Since DTLS and TLS do not differ in handling ClientKeyExchange and
ServerKeyExchange, its dissection got moved to ssl-utils. The code is
based on the SSL dissector, with header field names adjusted to the
DTLS ones (those got capitalized). Besides a version difference (for
signatures), the header field and function names, the DTLS and SSL code
are equal (this is verified).
This patch refactors the dissectors for DHE_RSA and ECDHE to make use of
a common function to dissect the signed_params field. All offset
tracking is also removed in favor of exception handling by the
proto_tree_add_item function. Occurrences of proto_tree_add_uint are
also replaced by proto_tree_add_item for simplicity.
After those changes, the SKE dissector for DH key exchanges is updated
to handle the mandatory signature field in TLSv1.2, using the newly
added function. (bug 9208)
Another bug occurred after the length check removal, pre-TLS and
OpenSSL's old DTLS implemenation do not include a vector length in
the CKE. This is now also fixed. (bug 10222)
Other minor changes: comments added/corrected, renamed
keyex_dh -> keyex_dhe (includes DHE_RSA and DHE_DSS).

Hopefully that name makes it clear what the routiner's purpose is, and
will encourage people to use it rather than using dissector_add_uint()
with a bogus integer value.

In an other patch I will add some more members to the struct because
the old way of passing them to the function does not scale.

The majority of the fixes are for calls to uat_new(). Instead of
having each caller cast its private data to (void**), we use void*
in the uat_new() API itself. Inside uat_new(), we cast the void*
to void**.
Some dissectors use val64_string arrays, so a VALS64() macro was
added for those, to avoid using VALS(), which is useful only for
value_string arrays.
packet-mq.c was changed because dissect_nt_sid() requires
a char**, not a guint**. All other callers of dissect_nt_sid() use
char*'s (and take the address of it) for their local storage. So,
this was changed to follow the other practices.
A confusion between gint and absolute_time_display_e in packet-time.c
was cleared up.
The ugliest fix is the addition of ip6_guint8_to_str(), for exactly
one caller. The caller uses one type of ip6 address byte array,
while ip6_to_str() expects another. This new function is in place
until the various address implementations can be consolidated.
Add VALS64() to the developer documentation.

DLTS: add cipher version for OpenSSL pre 0.9.8f
OpenSSL pre 0.9.8f uses the TLS version 0x0100 and is not completely
compatible with DTLS 1.0 or 1.2. One difference is that the encrypted
pre master from TLS 1.0 does not have an own length, which is needed by
TLS and DTLS 1.0, this makes decrypting impossible. This patch makes it
possible for the code to distinguish between this OpenSSL version and
real DTLS 1.0, because they are not using the same code any more. This
is needed to fix the snakeoil-dtls test.

I ended up getting rid of most of the explanatory comments since many of them
duplicated what was in the value_string.c file (and were out of sync with the
recent updates I made to those in r48633). Presumably most of the comments
should be in the .h file not the .c file, but there's enough churn ahead that
it's not worth fixing yet.

be done on flows from one address to another; reassembly for protocols
running atop TCP should be done on flows from one TCP endpoint to
another.
We do this by:
adding "reassembly table" as a data structure;
associating hash tables for both in-progress reassemblies and
completed reassemblies with that data structure (currently, not
all reassemblies use the latter; they might keep completed
reassemblies in the first table);
having functions to create and destroy keys in that table;
offering standard routines for doing address-based and
address-and-port-based flow processing, so that dissectors not
needing their own specialized flow processing can just use them.
This fixes some mis-reassemblies of NIS YPSERV YPALL responses (where
the second YPALL response is processed as if it were a continuation of
a previous response between different endpoints, even though said
response is already reassembled), and also allows the DCE RPC-specific
stuff to be moved out of epan/reassembly.c into the DCE RPC dissector.
