No functionality added in this patch; just a refactor
to distinguish the "observing block device" component of
block watcher from the "filesystem launching" component
of block watcher.

While we don't want participants to be too picky about buffer_count, we
should be able to support cases where a participant must constrain both
the min and max buffer count.  This adds min_buffer_count.

This also moves some constraint checks to make sure we don't have any
constraint checks in the Accumulate* methods, which potentially don't
run if there's only one participant or only one participant specifying
buffer constraints or image constraints.

Tested: CQ, test_sysmem_min_buffer_count added

Also add the new //bundles/buildbot:bringup group.  The new model is
that for each product whose build is tested by bots, there should be
a //bundles/buildbot:$product group.  The bot configs will use that,
so `fx set PRODUCT.BOARD --with-base //bundles/buildbot:PRODUCT` will
approximate in a local build what the bots will do.

Bug: INTK-1015 #comment Define //bundles/buildbot:{bringup,core} groups

The old - names were only ever used because of limitations of the
old Zircon build system, which is no longer an issue.  The target
name in banjo_library() must always match the library name.  For
public Banjo libraries, the directory name matches that name too.

LowEnergyConnectionManager now responds to local identity information
requests during the feature exchange and key distribution phases of SMP
pairing.

Bug: BT-243 #done
Test: 1. Run bt-pairing-tool, bt-le-battery-peripheral, and
         bt-le-peripheral -c -n <NAME> on Fuchsia. This will put Fuchsia
	 into LE peripheral mode with one GATT service that requires
	 security.
      2. Connect to Fuchsia from iOS using the nRF Connect app. This
         should trigger LE pairing. Respond to the authentication challenge
	 using bt-pairing-tool (local passkey entry on ToT). The battery
	 service characteristic should be readable and notifiable
	 without any errors.
      3. Pipe the output of bt-snoop-cli to Wireshark and confirm that:
         a. Fuchsia configured advertising using a random address.
	 b. Local IRK and identity address were distributed over SMP.
	 Check that the IRK matches what has been persisted in the
	 stash. Check that the identity address matches the address of
	 the active adapter (confirm via bt-cli).
      4. Reboot Fuchsia, repeat step #1. Connect again using nRF
         Connect. The battery service should be accessible without
	 additional pairing errors.
      5. Check the snoop logs to confirm that Fuchsia used a different
         RPA when advertising.

This CL changes the behavior of the media player when the audio
renderer holds on to packets too long, which generally happens due to
scheduling issues. Because the player has allocated a limited amount
of space for transferring packets between itself and the renderer,
that space can be exhausted if the renderer doesn't retire packets
quickly enough.

The fix is to drop packets instead of panicking. There are a few
paths that had to be fixed to enable this. Sometimes the memory
allocation failures occur in a callback from the audio decoder.
Sometimes audio has to be interleaved after the decoder, and the
allocation failure is detected there. Sometimes (when no decoder
is needed) audio needs to be copied from system memory into vmo
memory, and the failure happens prior to the copy.

Two tests have been added to replicate these failure modes. Those
tests produced panics before the fixes were introduced.

TEST: new CQ tests

To make fx run -N even more friendly, I added "&&" (continue with
the next command if the first command succeeds) and "\" (continue
command on the next line) so users can simply copy and paste the
helpful commands in a single copy-and-paste action.

I find I have to re-enable tun/tap after each reboot of my Linux
machine. Of course, I don't remember until I try the "fx run" command,
but "fx run" helpfully prints the suggested commands to do that:

  To use qemu with networking on Linux, configure tun/tap:
  sudo ip tuntap add dev qemu mode tap user richkadel
  sudo ifconfig qemu up

Without thinking about it, it might seem like you should be able to
copy and paste both lines, but this fails because the sudo in the first
line tries to use the second line as the password.

The change simplifies running the commands, and may be less confusing.
