[chrony-dev] timepps.h and chrony

[Bill Unruh <unruh@xxxxxxxxxxxxxx>]

Perhaps it would be a good idea to include the file timepps.h into the chrony
source files, and use it instead of the one that is supposed to be in
/usr/include. 
a)It seems on a variety of systems, timepps.h is in a variety of places 
(eg /usr/include/linux instead of /usr/include where chrony looks for it. ntp
in their source code has their own version which looks for timepps.h in a
variety of possible places. chrony might do the same)
b) timepps.h does not seem to be included in at least some distributions which
have the pps_core etc modules and thus support the pps api. For those it would
be good to have timepps.h in the chrony sources.

Ie, the refclock drivers could look for chrony-timepps.h locally which looks
in /usr/include, /usr/include/linux and finally locally in the chrony sources.

I ran into this with Mandriva 2010.x and 2011 which has the pps_core but does
not have the timepps.h anywhere. Of course what happened was that configure
found that the test program did not compile and simply removed the pps as an
option. 
This is compounded by the fact that earlier versions of Mandriva have pps_core module but
did not even have /usr/include/linux/pps.h 
But it would seems that pps.h is pretty useless without timepps.h as well, but
I may be wrong.
