[gpsd-dev] revert commit d1965788249d7e22cdde4021d452cf0dc6c6b9bd

[Gary E. Miller]

Yo All!

My git head was broken by commit d1965788249d7e22cdde4021d452cf0dc6c6b9bd.

It breaks my build on Gentoo running gcc 4.9.2
    
    libgps_shm.c: In function 'int gps_shm_read(gps_data_t*)':
    libgps_shm.c:122:12: error: no match for 'operator=' (operand types are
    'gps_data_t' and 'volatile gps_data_t')
      noclobber = shared->gpsdata;
                ^
    libgps_shm.c:122:12: note: candidate is:
    In file included from gpsd.h:350:0,
                     from libgps_shm.c:30:
    gps.h:1918:8: note: gps_data_t& gps_data_t::operator=(const gps_data_t&)
     struct gps_data_t {
            ^
    gps.h:1918:8: note:   no known conversion for argument 1 from 'volatile
    gps_data_t' to 'const gps_data_t&'

I just reverted it, the whole thing.  The commit touched several files,
Most of the commit is probably good, so Zbigniew needs to split that up
into smaller commits to allow us to troubleshoot it.
