[PATCH 0/9] Convert breakpoint iteration macros to ranges

[Simon Marchi via Gdb-patches <gdb-patches@sourceware.org>]

This all started with me finding that the update_global_location_list
function was hard to read, notably because the breakpoint iteration
macros are a bit hard to read (require multiple local variables and
pointers to pointers).  So this removes all breakpoint-related iteration
macros in favor of functions that return iterable ranges.

Patch 5 also converts the bp_locations array into a vector, which
simplifies things a bit.

In the end, the update_global_location_list is still hard to understand
(big surprise), but I think that the code in general is a bit tidier
like this.

I regtested this on Linux, with the unix and native-extended-gdbserver
boards.

Simon Marchi (9):
  gdb: add all_breakpoints function
  gdb: add all_breakpoints_safe function
  gdb: add all_tracepoints function
  gdb: add breakpoint::locations method
  gdb: make bp_locations an std::vector
  gdb: add all_bp_locations function
  gdb: add all_bp_locations_at_addr function
  gdb: remove iterate_over_breakpoints function
  gdb: remove iterate_over_bp_locations function
