A few images were broken with respect to aarch64. We should now
be able to run push-all-images with ARCH=aarch64 as part of the
regular continuous integration builds, and add aarch64 smoke tests
(via user emulation for now) to the regular test suite (future).

Earlier we could not save tcpip.Error objects in structs because upon restore
the constant's address changes in netstack's error translation map and
translating the error would panic because the map is based on the address of the
tcpip.Error instead of the error itself.
Now I made that translations map use the error message as key instead of the
address. Added relevant synchronization mechanisms to protect the structure
and initialize it upon restore.

The loopback interface will never have any neighbouring nodes so
advertising its interest in multicast groups is unnecessary.

Recursive make is difficult to follow and debug. Drop this by using
internal functions, which, while difficult, are easier than trying to
following recursive invokations.
Further simplify the Makefile by collapsing the image bits and removing
the tools/vm directory, which is effectively unused.

Prior to this change tcpdump would fail to create its output file
because the destination directory was owned by root. This would later
cause killall to fail, as tcpdump was not running. Check exit code of
tcpdump/tshark to produce better error messages should this regress.

Avoid action at a distance where both `snifferArgs` and `snifferProg`

Don't propagate arbitrary golang errors up from fusefs because errors
that don't map to an errno result in a sentry panic.

openedMu has lock ordering violations. Most locks go through OpenedFlag(),
which is usually taken after renameMu and opMu. On the other hand, Tlopen takes
openedMu before renameMu and opMu (via safelyRead).
Resolving this violation is simple: just drop openedMu. The opened and
openFlags fields are already protected by opMu in most cases, renameMu (for
write) in one case (via safelyGlobal), and only in doWalk by neither.
This is a bit ugly because opMu is supposed to be a "semantic" lock, but it
works. I'm open to other suggestions.
Note that doWalk has a race condition where a FID may open after the open check
but before actually walking. This race existed before this change as well; it
is not clear if it is problematic.

With the recent changes db36d948fa63ce950d94a5e8e9ebc37956543661, we try
to balance the receive window advertisements between payload lengths vs
segment overhead length. This works fine when segment size are much
higher than the overhead, but not otherwise. In cases where the segment
length is smaller than the segment overhead, we may end up not
advertising zero receive window for long time and end up tail-dropping
segments. This is especially pronounced when application socket reads
are slow or stopped. In this change we do not grow the right edge of
the receive window for smaller segment sizes similar to Linux.
Also, we keep track of the socket buffer usage and let the window grow
if the application is actively reading data.
