Move from synchronous flushing of io and ctrl events from transports to
applications to an async model via a new session_input input node that
runs in interrupt mode. Events are coalesced per application worker.
On the one hand, this helps by minimizing message queue locking churn.
And on the other, it opens the possibility for further optimizations of
event message generation, obviates need for rx rescheduling rpcs and is
a first step towards a fully async data/io rx path.

In case of UDP length errors in udp_local node, these errors are
being lost and incomplete header may be advanced by wrong offset.
Fix it with only full packets processing and explicit error set
otherwise. Also, optimize two buffer loop perfomance into fast
path with both buffers are ok and slow path with one or none.

Not ideal. The sparse vector used to map ports to next nodes assumes
only a few ports are ever used. When udp transport is enabled this does
not hold and, to make matters worse, ports are consumed in a random
order.
This can lead to a lot of slow updates to internal data structures
which in turn can slow udp connection allocations until all ports are
eventually consumed.
Consequently, reallocate sparse vector, preallocate all ports and have
them point to UDP_NO_NODE_SET. We could consider switching the sparse
vector to a preallocated vector but that would increase memory
consumption for vpp deployments that do not rely on host stack.
For reference, populating one of the v4 or v6 sparse vectors in reverse
order takes about 9.8s on a skylake cpu.

Encode entropy value in UDP source port when requested per RFC 7510.
CLI already has "src-port-is-entropy", use zero UDP source port in API
to avoid breaking changes, since zero port is not something to be used
in wild.
Also, mark UDP encapsualtion API as mp-safe as already done for CLI.

When computing the inner packet checksum, the code wrongly
assumes that the IP version of the inner packet is the
same of the outer one. On the contrary, it is perfectly
possible to encapsulate v6 packets into v4 and viceversa,
so we need to check the IP format of the inner header before
calling vnet_calc_checksums_inline.

We do not want to encap headers containing wrong checksums.
Additionnally, this clears the checksums offlads flags, which
was something missing since the outer headers checksums were
calculated during the encap. Hence, those should not be
recalculated afterwards.

Type: refactor
This patch refactors the offload flags in vlib_buffer_t.
There are two main reasons behind this refactoring.
First, offload flags are insufficient to represent outer
and inner headers offloads. Second, room for these flags
in first cacheline of vlib_buffer_t is also limited.
This patch introduces a generic offload flag in first
cacheline. And detailed offload flags in 2nd cacheline
of the structure for performance optimization.
