The LwM2M object instance and resource id may be given in both the
CoAP Uri-Path and the LwM2M TLV header, and in this case the created
uri_path is wrong and resource id lookup will fail.
Change the logic to get object id from CoAP Uri-Path and resource id
from either Uri-Path or LwM2M TLV header.
The return of -1 for negative infinity is glibc specific and
non-portable.

Fixes#18785
The code for dissecting enterprise IEs has been reworked.
Previously, each enterprise was registered by its enterprise-ie in a
dissector-table. The per-enterprise dissector would index into an array
of IEs in order to find the correct IE-dissector.
Using this method has following drawbacks:
- IEs had to be defined in two arrays (value_string and dissector),
possibly causing these two arrays becoming out-of-sync,
- the array only can be indexed if all IE-types are contiguous or gaps
are maintained, which would be wasteful in case of bigger gaps
- individual IEs cannot easily be added outside of the source of this
file
This commit implements a new approach that addresses above drawbacks by:
- defining all IE information together in one array,
- using per-vendor dissector_tables containing per-IE dissector handles,
allowing both for arbitrary ie-types and adding individual
enterprise-IEs separately from external code
This method does a two-level lookup for the IES:
- first looking up a vendor-dissector in the pfcp.enterprise_ies table
- if using the generic-ie-dissector a lookup in the per-vendor table to
find the IE-dissector
A vendor-dissector receives the whole IE including header and has to do
all the work. An IE-dissector receives only the data-part and
a tree + header-fields have already been created.
The code for registering the per-IE tree-types has been modified as
well, because these tree-types are now stored together with the
IE-definitions. (Getting rid of the hardcoded indexes is also a plus.)
The 3GPP example enterprise dissector has been removed, as there are two
other enterprises which can serve as example.

packet-metamako.c: Made heuristic variables available for the user to change via the UI, updated the display strings of the Clause 49 BTF value and the Original FCS status, simplified the heuristic function, added UI options to force trailer dissection (override heuristics), and allow for user specification of whether an FCS is present in the capture, fixed TLV walking bug if the heuristic picks up an invalid TLV length, appends the Info column with a message if the trailer is found, added a generated timestamp field to display the epoch seconds, added total-frame FCS display if total-frame FCS is detected, along with its status.
