Improve stability of ingress drop monitor and reduce long-tail trace generation

This change makes it so that statistics are correctly core-specific.

Interfaces used in bump-in-the-wire configurations were swapped,
possibly during a prior refactor.
Undo this.

…waftr-dev-2021-Q3

Instead of stripping other instances/queues from per-worker configurations,
add the instance and queue id to to worker configurations.

Design based on separate Manager/IO apps design from
ConnectX driver.

Also: set a required reserved bit in txdesc (not sure if it had an effect)

lib.bits uses pairs which is a JIT NYI, leading to split traces
and GC activity due to snapshotting.

when unable to write sriov_numvfs

We observed a deadlock in the syscall migrate_pages when calling it from
the worker processes concurrently to the manager process.

This seems to avoid this by making sure that the manager process binds
to a NUMA node before forking the worker processes.

The relevant call chain here is:
Manager:start() -> cpuset:bind_to_numa_node() ->
numa.bind_to_numa_node() -> S.migrate_pages(...)

This reverts commit 4379d1c.

This reverts commit d4a1083.

Instead we attach instance device/queue_id meta-data to the
worker configs using a setmetatable, and ensure that all
config manipulation based on the worker queue id is performed
within the manager process.

Specifically, this means moving select_instance() from
apps.lwaftr.lwaftr to apps.lwaftr.lwutil and calling it from
program.lwaftr.setup. (I also took the liberty to make this
function pure to avoid future confusion on my end.)

This reverts commit bce8579.

This reverts commit 1cdc635.

This reverts commit dca3004.

This fixes a bug where the YANG parser would not return default values
for leaves which nested in containers left unspecified in the
configuration.

…l-schema

bit munging was broken because of truncation to u8

This allows testing with 1-to-n port setups by e.g. using n 10G ports
in n vlans for load generation connected to
one >10G port used by lwaftr.

…l-schema

NB: extra leaves got stripped by config serialization.
Merge interface configs in lwaftr:new, pass valid-per-schema config to
app but remove all but the respective instance/queue.

Update lwutil.parse_instance to fall back to old behavior
(pre d4a1083).
