These changes have no effect at this point, but are the initial steps
introducing host builds. Some changes are minor cleanups, some depend
on CONFIG_HOST_PROCESS which is not defined at this point.

The compiler is smart enough to turn this into a multiplication by 8:

    cf54:       3d c1 00 03     sli r1,r14,3
    cf58:       59 a1 00 00     sw (r13+0),r1

and any real division by ll would be trapped by ./check-error.c .

Still, I'd better simplify the code.

This removes TRACE_DEV(), turning it into pll_verbose() and wrc_verbose().

The functions are enabled and disabled by kconfig, with defaults matching
the previous behaviour.

So nothing changes, but the binary is smaller because the previous
wrc_debug_printf() was silent because of a run-time conditional
(though hardwired false at build time). The condional is now at build
time.  We save around 2k, between strings and calling code, in
all wrc builds (nothing is saved in wrs, which is verbose by default,
nor in devel_build_test_defconfig where all verbose options are on)).

This time I added -Wmissing-prototypes and fixed accordingly. Again, this
used to be part of -Wall and I'm disgusted by it not being so any more.

What does "all" mean, then?

This is a bigger change than expected, as the width was defined
in two places. So I moved the definition in <wrc.h>, whence everybody
picks it.

When WR PTP Core is set in GrandMaster mode it aligns its nanosecond
counter to 1-PPS and 10MHz coming from external source. When user wants
to set seconds counter to a desired value (with _time set_ command), the
nanosecond counter was also set (zeroed) causing additional (random)
offset to the external source. The commit adds _time setsec_ and _time
setnsec_ for setting only seconds or nanoseconds counter without
affecting the other one. Now, when user wants to set current time on a
GrandMaster Node he has to call _time setsec_ command after _mode gm_

This adds copyright notes to all non-trivial source files,
unless they where already there (i.e. dev/endpoint.c alone).

I found authorship using the following script, run on commit "a2721762
documentation updated" (i.e, before automatic reindentation and other
trivial stuff by me):

  git grep -l . | grep -v sockitowm/ | \
  while read F; do
       echo "##### $F"
       git blame -w $F | \
         sed -e 's/^[^ ]* .//' -e 's/-[0-9][0-9]-[0-9][0-9] .*$//' | \
         sort | uniq -c | sort -rn
  done

Then I augmented each file with this boilerplate:

Then I removed all the lines that didn't apply. Sometimes I reordered
the authors to reflect who is the main author.

This is massive: 4k lines changed (but only 840 if you ignore
space-only changes).  In this case "git blame -w" won't always find
the right patch, and it may fall on this patch -- because those
800 lines changed in content too.

This has been done with

   find . -name '*.[ch]' | xargs -n 1 ./scripts/Lindent

Statistics: all changes and ignoring blank space:

   morgana% git diff --stat HEAD~1 | tail -1
    77 files changed, 3774 insertions(+), 3709 deletions(-)
   morgana% git diff -w --stat HEAD~1 | tail -1
    61 files changed, 894 insertions(+), 829 deletions(-)

However, after this step I hand-fixed some very ugly long expressions
(leaving them long: no content change at all is there).

If you find this patch with "git blame" please use "git blame -w"
to have all white-space ignored while associating lines to commits.

This commit has no practical effect but cleanup. I made it
with sed like this:

  git grep -l '[ \t]$' | xargs sed -i 's/[ \t]*$//'

However, I had to manually restore doc/wrpc_mon.png after the fact.
Similarly, I restored the include/hw/*regs.h files, as they
are (most likely) auto-generated.

The high 24 bits are HDL don't care values.
Reading them into the timestamp caused locking issues under Altera.

rewrote pps_gen driver (to match the libswitchhw one), removed remaining references to UTC timescale
