Modbus object support for CIP dissector
Support for the Modbus object within the CIP dissector. Essentially wraps the Modbus protocol within a CIP object.
Also included update to Modbus error code per

Don't set mr_mult_req_info->num_services until we're sure we've
initialized the full structure for that service. Otherwise if we
happen to throw an exception before initializing the whole
structure, we'll core someplace (like dissect_cip_generic_service_rsp())
which expects all num_services entries to be fully initialized.

1. If there's no character encoding (ENC_ASCII, ...) specified
then use ENC_ASCII.
2. For all but FT_UINT_STRING, always use ENC_NA
(replacing any existing True/1/FALSE/0
/ENC_BIG_ENDIAN/ENC_LITTLE_ENDIAN).

From me:
packet-cipmotion.c:
FT_BOOLEAN fields with bitmasks need a bit-fieldwidth in the hf[] entry 'display' field;
Define attribute_size as guint32 since it has to store guint8*guint16;
Use ENC_NA as encoding arg in proto_tree_add_item() for FT_BYTES field types;
Remove trailing whitespace from lines;
Other minor cleanup and reformatting.
packet-enip.c:
Use ENC_NA as encoding arg in proto_tree_add_item() for FT_BYTES field types;
svn path=/trunk/; revision=39396
Specifically: Replace FALSE|0 and TRUE|1 by ENC_BIG_ENDIAN|ENC_LITTLE_ENDIAN as
the encoding parameter for proto_tree_add_item() calls which directly reference
an item in hf[] which has a type of:
FT_UINT8
FT_UINT16
FT_UINT24
FT_UINT32
FT_UINT64
FT_INT8
FT_INT16
FT_INT24
FT_INT32
FT_INT64
FT_FLOAT
FT_DOUBLE
svn path=/trunk/; revision=39288
FT_NONE
FT_BYTES
FT_IPV6
FT_IPXNET
FT_OID
Note: Encoding field set to ENC_NA only if the field was previously TRUE|FALSE|ENC_LITTLE_ENDIAN|ENC_BIG_ENDIAN

Added support for the following services of the Connection Manager object:
LargeForwardOpen
GetConnectionOwner
Added support for the following services of the Connection Configuration
Object:
GetAttributeAll
SetAttributeAll
From me:
Replace tabs with spaces; adjust modelines for 8-space tabs instead of 3.

keys to have _uint in their names, to match the routines that handle
dissector tables with string keys. (Using _port can confuse people into
thinking they're intended solely for use with TCP/UDP/etc. ports when,
in fact, they work better for things such as Ethernet types, where the
binding of particular values to particular protocols are a lot
stronger.)

Function dissect_epath() expects path_length in bytes, but the value from the
packet is in words, so there's lots of *2 and /2 in those parts of the code.
In this invocation dissect_epath( tvbIOI, pi, 0, preq_info->IOILen, TRUE );
preq_info->IOILen is in words.
In six places proto_tree_add_item is used with tvb NULL and size 0 to add an
FT_UINT8/16/32 item. I think it should be replaced with proto_tree_add_uint().

This patch correctes serveral minor things.
1. Adds decoding of generic services to classes that have a separate dissect
function.
2. Adds new error codes.
3. Adds new CIP objects.
4. Extends the VendorID list.

(1) Trailing/leading spaces are removed from 'name's/'blurb's
(2) Duplicate 'blurb's are replaced with NULL
(3) Empty ("") 'blurb's are replaced with NULL
(4) BASE_NONE, NULL, 0x0 are used for 'display', 'strings' and 'bitmask' fields
for FT_NONE, FT_BYTES, FT_IPv4, FT_IPv6, FT_ABSOLUTE_TIME, FT_RELATIVE_TIME,
FT_PROTOCOL, FT_STRING and FT_STRINGZ field types
(5) Only allow non-zero value for 'display' if 'bitmask' is non-zero

- if offset is 0, tvb_length is the same as tvb_length_remaining, just faster.
Replace
- col_append_fstr() with faster col_append_str()
- col_add_str() with col_set_str()
when it's safe

-use g_snprintf instead of sprintf and snprintf
-use g_strdup_printf where appropriate
-remove #include "snprintf.h" (as only g_snprintf should be used)
-replace some more alloc/realloc/calloc/free with their glib pendants
