Update more link-layer dissectors to void functions

brcm_tag_if_print()
brcm_tag_prepend_if_print()
dsa_if_print()
edsa_if_print()
ether_if_print()
netanalyzer_if_print()
netanalyzer_transparent_if_print()

Update ether_print(), ether_common_print() and ether_switch_tag_print()
to void functions.

Add a flag parameter to ether_print(), ether_common_print() and
ether_switch_tag_print() to increment the link-layer header length field
of the netdissect_options when needed.
The calls use TRUE when the return value of the funtions was used.
The calls with FALSE avoid increments when the calls are nested.

Moreover:
Remove trailing "_if" from some protocol names.
