Ruby 1.9.3+-only cleanups

unicorn 5 will only support Ruby 1.9.3 and later, so remove
some checks for Hash#compare_by_identity and IO.copy_stream
which we know exist in Ruby 1.9.

Favor &:sym proc dispatch to avoid unnecessary captures and
bytecode size increases, too.

Finally, ensure we fail fast by converting some literal
hashes to use non-arrow syntax for symbolic keys.
