ba1e89139a pci: aml: support up to 256 PCI segments
Originally the AML only accepted one hex number for PCI segment
numbering. Change it to accept two numbers. That makes it possible to
add up to 256 PCI segments.

21d40d7489 main: reset tty if starting the VM fails
When I refactored this to centralise resetting the tty into
DeviceManager::drop, I tested that the tty was reset if an error
happened on the vmm thread, but not on the main thread.  It turns out
that if an error happened on the main thread, the process would just
exit, so drop handlers on other threads wouldn't get run.

To fix this, I've changed start_vmm() to write to the VMM's exit
eventfd and then join the thread if an error happens after the vmm
thread is started.

c90a0ffff6 vmm: reset to the original termios
Previously, we used two different functions for configuring ttys.
vmm_sys_util::terminal::Terminal::set_raw_mode() was used to configure
stdio ttys, and cfmakeraw() was used to configure ptys created by
cloud-hypervisor.  When I centralized the stdio tty cleanup, I also
switched to using cfmakeraw() everywhere, to avoid duplication.

cfmakeraw sets the OPOST flag, but when we later reset the ttys, we
used vmm_sys_util::terminal::Terminal::set_canon_mode(), which does
not unset this flag.  This meant that the terminal was getting mostly,
but not fully, reset.

To fix this without depending on the implementation of cfmakeraw(),
let's just store the original termios for stdio terminals, and restore
them to exactly the state we found them in when cloud-hypervisor exits.

b6feae0ace vmm: only touch the tty flags if it's being used
When neither serial nor console are connected to the tty,
cloud-hypervisor shouldn't touch the tty at all.  One way in which
this is annoying is that if I am running cloud-hypervisor without it
using my terminal, I expect to be able to suspend it with ^Z like any
other process, but that doesn't work if it's put the terminal into raw
mode.

Instead of putting the tty into raw mode when a VM is created or
restored, do it when a serial or console device is created.  Since we
now know it can't be put into raw mode until the Vm object is created,
we can move setting it back to canon mode into the drop handler for
that object, which should always be run in normal operation.  We still
also put the tty into canon mode in the SIGTERM / SIGINT handler, but
check whether the tty was actually used, rather than whether stdin is
a tty.  This requires passing on_tty around as an atomic boolean.

I explored more of an abstraction over the tty — having an object that
encapsulated stdout and put the tty into raw mode when initialized and
into canon mode when dropped — but it wasn't practical, mostly due to
the special requirements of the signal handler.  I also investigated
whether the SIGWINCH listener process could be used here, which I
think would have worked but I'm hesitant to involve it in serial
handling as well as conosle handling.

There's no longer a check for whether the file descriptor is a tty
before setting it into canon mode — it's redundant, because if it's
not a tty it just won't respond to the ioctl.

Tested by shutting down through the API, SIGTERM, and an error
injected after setting raw mode.
