Default the read block size (-k default value) to kern.maxphys (usually
...
64k these days). This gives a noticable performance boost on large filesystems.

range-check what we assign to int cachebufs from calculations with
...
uint64_t usermem. This only becomes relevant if you have several TB of RAM.
Promoting cachebufs to uint64_t is not necessary as it gets limited to
(currently) 512 anyway.
fixes the last issue of PR: 19852

The sysctl returning the amount of memory in the system returns "int",
...
which is silly. Luckily, it really does return the correct result if
interpreted as an unsigned int. This change lets dump work on 32-bit
systems that have more than 2GB of RAM.

Bump daddr_t to 64 bits. Replace it with int32_t in all places where

it was used on-disk, so that on-disk formats remain the same.
Remove ufs_daddr_t and ufs_lbn_t for the time being.

In rawread(), add back a check to ensure that dump doesn't try to read
...
past EOM and fail with "short read error". This check was part of
traverse.c::bread(), and was removed when that function was migrated
to rcache.c::rawread() as part of the "read cache" functionality.
This should fix the problem with dump barfing on "short read" when "-r 0",
but I'm still debugging the problem where dump gets to a point and
"does nothing" when the read cache is being used.
