Changes in V4:
- Added missing calls to config_get_double() for:
  "pi_integral_exponent"
  "pi_integral_norm_max"
  "pi_integral_scale"
  "pi_proportional_exponent"
  "pi_proportional_norm_max"

Changes in V3:
- Reduced interface to two types, double and int
  (enums are accessed like ints)
- Converted almost everything

Changes in V2:
- API is much simpler to use
- numerous details in the implementation have been improved
- half dozen legacy options converted

Now this series passes the linuxptp-testsuite.  I pushed the branch to
github in the hopes that people will pull and test it.

  repo:    g...@github.com:richardcochran/linuxptp-as.git
  branch:  config-v4

(BTW buggy branch config-v3 has been deleted from github.)

Patches 1-4 and 12 provide changes allowing passing of the configuration.
Patches 5 and 6 add a simple hash table.
Patch 7 adds the bulk of the new implementation.
Patch 8 lets the UDP transport use the new TTL option.
Patch 13 adds a way to "lock" options from the command line.
Patch 37 cleans up a useless variable.
Patch 54 removes a now empty structure.
Patch 62 adds enumerated types.
Patch 69 tweaks ptp4l's logging configuration.

All the *other* patches convert individual options.

Review and comments are most welcome.

Thanks,
Richard
