Verify that skipping used IDs works for:
- PFCP UP-SEID
- GTP local TEID
- chain_id for nft rulesets -- so far expected to fail,
fix follows in I139b46de0bd15185a7a06109d55f7c759755ec81.

To avoid actions that require cap_net_admin permissions on build
servers, add this option to "dry run" all kernel GTP actions. Same will
be added for netfilter rules.
On startup, osmo-upf opens sockets to GTP kernel module / NFT ctx.
However, on build servers, this would require giving cap_net_admin
permissions just to run the VTY tests.

An all new TLV parser supporting:
- Any size of T and L (determined by callback function),
- "Grouped IEs", so that an IE payload is a nested IE structure,
- optional/mandatory/multi-occurence IEs,
- decoding unordered tags (or enforcing strict order).
Will be used for PFCP message decoding and encoding, a T16L16V protocol
which requires above features.
Upcoming patches add
- translating PDUs to plain C structs and vice versa
- TLV generator to reduce repetition a in protocol definition
- TLIV capability
Previously, the way we deal with TLVs causes a lot of code
re-implementation: the TL decoding is taken care of by the API, but for
encoding, we essentially re-implement each protocol and each encoded
message in the individual programs. This API is an improvement in that
we only once implement the TL coding (or just use osmo_t8l8v_cfg /
osmo_t16l16v_cfg), get symmetric de- and encoding of the TL, and only
need to deal with the value part of each IE.
The common pattern of
- store TL preliminarily,
- write V data and
- update L after V is complete
is conveniently done by osmo_gtlv_put_update_tl().
