* This fixes booting on virtualbox with UEFI, where it
fails to identify CDs as BOOT_METHOD_CD, such that the
write_overlay driver doesn't get loaded, causing a
panic in the kernel trying to mount the boot device.

On VirtualBox, the reported maximum transfer size is 2MB; but all
I/O >= 753KB fails in an identical way to the "maximum size" failures.
In other news, there are multiple open tickets in the VirtualBox
tracker about Linux systems failing to boot off NVMe...
I tested with a hacked-in maximum segment size of 752KB and everything
seemed to work just fine. Writing a HPKG to a FAT partition on NVMe,
rebooting, and then reading back the HPKG showed it had the same
sha256sum as the one stored in /system did. So this is working!
Before this commit, only one qpair was allocated and it was
locked for the duration of the transfer. Now we allocate more
qpairs if the device supports it and lock only when actually
calling read(), enabling multiple reads to both be queued
and execute simultaneously.
This is probably a significant performance improvement,
even more so than it is/would be for SCSI, as SSDs
can actually read from as many sectors as bandwidth
allows at once.
* Modeled after pppconfig to some degree.
* Normally various VPN and other services will create / manage
tunnels directly, however this gives us a good way to
test / play with things initially.
As the comment implies, we don't want to wait here, but low_resource()
waits forever when timeout=0. It doesn't seem to do anything with the
"size" argument at all, so not calling it is just as effective, and so
replace the comment there altogether.
The case where this was most often hit, causing a full system deadlock
in anything relating to memory management, was when the passed "size"
was 0. So now we check for this case explicity at the beginning and
panic() on KDEBUG kernels for it.
This is the cause of #14557. It seems that OpenBSD does the same thing.
I didn't read the spec yet to determine precisely what this means,
so for now, just do what OpenBSD does and bail.
This only seems to happen with a secondary XHCI controller on that
device, so hopefully most USB ports will still work.
The previous version did not account for the position not being a
multiple of the block size, among other problems.
Tested by hand with DiskProbe and then "dd skip=..." to read single
bytes from partial blocks, and validated as correct.
Only one qpair is used for reading, which is rather inefficient.
We currently allocate a bounce buffer for every allocation, which is
also inefficient, due to the fact that we must read an integer multiple
of LBAs.
But it does work, and it is actually reasonably fast, even on an emulated
machine using a spinning-disk-backed NVMe device (88MB/s.)
I wasn't able to get it working in non-packaged, though; the device manager
called supports_device() on a number of PCI devices, but not the NVMe
device, so I have a different version with a hack that grabs the PCI info
manually. I didn't test inside haiku.hpkg yet; perhaps it will work in there.
Previously it was possible that we put() them twice, leading to
assert-failure panics as their ref-counts would go below 0.
Now we get() them once for every bus object that we create, as
the destructors put() them.
Should fix the panic in #15004.

It is called before them (and is responsible for calling them),
so having it in the middle of the file does not make a lot of sense.
Already done for XHCI. Only one functional change -- removing the
set_dprintf_enabled call. Drivers probably shouldn't spuriously
re-enable that if it was specifically disabled.
Some time back the menu item 'Partition | Initilize' changed to 'Format'.
The format dialog's button label still says 'Initialize'.
Change to 'Format' for consistency.
