Fixes a number of places where literal, non-dynamic strings are used as the first argument for constant and instance variable get, set, and defined? methods. This reduces object overhead in all cases.

Notable fixes:

  • Setting @original_filename and @content_type in read_multipart (cgi/core.rb). This is called for every multipart read.
  • Setting @uri and @ref in DrbObject.new_with (drb/drb.rb). Called for every "with" instantiation of a DrbObject.
  • Setting BINDING_QUEUE in IRB::Workspace#initialize (irb/workspace.rb). Called for every new IRB workspace.
  • Getting @mon_mutex in ConditionVariable#wait (monitor.rb). Called for every #wait. This fix makes the method require zero object allocation (other than imposed by the runtime).

The other fixes are rarely called, but fixed for consistency.

make test-all passes the same with or without this patch.

I'm sorry, I should have added 'patch by Charles Nutter' to the commit log but I forgot that although git can track authors, svn does not.
