b5bcdbaf48 misc: Upgrade to use the vm-memory crate w/ dirty-page-tracking 
As the first step to complete live-migration with tracking dirty-pages
written by the VMM, this commit patches the dependent vm-memory crate to
the upstream version with the dirty-page-tracking capability. Most
changes are due to the updated `GuestMemoryMmap`, `GuestRegionMmap`, and
`MmapRegion` structs which are taking an additional generic type
parameter to specify what 'bitmap backend' is used.

The above changes should be transparent to the rest of the code base,
e.g. all unit/integration tests should pass without additional changes.

e9cc23ea94 virtio-devices: vhost_user: net: Move control queue back 
We thought we could move the control queue to the backend as it was
making some good sense. Unfortunately, doing so was a wrong design
decision as it broke the compatibility with OVS-DPDK backend.

This is why this commit moves the control queue back to the VMM side,
meaning an additional thread is being run for handling the communication
with the guest.

c1be41bfbf net_util: Replace use of rand crate with libc::getrandom() 
The rand crate provides a full cross platform true cryptographic random
number implementation. As such it brings it lots of othe dependencies
and increases our binary size and compile time. This is excessive for
generating a MAC address.

From the cargo tree output:

│   │   │   ├── libc v0.2.86
│   │   │   ├── rand_chacha v0.3.0

4ed0e1a3c8 net_util: Simplify TX/RX queue handling 
The main idea behind this commit is to remove all the complexity
associated with TX/RX handling for virtio-net. By using writev() and
readv() syscalls, we could get rid of intermediate buffers for both
queues.

The complexity regarding the TAP registration has been simplified as
well. The RX queue is only processed when some data are ready to be
read from TAP. The event related to the RX queue getting more
descriptors only serves the purpose to register the TAP file if it's not
already.

With all these simplifications, the code is more readable but more
performant as well. We can see an improvement of 10% for a single
queue device.

0c60fa8268 net_util: tests: Avoid trying to create TAP devices simultaneously 
The unit tests ask the Linux kernel to generate a TAP device name on
demand by passing in a format string. I suspect, but haven't been able
to confirm that there might be a rare race that triggers when creating
lots of devices in a short period of time. This is appearing in our unit
test as the occassional flake of the test_tap_read() which although it
has successfully created the device it fails to set the IP address on it
when looking it back up by it's name.

Since this is the most frequent cause of failures on our CI use a lock
to ensure that multiple TAP devices are not created simultaneously.

Fixes: #2135

929d70bc7f net_util: Only try and enable the TAP device if it not already enabled 
This allows an existing TAP interface to be used without needing
CAP_NET_ADMIN permissions on the Cloud Hypervisor binary as the ioctl to
bring up the interface is avoided.

c31ad72ee9 build: Address issues found by 1.43.0 clippy 
These are mostly due to use of "bare use" statements and unnecessary vector
creation.

1befae872d build: Fixed build errors and warnings on AArch64 
This is a preparing commit to build and test CH on AArch64. All building
issues were fixed, but no functionality was introduced.
For X86, the logic of code was not changed at all.
For ARM, the architecture specific part is still empty. And we applied
some tricks to workaround lint warnings. But such code will be replaced
later by other commits with real functionality.
