Added basics of parsing, without actual object generation.
Lexer errors to return -1 rather than exit.
Add more consistent error stuff, add in object creation stuff.
Preparation for including into Perl module.
Fixed most of the links for creation of objects and arrays.

Next step is to test this.
Change constants, test json output, errors.c made by makefile, key on stack.

Remove old json_true, json_false, json_null.

Put "polish" routine into test code of parser.c to print out the parsed item.

Preserve current key on stack.

Automate inclusion of errors.
Fixups to pass tests for Perl version.
Remove bison grammar and pull-in in Perl directory.
Merge branch 'no-bison'
