remove the 'name_coff' parameter in dns_name_towire()

Browse Source 
this parameter was added as a (minor) optimization for
cases where dns_name_towire() is run repeatedly with the
same compression context, as when rendering all of the rdatas
in an rdataset. it is currently only used in one place.

we now simplify the interface by removing the extra parameter.
the compression offset value is now part of the compression
context, and can be activated when needed by calling
dns_compress_setmultiuse(). multiuse mode is automatically
deactivated by any subsequent call to dns_compress_permitted().
