couple of problems when reading the PROTOS SNMP captures. Check for
integer overflows in dissect_snmp_pdu and asn1_null_decode.

Ethernet frames, one for encapsulated frames that include an FCS and one
for encapsulated frames that don't include an FCS. Use the appropriate
versions.
In the ISL dissector, do the same sort of processing we do in the
Ethernet dissector to figure out whether the frame has a trailer or not
and whether it has an FCS or not.

The compression option isn't just the compression protocol, it can
include options for the protocol, so name the ett_ variable for its tree
appropriately.

1. Add Preferences:
a. To allow specification of a hint as to TDS protocol being decoded
(Unspecified/TDS4/TDS5/TDS7/TDS8); Default: 'unspecified'
The 'hint' is used only when needed to do a correct decode.
If the protocol is unspecified, the decode is as previous.
b. To allow specification of 'ranges' of TCP ports to be treated as
'TDS tcp ports'; i.e. if the source or destination port of a tcp
connection matches a specified range, then the connection should be
considered to be TDS.
c. To allow specification of a hint as to whether TDS being decoded is
'little-endian' or 'big-endian'. Default: 'little-endian'.
A hint is just that; E.G. if TDS7+ packets are encountered the decode
is always 'little-endian'.
2, Register tcp MS SQL default ports (1433, 2433) as TDS ports
('dissector_add'). This also enables TDS as a choice for 'decode as'.
3. 'netlib_check_login_pkt' changed to check 'TDS tcp port' range(s) as
entered in preferences;
4. Change 'dissect_tds_query_packet' to handle TDS4 ascii in addition to
TDS7/8 UCS-16.
5. Change 'dissect_tds_rpc' to:
a. handle TDS4 ascii RPC in addition to TDS7/8 UCS-16 RPC;
b. handle Microsoft 'encoded' rpc_name;
c. fix memory leak (not freeing memory obtained using
'tvb_fake_unicode');
6. Change 'dissect_tds_response' to:
a. handle tds4 tokens 'tds_col_name' and 'tds_col_info';
b. dissect tokens 'tds_doneinproc' and tds 'doneproc' similarly to
'tds_done'
c. reclaim memory allocated for 'tds_col' structures when finished
processing response
(Additional memory was being allocated each time a
tokenized tds5 response was processed)
7. New function 'dissect_tds_col_info_token' (similar to
'read_results_tds5') associated with handling TDS4 responses.
8. New functions 'dissect_tds_query5_packet', 'dissect_tds5_lang_token'
9. Rework TDS token size calculation; Some TDS tokens have a length field
of other than 2 bytes. (e.g.: the length field
for TDS_LANG_TOKEN is 4 bytes)
10. Update token definitions and usages;
a. Update based upon info from current version of FreeTDS 'tds.h'
as well as info from Sybase TDS5 document;
example: TDS_124_TOKEN renamed to TDS_PROCID_TOKEN
b. TDS_124_TOKEN [TDS_PROCID] was incorrectly not considered
a 'fixed-size' token in function 'tds_is_fixed_token'
