- Avoid implicit comparisons in conditionals.
- probe.c:get_num_probes_with_pops function renamed to exists_probes_with_pops.
- Some #defines have been replaced by enums.
- Missing documentation comments for functions and enum entries added.
- Code parsing probe linespecs factorized into a new function.
- The gdbarch function dtrace_probe_argument has been renamed to
  dtrace_parse_probe_argument.
- Other minor changes suggested in the mailing list.]

This patch series introduces support in GDB for a new type of probe:
DTrace USDT probes.

The first three patches do some changes to the existing probe.[ch]
code, fixing some minor problems associated to support several probe
types, having several probes of different types defined in the same
object and supporting the notion of enabling and disabling probes.

The rest of the patches are the implementation of the new probe type,
including target support for x86_64 targets, a testsuite and
documentation.

Tested on x86_64-*-linux-gnu.
No visible regressions.

Jose E. Marchesi (9):
  Adapt `info probes' to support printing probes of different types.
  Move `compute_probe_arg' and `compile_probe_arg' to probe.c
  New commands `enable probe' and `disable probe'.
  New gdbarch functions: dtrace_parse_probe_argument,
    dtrace_probe_is_enabled, dtrace_enable_probe, dtrace_disable_probe.
  New probe type: DTrace USDT probes.
  Support for DTrace USDT probes in x86_64 targets.
  Simple testsuite for DTrace USDT probes.
  Documentation for DTrace USDT probes.
  Announce the DTrace USDT probes support in NEWS.
