This includes fixes for two issues pointed out by FreeBSD's Coverity,
as well as a -Wcast-qual complaint.
While we're here, ignore build artifacts as well upon import.
Intel Control-flow Enforcement Technology (CET) provides new
instructions `endbr32/64` for the indirect branch control.
They are NOPs on i686 and new targets. We need to check for that
in case it crashes on older targets.

Added support for application management interface. There are two types of commands supported:
1. Firmware IOCTLs: These ioctls are meant for firmware
consumption. Driver acts as a transport for these.
2. Driver only IOCTLs: These ioctls are meant for driver
consumption. Driver will serve these ioctls without sending them down
to firmware.

There's no need to ever include sys/conf.h here anymore, so remove
it. It was added years ago as a transition and everything has been
updated.

enum disk_ioctl is unused. It's only ever defined. All of the stand

* Use explicit casts when assigning `unsigned char *` to `char *` or vice versa
* Drop unused global variables (and fix memory leak in `gettable()`)
* Use `snprintf()` instead of `strcpy()` + `strcat()`

Deprovision feature of waagent is used for preparing to capture a
running VM and turn it into a VM image. Using it in the process of
building a VM image from scratch will cause some side effects such as
the hostname of the building host getting reset.
Remove calling the deprovision command and use a simpler way to fulfill
the requirements of the Azure VM image.

There's been a report recently of mbufs with data that crosses a page
boundary. It seems those mbufs are generated by the iSCSI target
system:
https://lists.xenproject.org/archives/html/xen-devel/2021-12/msg01581.html
In order to handle those mbufs correctly on netfront use the bus_dma
interface and explicitly request that segments must not cross a page
boundary. No other requirements are necessary, so it's expected that
bus_dma won't need to bounce the data and hence it shouldn't
introduce a too big performance penalty.
Using bus_dma requires some changes to netfront, mainly in order to
accommodate for the fact that now ring slots no longer have a 1:1
match with mbufs, as a single mbuf can use two ring slots if the data
buffer crosses a page boundary. Store the first packet of the mbuf
chain in every ring slot that's used, and use a mbuf tag in order to
store the bus_dma related structures and a refcount to keep track of
the pending slots before the mbuf chain can be freed.

Now that vtblk uses busdma, it keeps important information inside its
request structures. The functions used for kernel dumps synthesize
their own request structures rather than using structures initialized
with the necessary bits for busdma.
Add busdma-bypass paths. Since dumping writes contiguous blocks of
physical memory, vtblk doesn't need busdma in that case.
