ed5f847c38 loader: nandfs calls strategy with one extra argument. 
The strategy argument cleanup in r310850 did miss another call to strategy(),
and left it with extra argument.

2bcaf52fce dosfs support in libstand is broken since r298230 
Apparently the libstand dosfs optimization is a bit too optimistic
and did introduce possible memory corruption.

This patch is backing out the bad part and since this results in
dosfs reading full blocks now, we can also remove extra offset argument
from dv_strategy callback.

The analysis of the issue and the backout patch is provided by Mikhail Kupchik.

c26598f6f0 libstand: make more use of the howmany() macro when available. 
We have a howmany() macro in the <sys/param.h> header that is
convenient to re-use as it makes things easier to read.

e44e2ac96c Add a divisor parameter to twiddle() so that callers can request that output 
only happen on every Nth call.  Update the existing twiddle() calls done in
various IO loops to roughly reflect the relative IO sizes.  That is, tftp
and nfs call twiddle() on every 1K block, ufs on every filesystem block,
so the network calls now use a much larger divisor than disk IO calls.

Also add a new twiddle_divisor() function that allows an application to set
a global divisor that is applied on top of the per-call divisors.  Nothing
calls this yet, but loader(8) will be using it to further throttle the
cursor for slow serial consoles.

92a73b39ae Fix nandfs support by providing the same crc32 function as is used 
in newfs_nandfs. In libstand we get crc32 from libz. The polynomial
is not the same as used for nandfs, which is the crc32 used in the
kernel.

6f7c735300 Import work done under project/nand (@235533) into head. 
The NAND Flash environment consists of several distinct components:
  - NAND framework (drivers harness for NAND controllers and NAND chips)
  - NAND simulator (NANDsim)
  - NAND file system (NAND FS)
  - Companion tools and utilities
  - Documentation (manual pages)

This work is still experimental. Please use with caution.
