Ideally we would like txg_kick() to get triggered only when we are sure
that we are not syncing AND not quiescing any txg. This way we can kick
an open TXG to the quiescing state when we are sure that there is nothing

Newer versions of gcc generate "might not be initialized" warnings for
several variables in nfsrpc_doiods(). I have checked and all of these
variables are assigned values before they are used.
In the one case of "tdrpc", it could have passed garbage as an argument
to nfscl_dofflayoutio() when mirrorcnt is one. However nfscl_dofflayoutio() only
uses the argument when mirrorcnt > 1, so it wasn't actually broken.
This patch initializes "tdrpc" to avoid confusion and initializes the rest
to make the compiler happy.

Various components restrict size of IO passed up to the userspace filesystem
based on the mount's f_iosize value. The previous default of PAGE_SIZE
is anemic, even for normal filesystems, but especially considering every
FUSE operation involves a kernel <-> userspace IPC upcall.
Bump to DFLTPHYS (currently 64kB) to match other FUSE implementations.
Anecdotally, Jakub reports IO read performance increased from 600 MB/s ->
2700 MB/s with a basic RAM-backed FUSE filesystem.

The images were renamed from KERNCONF to BOARDNAME when
specified, which would result in an image name of:
12.0-CURRENT-arm-armv7-GENERIC.img
which would then be renamed to use the BOARDNAME for the
SoC the image is targeted to use. BOARDNAME was specified
for all images as of r336994, which now causes the ftp-stage

Add the ioctl PCIOCBARMMAP on /dev/pci to conveniently create
userspace mapping of a PCI device BAR. This is enormously superior to
read the BAR value with PCIOCREAD and then try to mmap /dev/mem, and
should allow to automatically activate the mapped BARs when needed in
future.
Current implementation creates new sg pager for each user mmap
request. If the pointer (and reference) to a managed device pager is
stored in pci_map, we would be able to revoke all mappings on the BAR
deactivation or relocation. This is related to the unimplemented BAR
activation on mmap, and is postponed for the future.

Mounting of filesystems in "filesystem/local" is done using `zfs mount -a`,
which mounts each filesystems serially. The bottleneck for each mount is
the I/O done to load metadata for each filesystem. As such, mounting
filesystems using a parallel algorithm should be a big win, and bring down
the runtime of "filesystem/local"'s start method.
