afe386bc13 vmm: Only warn on error when setting up SIGWINCH handler
Setting up the SIGWINCH handler requires at least Linux 5.7. However
this functionality is not required for basic PTY operation.

Fixes: #3456

e1c09b66ba vmm: Replace device tree value when restoring DeviceManager
When restoring replace the internal value of the device tree rather than
replacing the Arc<Mutex<DeviceTree>> itself. This is fixes an issue
where the AddressManager has a copy of the the original
Arc<Mutex<DeviceTree>> from when the DeviceManager was created. The
original restore path only replaced the DeviceManager's version of the
Arc<Mutex<DeviceTree>>. Instead replace the contents of the
Arc<Mutex<DeviceTree>> so all users see the updated version.

a29e53e436 vmm: Move KVM clock saving to common Vm::restore() method
Saving the KVM clock and restoring it is key for correct behaviour of
the VM when doing snapshot/restore or live migration. The clock is
restored to the KVM state as part of the Vm::resume() method prior to
that it must be extracted from the state object and stored for later use
by this method. This change simplifies the extraction and storage part
so that it is done in the same way for both snapshot/restore and live
migration.

2f8540da70 vmm: Rename PCI_MMIO_CONFIG_SIZE and move it to arch
The constant `PCI_MMIO_CONFIG_SIZE` defined in `vmm/pci_segment.rs`
describes the MMIO configuation size for each PCI segment. However,
this name conflicts with the `PCI_MMCONFIG_SIZE` defined in `layout.rs`
in the `arch` crate, which describes the memory size of the PCI MMIO
configuration region.

Therefore, this commit renames the `PCI_MMIO_CONFIG_SIZE` to
`PCI_MMIO_CONFIG_SIZE_PER_SEGMENT` and moves this constant from `vmm`
crate to `arch` crate.

07bef815cc aarch64: Introduce struct PciSpaceInfo for FDT
Currently, a tuple containing PCI space start address and PCI space
size is used to pass the PCI space information to the FDT creator.
In order to support the multiple PCI segment for FDT, more information
such as the PCI segment ID should be passed to the FDT creator. If we
still use a tuple to store these information, the code flexibility and
readablity will be harmed.

To address this issue, this commit replaces the tuple containing the
PCI space information to a structure `PciSpaceInfo` and uses a vector
of `PciSpaceInfo` to store PCI space information for each segment, so
that multiple PCI segment information can be passed to the FDT together.

Note that the scope of this commit will only contain the refactor of
original code, the actual multiple PCI segments support will be in
following series, and for now `--platform num_pci_segments` should only
be 1.

In order to avoid the identity map region to conflict with a possible
firmware being placed in the last 4MiB of the 4GiB range, we must set
the address to a chosen location. And it makes the most sense to have

ad8ed80eb1 vmm: use the tty raw mode implementation from libc
I encountered some trouble trying to use a virtio-console hooked up to
a PTY.  Reading from the PTY would produce stuff like this
"\n\nsh-5.1# \n\nsh-5.1# " (where I'm just pressing enter at a shell
prompt), and a terminal would render that like this:

----------------------------------------------------------------

sh-5.1#

       sh-5.1#
----------------------------------------------------------------

This was because we weren't disabling the ICRNL termios iflag, which
turns carriage returns (\r) into line feeds (\n).  Other raw mode
implementations (like QEMU's) set this flag, and don't have this
problem.

Instead of fixing our raw mode implementation to just disable ICRNL,
or copy the flags from QEMU's, though, here I've changed it to use the
raw mode implementation in libc.  It seems to work correctly in my
testing, and means we don't have to worry about what exactly raw mode
looks like under the hood any more.

932c8c9713 vmm: Add CPU affinity support
With the introduction of a new option `affinity` to the `cpus`
parameter, Cloud Hypervisor can now let the user choose the set
of host CPUs where to run each vCPU.

This is useful when trying to achieve CPU pinning, as well as making
sure the VM runs on a specific NUMA node.

a4f5ad6076 option_parser: Fix inner bracket support with list of integers
Give the option parser the ability to handle tuples with inner brackets
containing list of integers. The following example can now be handled
correctly "option=[key@[v1-v2,v3,v4]]" which means the option is
assigned a tuple with a key associated with a list of integers between
the range v1 - v2, as well as v3 and v4.

ad521fd4e4 option_parser: Create generic type Tuple
Creates a new generic type Tuple so that the same implementation of
FromStr trait can be reused for both parsing a list of two integers and
parsing a list of one integer associated with a list of integers.

This anticipates the need for retrieving sublists, which will be needed
when trying to describe the host CPU affinity for every vCPU.

b81d758c41 option_parser: Expect commas instead of colons for lists
The elements of a list should be using commas as the correct delimiter
now that it is supported. Deprecate use of colons as delimiter.
