BUG#: 9470
TITLE: Fix some missing error handling in MOF Compiler and added compiler tests

DESCRIPTION: Added error tests for pragma, qualifierDecl, etc. in Compiler.
Added error tests in Compiler/tests/invalidMOF directory.  Moved some
tests from Compiler/tests/qualifierDecl to invalidMOF dir

   to get around the problem that arrays having strings

/* ATTN: KS 20 Feb 02 - Think we need to account for NULL value here differently
   They come in as an empty string from devaultValue and if they are an empty
   string we need to create the correct type but without a value in it.
   Easiest may be to test in each converter since otherwise would have to
   create a second switch. Either that or if strlength = zero
   create an empty CIMValue and then put in the type
                CIMValue x;
