96af0ad by Guy Harris (guy@xxxxxxxxxxxx):
Add some length checks, remove a DISSECTOR_ASSERT().
Do more checks to make sure we don't run past the end of the data we're
handed, and don't do a DISSECTOR_ASSERT(), as there may well be packets
that don't have enough data to pass the assertion - that was causing
some errors to show up in the 2.6 buildbot when doing 802.11 decryption
tests. Those errors should instead be reported as "sorry, we can't do
decryption" errors by the decryption code.
(XXX - the 802.11 *dissector* should probably be extracting the relevant
fields and doing the relevant checks, and hand the data to the
decryption code, so that we don't duplicate 802.11 frame parsing with
code that might not do as much necessary work as the 802.11 dissector.)
Tweak some comments while we're at it.
