When the string "str" is empty, "str+1" is invalid. This function can be
called from functions using SET_ELEM_VARS in packet-gsm_a_common.c which
appear to check the length first, but packet-etsi_card_app_toolkit.c and
packet-camel.c do not. Err on the safe side and do not add the item.

3GPP 24.008 is not very explicit regarding the encoding, but after
rereading 3GPP 23.003 and 3GPP 29.272, it is most likely the E.164
number in TBCD encoding (so without TON/NPI byte).

When a mandatory information element is missing, try to report an expert info,
instead of throwing a fatal malformed exception (or of reporting nothing at all).
According to TS 24.007 11.2.3, a mandatory i.e. may be part of the imperative part
of the message, so that expert info should be at PI_ERROR level

Have all dissector tables have a "supports Decode As" flag, which
defaults to FALSE, and which is set to TRUE if a register_decode_as()
refers to it.
When adding a dissector to a dissector table with a given key, only add
it for Decode As if the dissector table supports it.
For non-FT_STRING dissector tables, always check for multiple entries
for the same protocol with different dissectors, and report an error if
we found them.
This means there's no need for the creator of a dissector table to
specify whether duplicates of that sort should be allowed - we always do
the check when registering something for "Decode As" (in a non-FT_STRING
dissector table), and just don't bother registering anything for "Decode
As" if the dissector table doesn't support "Decode As", so there's no
check done for those dissector tables.

This saves many dissectors the need to find the data dissector and store a handle to it.
There were also some that were finding it, but not using it.
For others this was the only reason for their handoff function, so it could be eliminated.

Started by grepping call_dissector_with_data, call_dissector_only and call_dissector and traced the handles passed into them to a find_dissector within the dissector. Then replaced find_dissector with find_dissector_add_dependency and added the protocol id from the dissector.
"data" dissector was not considered to be a dependency.

The target here is the Decode As dialog where protocols have multiple registrations into a dissector table and that shows up as multiple entries in the Decode As dialog list with the same name so users are unsure which "dissector" they are choosing.
The "default" behavior (done in this commit) is to not allow duplicates for a dissector table, whether its part of Decode As or not. It's just ENFORCED for Decode As.

Add a CF_FUNC macro to match VALS, TFS, etc. This should help us to avoid

warning: ISO C forbids initialization between function pointer and 'void *' [-Wpedantic]
We could start adding DIAG_OFF+DIAG_ON everywhere but this seems to be
more consistent with the other macros in proto.h. Update each instance
of BASE_CUSTOM to use CF_FUNC.
