[PATCH v2 0/5] Non-contiguous address range bug fixes / improvements

This five part series fixes some bugs associated with GDB's non-contiguous
address range support.

Differences from v1 can be summarized as follows:

- Big block of code in stack.c which handled "certain pathological cases"
  was removed entirely.  Both Tom and Pedro suggested this change.
- Changes to printcmd.c split out into separate patch; patch expanded
  to allow use of data associated with minimal symbol in certain (rare)
  cases.  (But perhaps not especially rare when dealing with
  non-contiguous address ranges.)
- Commit log for negative offset patch expanded with better examples.
- Tests revised slightly to not fail due to change in functionality.

I see no regressions when testing on F30 / x86_64.

Kevin Buettner (5):
  Prefer symtab symbol over minsym for function names in non-contiguous
  Restrict use of minsym names when printing addresses in disassembled
  dwarf2-frame.c: Fix FDE processing bug involving non-contiguous ranges
  Allow display of negative offsets in print_address_symbolic()
  Improve test gdb.dwarf2/dw2-ranges-func.exp
