This is an attempt to standardize display/handling of checksum fields for all dissectors.
The main target is for dissectors that do validation, but dissectors that just report the
checksum were also included just to make them easier to find in the future.

Some of the ASN.1 dissectors still generate a new_create_dissector_handle from the tool itself, so leave those for now.

We can't use tree_item == NULL to determine which branch of the previous if was
hit, since proto_tree_add_item can return NULL when run without tree, which was
leading to an infinite loop since we were never advancing the offset. Use the
actual locator_type instead.
Introduced by either g3635d7bed70 or gebff85fdbb although neither of them
directly touch this code path. I'm guess that g3635d7bed70 removed an if (tree)
guard in some calling function which would have prevented this, but I haven't
checked. The bug would still have been there before, it just wouldn't have been
hit because it's only present with a NULL tree. Somebody more familiar with the
protocol should probably go over a capture or two and make sure this isn't a
symptom of some other decoding gone awry in the recent changes.

Add macros to set entries of a vec_t, one for use when you have a
pointer to private data, and one for use when you have data in a tvbuff.
The latter wraps the use of tvb_get_ptr(), so that you're not directly
calling it in a dissector.
Move ip_checksum() to epan/in_cksum.c, and add an ip_checksum_tvb() that
wraps the use of tvb_get_ptr().
In the CARP dissector, give the length variable an unsigned type -
there's no benefit to it being signed, and that requires some casts to
be thrown around.
In the DCCP dissector, check only against the coverage length to see if
we have enough data, combine the "should we check the checksum?" check
with the "*can* we check the checksum?" check in a single if, and throw
a dissector assertion if the source network address type isn't IPv4 or
IPv6.
Get rid of inclues of <epan/in_cksum.h> in dissectors that don't use any
of the Internet checksum routines.
In the HIP dissector, make sure we have the data to calculate the
checksum before doing so.

1. Case sensitivity differences between hf_ field name and formatted string.
2. Unnecessary whitespace between hf_ field name and colon in formatted string
There are cases where the hf_ field name doesn't quite match the proto_tree_add_uint_format, but it's close enough that one of them should be "right", I'm just not sure which is, I just know the string in proto_tree_add_uint_format is the one displayed.

The script didn't catch as many as I would have liked, but it's a start.
The most common (ab)use of proto_tree_add_uint_format was for appending strings to CRC/checksum values to note good or bad CRC/checksum.

HIP dissector: PUZZLE and SOLUTION parameters variable size
According to specifications, puzzle and solution parameters carry Random #I and
#J fields that has variable length depending of the Hash function. The fields
are recognized with a fixed value of 8 bytes.
The #I and #J fields should be determined depending of the TLV size.

This patch fixes four issues with the Host Identity Protocol (HIP dissector:
1. The incorrect parsing of the "type 1" locator of HIP.
2. Updates the comments to reflect the approval of RFC 5770.
3. Cosmetic change (uppercase SPI)
4. Change in the checksum dissection
(when the HIP packet is UDP encapsulated 0 checksum is correct).

dissector tables with string keys. (Using _port can confuse people into
