leave dumpcap installed without enhanced privileges, so the underlying

NDPS dissector is also the poster child for not being considered "that naughty" by checkAPIs because most of its proto_tree_add_text calls don't have printf-style arguments (which is what checkAPIs really keys off of)
Fixed both cases and removed about 370 proto_tree_add_text calls from the dissector.

it will fail, rather than silently (other than a message you might miss)
ignoring the request for setuid installation. See bug 10246.

if you ask for setuid or setcap installation of dumpcap, but
dumpcap isn't built, it'll let you know that there's nothing to
make setuid/setcap, and fail;
if you ask for setcap installation of dumpcap, but setcap wasn't

fail;
so that it won't silently (other than a message you might miss) ignore

As Anders correctly pointed out in I7d8f84b2e, constantly resetting state will
turn init_dissection into a bit of a hot path. Especially as we will already
bear the overhead of switching files, we don't want to fall any further behind
than we have to.
This change includes three unrelated optimizations that reduce the cost of
init_dissection by about 40% as measured by callgrind:
- only initialize ares/ADNS if that preference is enabled (this of course only
applies if you specify -n to tshark or otherwise disable the preference)
- use memcpy instead of a loop in sigcomp UDVM init
- use memcpy instead of a loop in bootp dissector
The only remaining obvious hot spot in this path is reassembly_table_init since
it is called by so many dissectors. Suggestions (perhaps to get rid of the
GPtrArray) welcome.
Oh, and one other change to use g_strerror instead of strerror as insisted
upon by the API pre-commit hook.

TShark relies on dumpcap to capture packets, and TFShark doesn't even do
packet capturing (it dissects files, not network traffic), so neither of
them need, or should run with, special privileges. If you *must* run
with special privileges in order to capture, grant those privileges to
dumpcap, which has a *lot* fewer lines of code than libwireshark and
TShark/TFShark.
