lib/uri/rfc2396_parser.rb (initialize): reduce bytecode size

Reduce the initialize method from 2088 to 1332 bytes on 32-bit x86
Measurement obtained using `memsize_of_all', as `memsize_of'
is non-recursive:

  a = ObjectSpace.memsize_of_all(RubyVM::InstructionSequence)
  RubyVM::InstructionSequence.compile(src)
  b = ObjectSpace.memsize_of_all(RubyVM::InstructionSequence)
  p(b - a)


In the future, it may be able to make the bytecode compiler perform this
optimization transparently for existing code.  However, I also like the
shorter &:method syntax.

I'll commit in a few days unless there's an objection.
