19ab8c6fb0 Fix the handbook install option in bsdinstall 
bsdconfig's f_package_add doesn't seem to support using the pkg repo from /etc/pkg/FreeBSD.conf, it also tries to run the commands on the installer image, not in the destination chroot

Instead, manually bootstrap pkg in the chroot, and then install the requested packages (in the chroot)

Doesn't use pkg -c, because pkg is not installed on the installer image

cd363583ce Give AHCI disk serial based on backing file path same as for virtio block.

15ba37b7de Rewrite virtio block device driver to work asynchronously and use the block 
I/O interface.

Asynchronous operation, based on r280026 change, allows to not block virtual
CPU during I/O processing, that on slow/busy storage can take seconds.
Use of recently improved block I/O interface allows to process multiple
requests same time, that improves random I/O performance on wide storages.

Benchmarks of virtual disk, backed by ZVOL on RAID10 pool of 4 HDDs, show
~3.5 times random read performance improvements, while no degradation on
linear I/O.  Guest CPU usage during test dropped from 100% to almost zero.

42641f98a6 Modify virtqueue helpers added in r253440 to allow queuing. 
Original virtqueue design allows queued and out-of-order processing, but
helpers added in r253440 suppose only direct blocking in-order one.
It could be fine for network, etc., but it is a huge limitation for storage
devices.

eb63aed246 Give block I/O interface multiple (8) execution threads. 
On parallel random I/O this allows better utilize wide storage pools.
To not confuse prefetcher on linear I/O, consecutive requests are executed
sequentially, following the same logic as was earlier implemented in CTL.

Benchmarks of virtual AHCI disk, backed by ZVOL on RAID10 pool of 4 HDDs,
show ~3.5 times random read performance improvements, while no degradation
on linear I/O.
