ntp: re-enable server debugging and control by PACKAGECONFIG

The description in a previous patch to disable debugging is incorrect.
Although the option is default-enabled in configure.ac, configure does
respect the option that disables it.

In ntp 4.2.7 the option code is refactored to ntp_debug.m4 and has an
effect in sntp as well.  Adding --disable-debugging to the top-level
configure options overrides the default for both 4.2.6 and 4.2.7 without
patching the distribution.

Make the selection explicit and configurable, but restore the historical
default.  Absence of debugging capability in the server makes it
difficult to validate complex configurations.

pps-tools: add recipe

This provides some utilities and a user-space header necessary to use
the Linux KPPS (RFC 2783) capabilities of gpsd and ntp.

gpsd: add deterministic support for KPPS interface

gpsd enables low-precision PPS (pulse-per-second) support by default,
but only includes the high-precision kernel API capabilities if
sys/timepps.h is also detected.  Under Linux the pps-tools package
installs this header.  Remove the feature non-determinism and increase
gpsd capabilities by adding an explicit dependency.

ntp: add deterministic support for KPPS interface

ntp checks for presence of sys/timepps.h to determine whether the kernel
supports the RFC 2783 KPPS interface.  Under Linux the pps-tools package
installs this header.  Without this feature the ATOM clock driver does
not work, and other drivers like NMEA have reduced precision.  Remove
the feature non-determinism and increase ntpd capabilities by adding an
explicit dependency.
