.
Tested with gcc-5 and clang-3.7

There are still a tons of format warnings (%d on 64bit) in
example-deconstructor.c which I skipped.
