[PATCH v5 0/5] Re-implement prserv on top of asyncrpc

["Scott Murray" <scott.murray@konsulko.com>]

These changes replace the old XML-based RPC system in prserv with the
new asyncrpc implementation originally used by hashserv, and add a
read-only mode to match the hash equivalency server's support.

Changes from v4:
  * Patch 2 updated to conditionalize all_tasks/current_task usage
    from asyncio vs asyncio.Task based on Python version.  This fixes
    running against Python 3.9 where they were finally removed from
    asyncio.Task.

Changes from v3:
  * Scott Murray taking over upstreaming effort from Paul Barker.

  * Dropped patches which are currently applied to master-next, this
    series should be applied on top of the current master-next branch.

  * Patches 2-4 updated by Scott Murray to rebase on top of 3983643
    ("bitbake: asyncrpc: Catch early SIGTERM").

  * Read-only PR server support patch added to stack to get it into
    the review process.
