Add an FT_CHAR type, which is like FT_UINT8 except that the value is
displayed as a C-style character constant.
Allow use of C-style character constants in filter expressions; they can
be used in comparisons with all integral types, and in "contains"

Use that type for some fields that appear (based on the way they're
displayed, or on the use of C-style character constants in their
value_string tables) to be 1-byte characters rather than 8-bit numbers.

There's no guarantee that the identity is a string whose first character
is a prefix indicating the type of identity; only display it as a prefix
if it's one of the known types. We really may need some other mechanism
to determine how to parse the identity, perhaps based on what the
protocol layers below it are.
Put back the display of the full string in one case where that was
inadvertently removed.

There was an implicit dependency between the block size in the cipher
suites table and the size expected by Libgcrypt. Just remove the block
size from the table and rely on the value from Libgcrypt to avoid the
risk of mismatching values (which could lead to a buffer overflow).
While at it, remove the size of the key ("bits") and the size of key
material ("eff_bits") too. Move the key material sizes for export
ciphers away from the table and use byte quantities instead of bits.
Additionally, this fixes an issue where 8 bytes of uninitialized stack
memory is written to the SSL debug log for stream ciphers like RC4.
The size of the Write Key is also corrected for export ciphers, now it
prints the actual (restricted) number of bytes that are used.

Fixes a buffer overrun (read) by 12 bytes for any AES-CCM and AES-GCM
cipher suite because the "block size" is set to 4 bytes while the
reported block size for AES is 16 bytes (128 bit). (The four bytes are
the "salt" part of the nonce that is extracted from the "client/server

Use new heuristics based on the EAP Code field to determine whether a
field originates from the client or server. This is more reliable than
using "pinfo->match_uint" for two reasons: (1) the heuristics dissector
does not set "match_uint" (resulting in an arbitrary match on the
previous value) and (2) with EAP over EAPOL, there is no matching port
number (resulting in two conversations with different addresses and port
number zero).
To fix TLS decryption, make sure to create a single conversation for
both direction and allow the port type to be PT_NONE (to avoid reporting
all packets as originating from the server).
