Containers without recognized file systems already won't autosize, but now
you can't attach a container which is larger than the current drive type
presuming there is useful data beyond the size of the current drive type.
Add optional enabling of broadcast address to hash based filter model.
LANCE based devices which use its AUTODIN II based hash generally
match the broadcast address independent of the contents of the
multicast hash.
This change to XQ mostly undoes the prior change to pdp11_xq and
brings the functionality into sim_ether so that it is generally available
for future ethernet devices.
Some dependent packages on some platforms may also define HAVE_DLOPEN
and that definition may have different syntax or semantics. This change
avoids the potential symbol conflict.

For some strange reason, Ubuntu 21.10 delivers various libraries as
either direct link libraries (".a") or shared objects (".so") where
historically essentially everything was shared objects..
At one point in the distant past, there was an unremembered
reason to prefer __libc_longjmp if it was available. It is no
longer needed, and has been removed from glibc in the most recent
versions.
Fixes#1088.
- removed a somwhat unlikely but possible division-by-zero
- in case the initial throttling calibration measures a slower cps rate than
the desired cps rate, check whether the measured rate is well below the
measured peak rate. If so, distrust the measured rate and instead use
half the peak rate as measured cps rate.
Otherwise (so measured cps is in the same ballpark as measured peak rate)
disable throttling

The modem and host interface TX services should both be called from
the RTC device, but when the host interface was implemented the call
was not added.
This adds a new flag to the host interface UDP packages to indicate
the ready bit of the sender. The flag comes along all packets, but an
empty packet can be sent to change the ready status without
transmitting data.
The 1822 IMP-host interface carefully handshakes every bit
transferred. Thus the DMC facility can read messages piecewise. The
IMP uses this to read a 32-bit leader first, and process the rest or
the message in another round.
The IMP expects the 1822 end of message bit not to be set until after
the entire message has been read.
The host interface uses the UDP packet format from the modem
interface, with an additional flags word. Ensure the flags are
not included in the word count.
This is a trivial correction since if dependencies are missing at build
time what is missing is and how to fix it is properly described in
build time messages.

This commit fixes an issue that caused floppy diagnostics to fail if
the floppy drive unit was not attached. The 3B2 floppy controller has
a "force interrupt" command that should run whether or not the floppy
unit is attached to an image.
Historically on *nix platforms ifconfig was used to find the host system's
interface MAC address. This isn't always available on all systems since
it's being replaced by the ip command. We now only invoke commands
that exist.
- This change introduces a full refactor of the interrupt subsystem
for the system board (SBD) and the I/O bus (CIO). Interrupt decode
should now be significantly faster, and not require an expensive
calculation on every step.
- The TIMER device has been split into Rev 2 and Rev 3
implementations.
- The optional 3B2/400 Debug Monitor ROMs can now be booted by passing
the "DEMON" argument to the 3B2/400 simulator BOOT command. Any
of the following will cause the Debug Monitor ROM to be booted
instead of the standard 3B2/400 ROM:
sim> BOOT DEMON
sim> BOOT CPU DEMON
sim> BOOT DEMON CPU
