612621bb46 vmm: Improve "cloud-hypervisor --help" view format 
Rust documentation comments follows 80 char per line. But some of
these help options doesn't have space in between. Longlines of
text is starting from beginning of the next line instead of
proper format.

Before fix:

Options:
  --cpus            boot=<boot_vcpus>,max=<max_vcpus>,topology=<threads_per_core>:<cores_per_die>:<dies_per_package>:<packages>,kvm_hyperv=on|off,max_phys_bits=<maximum_number_of_physical_bits>,affinity=<list_of_vcpus_with_their_associated_cpuset>,features=<list_of_features_to_enable>

After fix:

Options:
  --cpus            boot=<boot_vcpus>, max=<max_vcpus>,
                    topology=<threads_per_core>:<cores_per_die>:<dies_per_package>:<packages>,
                    kvm_hyperv=on|off,
                    max_phys_bits=<maximum_number_of_physical_bits>,
                    affinity=<list_of_vcpus_with_their_associated_cpuset>,
                    features=<list_of_features_to_enable>

1976157761 main: Fix error propagation if starting the VM fails 
Commit 21d40d7 ("main: reset tty if starting the VM fails") changed
start_vmm() to join the vmm thread if an error happens after the vmm
thread is started. The implementation put all the error-prone code that
is run after the vmm is started in a closure, to be able to always join
the vmm thread, regardless of any error happening. However, it missed
propagating the error that might happen inside the closure back to the
main function, after joining the vmm thread.

For some cmd line options, the above issue inhibits proper error
reporting when starting a VM with invalid commands, as many parameters
are parsed after the vmm is started, thus if such parsing fails, no
error will be reported back to the user.

See: #5435

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.

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.

d17d70fae1 vmm: Update for new acpi_tables version 
In particular the Std::write() API requires that the value implements
AsBytes and copies the slice representation into the table data. This
avoids unaligned writes which can cause a panic with the updated
toolchain.

71d1296d09 vmm: Implemented zerocopy::AsBytes for SDT structures 
For structures that are used in SDT ACPI tables it is necessary for them
to implement this trait for the newly safe Std::write() API.
