- fixed some bugs in StackWalk (claimed for but forgotten in last 

patch)
- removed location field in symt_data, and reworked the actual
  location of information based on the 'kind' field
- shorten debug channel name
- added support for bitfield in struct:s
- cleaned up source line information support
- now storing constants values as VARIANT
