this patch uses grep to test whether the net_tstamp.h header has
HWTSTAMP_TX_ONESTEP_SYNC flag defined. If it doesn't then we can simply define
it with the correct value. This works because proper drivers should just report
that the value is not allowed if they don't support onestep mode. This is the
cleanest way to ensure that linuxptp will still work on kernels which have not
defined the one step flag, and also works for any distributions which backport
the feature.

Ever since upgrading to Debian 7.0, building linuxptp results in an
annoying error message. This is due to the fact that the directory
/usr/include/bits is no longer present, but our makefile expects it
to exist. This patch fixes the issue by telling grep not to complain
about missing files.

Add new options to ptp4l and phc2sys to print summary statistics of the
clock instead of the individual samples.
[ RC - Fix () function prototype with (void).
- Use unsigned for sample counter.
- Fix over-zealous line breaks. ]

Add a new option to wait for ptp4l to be in a synchronized state.
Periodically check PORT_DATA_SET and wait until there is a port in
SLAVE, MASTER or GRAND_MASTER state. Also, set the default
synchronization offset according to the currentUtcOffset value from
TIME_PROPERTIES_DATA_SET and the direction of the clock synchronization.

We use the PTP_SYS_OFFSET ioctl method in preference to doing
clock_gettime from user space, the assumption being that the kernel space
measurement will always be more accurate.

This patch adds support for sk_interface_phc to lookup the /dev/ptpX device
using ethtool's get_ts_info ioctl
-v2-
* set ethdev to null initially
* rebased on top of phc2sys changes
-v3-
* fixed typo regarding slash

This is really just a first attempt using a hard coded length. Probably
it will be necessary to let the length be configurable and/or adaptable.

We can pre-compute a table of suitable values in order to simplify the
run time random delay selection.

Since the master implementation is still lacking, we will just keep
the slave-only flag hard coded for now.

This commit also introduces clock and port objects, but only with the
minimal interface needed by the BMC.
