- The XS version of Params::Validate did not work if a spec hash
reference was marked Readonly using Readonly::XS.

- Added some tests for using tied values for params or spec, and
discovered that a tied spec causes a segfault, but could not figure
out how to fix this (Grr, Perl magic is a huge pain in the nether
regions).
