sbin/hammer - Remove trailing '/' from paths.

When operating PFSes through symbolic links, it was not
possible to specify the trailing backslash since that
translated to the PFS root dir instead of the symbolic link
to the PFS itself. This caused problems when upgrading or
downgrading PFSes (and probably in other cases too).
The error was "Directory not empty".

This commit should solve those cases, but keep in mind
there are other cases where it is actually not possible
to complete certain operations (like while destroying
PFSes).

hammer(8): add HAMMER_RSH environment variable support.

Add support for a HAMMER_RSH environment variable which can be used
to select an alternate remote shell to be used for hammer remote operations,
change remote shell invocation to rsh(1) style '-l user host' instead of
ssh-style user@host to permit usage of rsh(1) as an alternate HAMMER_RSH
without the need for a wrapper script. Also change exec call of subshell
to use execvp instead of a hardcoded path to facillitate this change.

Update hammer.8 docs, along with minor formatting fix to environment
variable summary header sentence.

hammer - Add ssh-remote directive

* Adds a feature that allows you to set up a command="..." prefix for a
ssh key in your ~/.ssh/authorized_keys file that only runs the hammer
utility and only with specific commands and filesystem paths.

For example:

command="/sbin/hammer ssh-remote mirror-read,mirror-write /path/" ssh-rsa...

Currently requires a trailing '/' if you want to restrict the path to
a subdirectory. Multiple commands can be listed but the filesystem path
restriction is only currently tested for mirror-read and mirror-write.

* This allows ssh to be used for mirroring without having to give shell
access to the remote.

HAMMER Utility - Refactor the histogram code for mirror-stream.

* Refactor the histogram code. This code is responsible for breaking
down a large initial mirroring stream into smaller chunks so the
transaction id can be synced more often. This way if the stream
is interrupted it can be restarted at a more recent point instead
of having to restart further back (or at the beginning).

for the histogram.

HAMMER Util - Add new features, fix history retention bug in prune

* The prune code was not retaining the fine-grained history between
the last snapshot and current.

* Add a new PFS config variable called 'prune-min' which may be used
to set the minimum fine-grained history retention, in seconds. The
hammer prune code will not prune inbetween any snapshots that are
within the fine-grained retention period.

* The mirror-stream directive now automatically loops and reconnects
if the network connection fails.

* The mirror-stream directive now attempts to break-up a large initial
bulk transfer into smaller transfers, inserting synchronization points
so a failure in the middle of the large bulk transfer does not require
starting from scratch again.

* The show directive (show btree) now takes an optional localization[:objid]
argument (specified in hex). If specified the directive will search
the B-Tree for the key, printing nodes as it goes, and then continue
with a normal iteration.
