All the link-layer dissectors are now void functions.
All the functions were moved to the void_printers[] array.
Rename this array to printers[].
Remove the uint_printers[] array, now empty.
Remove the 'ndo_void_printer' flag field, now useless, from
netdissect_options.
Remove other transitional code.
Currently the return value of link-layer dissectors is supposed to be
the length of the link-layer header, so that it can be skipped for -x
and -X.
If a link-layer dissector or a called function throws an exception, it
returns no value, so that length isn't available.
The goal is to change all the link-layer dissectors to be void functions
and dissectors should update a new field of the netdissect_options
structure "link-layer header length" rather than returning it as a value.
In this transition process, the link-layer dissectors will be moved, when
updated, from the uint_printers[] array (named before printers[]) to the
void_printers[] array.
In this transition process, a new field of the netdissect_options
structure, ndo_void_printer (TRUE/FALSE), set in the updated function
lookup_printer(), will permit to choose between the old and new way to
update the link-layer header length.
Using seconds offset from GMT to local time to compute local time give
errors when printing times outside the same daylight saving time period.
Use the localtime() function for default and -tttt cases.
Use the gmtime() function for -ttt and -ttttt cases.
Rename ts_hmsfrac_print() to ts_date_hmsfrac_print().
Remove some variables now useless.
Update some comments.
The structure 'netdissect_options' can hold if_printer.
Thus the structure 'print_info' is useless now.
Moreover:
Delete useless blank lines
Fix indent
