Previously it was not always possible to prepend the header.
It was not possible if the application neglected to reserve the space
for headers. This is bad because it forces a buffer segment allocation
even if the buffer had enough room for the headers. E.g. a payload of 10
bytes in a netbuf of 30 bytes would have been segmented.
We now explicitly reject the buffer if it does not have the headroom.
This allows us to do a nice thing; simplify L2CAP segmentation.
We convert the SDU from the application into a PDU payload, by
prepending the SDU header, i.e. the SDU length in the original buffer.
This PDU payload is ready to be chunked into PDUs without having to keep
track of where in the SDU we are. This has the effect of removing a
bunch of logic in the segmentation machine.

On newer GCC version warnings were emitted because of a `memcpy`. The
size parameter was larger than the source's size because it was using
the size of the destination, which was a `bt_uuid_128` when the source
is a `bt_uuid_16`.
Fix the issue by creating a new variable for CCC UUID in both the
central and peripheral code. The variable need to be static because the
discover parameters must remain valid until the start of the discover
attribute callback.

Signed-off-by: Anders Storrø <anders.storro@nordicsemi.no>
Refactors proxy advertising implementation to allow fair sharing of
advertising resources between all subnets.
In the new implementation, each subnet is agnostic to any other subnet
that might have active proxy advertisement work. When proxy
advertisement is triggered, the implementation will first check how
many subnets that has active work. If there are more than one active
subnet, a maximum timeslot will be calculated to ensure that all active
subnets get access to the medium. The implementation will then poll
the next eligible subnet for a proxy advertising request. If the
duration of this request exceeds the maximum timeslot, the duration
for the next advertisement will be set to the maximum value.
If a proxy advertisement for a subnet is interrupted by other
advertising activity, the implementation will now ensure that the
interrupted proxy adv continues from the point where it was
interrupted so that the subnet gets to utilize the entire allocated
timeslot.
This PR also alters the priv_proxy_net_id_multi Bsim test to align
with the refactored proxy advertising scheme.

The section 3.7.3.1 of the mesh specification recommends to delay
a message publication in certain cases:
- at power-up or upon state change for a time between 20 to 500 ms
- for periodic publications for a time between 20 to 50 ms
This change implements this recommendation by adding the
`CONFIG_BT_MESH_DELAYABLE_PUBLICATION` Kconfig option which enables
the randomization code and by adding the `bt_mesh_model_pub.delayable`
bit field which allows each model decide whether the publications
should be delayed for this model or not.

Why?
- metadata is easier to manage as an array + index
- less error-prone -> less memory-management bugs
- we can. because of the previous refactor
- PDU allocations are more predictable
- ATT buffer size can be optimized by app
- isolates ATT from the rest of the ACL users
- decouples ATT PDU size from e.g. SMP w/ LESC
Drawbacks:
- higher memory usage
- kconfig change
The higher memory use is only temporary, as this will be followed-up
with more refactors that should bring it back down.

This removes the fixed size bt_bap_base, which provides
2 improvements:
1) The RAM usage of the broadcast sink has been reduced.
For the Broadcast Sink sample it is a reduction of 120
octets, but with much better scaling for supporting
more or larger BASEs.
2) The functions to parse BASEs now support arbitrary sized
BASEs, where they were previously restricted by our
local Kconfig options. This allow us to parse any BASE
from a remote device, without encounting memory issues.
We are still memory restricted on the devices we
actually want to sync to.
