eca75dcfc9 vfio: align memory region size and address to PAGE_SIZE 
In current implementation, memory region used in vfio is assumed to
align to 4k which may cause error when the PAGE_SIZE is not 4k, like on
Arm, it can be 16k and 64k.

Remove this assumption and align memory resource used by vfio to
PAGE_SIZE then vfio can run on host with 64k PAGE_SIZE.

Fixes: #5292

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.
