f4fcf5d6eb dm: virtio: remove hv_caps from virtio_ops
currently, each virtio device has their own virtio_ops implementation.
Take virtio-blk for example:

static struct virtio_ops virtio_blk_ops = {
        "virtio_blk",
        1,
        sizeof(struct virtio_blk_config),
        virtio_blk_reset,
        virtio_blk_notify,
        virtio_blk_cfgread,
        virtio_blk_cfgwrite,
        NULL,
        NULL,
        VIRTIO_BLK_S_HOSTCAPS,
};

If start DM with two virtio-blk, this global variable will be
assigined to two virtio-blk instances. Changing hv_caps for one
instance will affect others. But different instances may need
different capabilities.

To support this requirement, we suggest to move hv_caps to
virtio_base structure, and each instance can return their own
capabilities.

d63b9002dd dm: code clean up
Following functions have never been used anywhere.
Let's remove them.

fbsdrun_muxed()
fbsdrun_vmexit_on_hlt()
fbsdrun_vmexit_on_pause()
fbsdrun_disable_x2apic()

Remove weird prefix "fbsdrun" from following functions' name.

fbsdrun_virtio_msix()  -->  virtio_uses_msix()
fbsdrun_start_thread() -->  start_thread()

a3316241d4 dm: virtio-console: Fix the bug that ports cannot work
If multiple ports are defined in the command line, is_console is
not set to a correct value for non-console ports when the definition
of this non-console port is following the definition of a console port.
For example in below definition, the second port is configured as
console port which is not correct:

-s 5,virtio-console,@pty:pty_port,file:file_port=/home/root/test1

097aee76bf DM: release mevent when doing virtual device deinit
When doing warm reboot, the mevent module will not be deinitialized.
We need to delete all mevent registered while deinit virutal device.

c6bf67543c DM: mevent_add/del refine for Linux
Unlike kqueue/kevent of BSD, the epoll of Linux could be
add/del by using different API on the fly.

This patch drops the notify used by mevent_add/del and
call epoll_ctl to add/delete target fd. Only keeps
global_head to track mevent added and makes the code
logic in mevent_dispatch() a littel bit simpler.

Another thing is related with epoll_ctl. If the target
fd is regular fd which doesn't support epoll, epoll_ctl
will return -1. When DM is start by systemd, the STDIO
is not mapped to terminal, epoll_ctl on STDIO could
return -1. Which block UOS boot. We only call mevent_add
after confirm STDIO is mapped to terminal.
