of sys/param.h in special __FreeBSD__ section, since this file is

Make import work; do I/O in image native block size.
Note: creating sparse images is not currently attempted; could
scan for runs of zeros and write discontiguous chunks to image.

Detect a misordered ondisk tmap... if we are already decoding it. We still
leave the trailing bits unchecked.

The MDS may include RM ops in a tmap update for items that were already
removed: after restarting and replaying the journal, it doesn't know
which dentries were previously committed and which were not.
No other (known) users care about the error code.

The previous tmap implementation requires that the update stream be
sorted or else it will behave erratically (by placing new keys in the
map out of order). This can cause very strange failures: reads may
appear to return the correct result initially, but once intervening
keys are remove they will not... depending on how read is implemented
on the client side.
Fix this by doing the optimized updates initially, but falling back to
a slow implementation if an unsorted update is detected. It is slow,
but such updates are rare.

import allows specifying one image, implicitly or explicitly the
"source" image, even though it's really the destination. Fix up
the reassignment of 'source' to 'dest', and check for and complain
about specifying two different pools or images for import.

User-space tool that interacts with the monitor, with the objective of
generating a workload mimicking a set of OSDs and clients.
As it is, the tool will mimic any number of OSDs, by keeping in-memory
stubs that will act as independent OSDs, generating random operations
that will induce map updates; the client stub, on the other hand,
performs no operations besides connecting to the monitor and whatever
happens between the Objecter class and the monitor (mainly keeping
updated with map updates).

Before we only allowed buckets (say, 'root') to be defined *before*
rules.
With this patch, we allow buckets and rules to be defined by any order,
although some care should be taken when creating the plain-text crush
map, or the crushtool will error out when a rule uses a bucket only
defined later on in the file.

'verbose' was a bool that would either be passed as one or zero to class
CrushCompile. However, most messages would only be outputted with a
verbose level > 1.
This patch makes it so that multiple '-v' increase the verbosity level;
i.e., -v mean verbose = 1; -v -v means verbose = 2; and so forth.
