The one user of the function, posix_clock_open(), simply open codes
the closing call to phc_close(). This patch provides a method to
balance closing and opening of a posix clock. In addition, the
phc_ctl program never explicitly closed the opened clock, and so this
patch adds the missing call.

The two programs, phc2sys and phc_ctl, use nearly identical subroutines to
open an instance of a dynamic posix clock. In anticipation of yet a third
program with similar needs, this patch refactors the common code into the
utilities.

The kernel supports different PTP_SYS_OFFSET* ioctls. Use the sysoff
enum to allow selecting between them in sysoff_measure().

When parsing the argument, the minimum value should be -DBL_MAX instead
of DBL_MIN, which is the smallest positive value.

This is an updated version of a script I wrote a couple years ago for
debugging the PHC when writing a new driver. I figured that it might be
handy for the LinuxPTP project to include, as it can give some insight
into the PHC directly. I have updated it to make use of the shared code
here, in order to reduce duplication. Hopefully this is of some use to
everyone.
