The patch ensures that non-duplicate subnets are appended to the end of the

element previously, the memory for it was effectively leaked.
It also allows /32 "subnets", even though arguably the hosts file should be
used instead, but now the test in read_subnets_file() matches the assert in
subnet_entry_set().

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.

The capture for bug 10078 caused the buildbot to time out; callgrind revealed an
enourmous amount of time being spent looking up ethernet addresses. The previous
code cast each address (6 bytes) to a guint64 (8 bytes) then used the built-in
g_int64_hash. Unfortunately, g_int64_hash is an *awful* hash function - it
produces a 4-byte hash by simply discarding the upper 4 bytes of its input.
For the capture file in question this strategy (which effectively ignores the
upper two bytes of each ethernet address) produced an astounding number of
collisions, leading to the terrible running-time.
Use wmem_strong_hash directly on the 6-byte address instead, which saves us a
bunch of useless casting and bit-twiddling and produces a much better hash
distribution. This shaves 20% off the time to tshark-with-tree the capture file
in question *despite* a substantially more expensive hash function
(wmem_strong_hash is not exactly fast compared to g_int64_hash).
