	* cs-parser.jay: FIRST_KEYWORD, LAST_KEYWORD: used to know if a
	token was a keyword or not.

	Add `error' options where an IDENTIFIER was expected;  Provide
	CheckToken and CheckIdentifierToken convenience error reporting
	functions.

	Do not use `DeclSpace.Namespace', use `DeclSpace.NamespaceEntry'.

	* decl.cs: Rename `NamespaceEntry Namespace' public field into
	NameSpaceEntry NameSpaceEntry.

	(LookupInterfaceOrClass): Avoid creating a full qualified name
	from namespace and name: avoid doing lookups when we know the
	namespace is non-existant.   Use new Tree.LookupByNamespace which
	looks up DeclSpaces based on their namespace, name pair.

	* driver.cs: Provide a new `parser verbose' to display the
	exception thrown during parsing.  This is turned off by default
	now, so the output of a failure from mcs is more graceful.

	* namespace.cs: Track all the namespaces defined in a hashtable
	for quick lookup.

	(IsNamespace): New method
