Fix compilation on sparc64 by actually supplying the bus_dma_tag_t member
of the rx_ring to bus_dmamap_sync(9). Given that netmap code tries to
obtain the bus addresses of netmap buffers via vtophys(9) instead of using
bus_dma(9) it currently has zero chance of actually working on sparc64
though (and for that matter f.e. also not with MACs limited to 32-bit DMA
on x86 machines with more than 4GB of RAM).
From time to time people report space map corruption resulting in panic
(ss == NULL) on pool import. I had such a panic recently. With current version
of ZFS it is still possible to import the pool in readonly mode and backup
all the data, but in case it is impossible for some reason add tunable
vfs.zfs.space_map_last_hope, which when set to '1' will tell ZFS to remove
colliding range and retry. This seems to have worked for me, but I consider
it highly risky to use.

On start most of sysctl_kern_proc functions use the same pattern:

As the function may be useful not only in kern_proc.c it is in the

Correct a logic error in usr.bin/hexdump/conv.c, found by clang.
Whenever the conv_c() function encounters an incomplete multibyte char,
it peeks ahead. It also sets p to peekbuf, to indicate it is still
processing the incomplete character.
However, on the next retry, it compares buf against peekbuf, which
always returns false, since both buf and peekbuf are local char arrays,
whose addresses are never the same.
Fix this by comparing against p instead, which was the intention. Also
turn peekbuf into an array of u_char, to prevent conversion warnings.

introduce cngets, a method for kernel to read a string from console
This is intended as a replacement for libkern's gets and mostly borrows
its implementation. It uses cngrab/cnungrab to delimit kernel's access

Note: libkern's gets obviously doesn't share any bits of implementation
iwth libc's gets. They also have different APIs and the former doesn't
have the overflow problems of the latter.

kern cons: introduce infrastructure for console grabbing by kernel
At the moment grab and ungrab methods of all console drivers are no-ops.
Current intended meaning of the calls is that the kernel takes control of

the calling thread takes full ownership of the console (e.g. console
output from other threads could be suspended).
