[PATCH v3 00/25] RFC: Read-only dynamic update implementation

[David Gibson <david@gibson.dropbear.id.au>]

Here's a new draft of dynamic updates.  This now can successfully
update rules, though I've not tested it very extensively.  Essentially
this is just barely enough to work, it still could do with rather a
lot of polish.

Patches 1..12/22 are preliminary reworks that make moderate sense even
without pesto - feel free to apply if you're happy with them.

Changes in v3:
 * Removed already applied ASSERT() rename
 * Renamed serialisation functions
 * Incorporated Stefano's extensions, reworked and fixed
 * Several additional cleanups / preliminary reworks
Changes in v2:
 * Removed already applied cleanups
 * Reworked assert() patch to handle -DNDEBUG properly
 * Numerous extra patches:
   * Factored out serialisation helpers and use them for migration as
     well
   * Reworked to allow ip.[ch] and inany.[ch] to be shared with pesto
   * Reworks to share some forwarding rule datatypes with pesto
   * Implemented sending pif names and current ruleset to pesto

David Gibson (22):
  conf: runas can be const
  vhost_user: Fix assorted minor cppcheck warnings
  serialise: Split functions user for serialisation from util.c
  serialise: Add helpers for serialising unsigned integers
  fwd: Move selecting correct scan bitmap into fwd_sync_one()
  fwd: Look up rule index in fwd_sync_one()
  fwd: Store forwarding tables indexed by (origin) pif
  fwd: Allow FWD_DUAL_STACK_ANY flag to be passed directly to
    fwd_rule_add()
  fwd, conf: Expose ephemeral ports as bitmap rather than function
  conf: Don't bother complaining about overlapping excluded ranges
  conf: Move check for mapping port 0 to caller
  conf: Move check for disabled interfaces earlier
  pesto: Introduce stub configuration interface and tool
  pesto: Add command line option parsing and debug messages
  pesto: Expose list of pifs to pesto
  ip: Prepare ip.[ch] for sharing with pesto tool
  inany: Prepare inany.[ch] for sharing with pesto tool
  fwd: Split forwading rule specification from its implementation state
  ip: Define a bound for the string returned by ipproto_name()
  fwd_rule: Move forwarding rule text formatting to common code
  pesto: Read current ruleset from passt/pasta and display it
  conf, fwd: Allow switching to new rules received from pesto

Stefano Brivio (3):
  conf: Move port parsing functions to own file, ports.c
  conf, fwd, ports, util: Move things around for pesto
  pesto, conf: Parse, send and receive new rules
