delete nodes) could happen to leave B-Tree nodes with 0 count.

In the following hammer show result, there is repetition of
L14298648..14298661 pattern (which includes "BC") for another
25 times after below three. This structure tells nodes with
"BC" aren't generated by node split, because node split always
results in having at least two nodes (original and new node)
at the same level under the parent node of the original node.
It was probably generated by something happened after split.

The following path [B] seems to be the case that could genearate
this structure. As shown in [A] it usually recursively calls
node remove path against its parent node until it first hits
a parent with >1 count. However, as shown in [B] if it fails
to get a lock while in the recursive path, the path ends there
before it hits >1 count node. This results in losing a chance
to erase a node element within the first >1 count node that
has a pointer to all the children so far including the 0 count
node prune ioctl was originally trying to delete, and leaves
the 0 count node along with (1 or more) parent 1 count node(s).

hammer show should recognize this and not mark it as an error

sbin/hammer: Fix/refactor check_data_crc()

Separate inode CRC from other CRC checks.
The only reason this function goes into while(data_len) loop is
because HAMMER userspace can only support upto 16KB buffer data
whereas inode is always 128 byte.

CRC check should look something similar to the kernel function
hammer_crc_test_leaf() in order to keep maintainability.

Also blockmap_lookup() doesn't need to be inside the while loop.
It only needs to verify zone offset once for each record data.

Also use return value of blockmap_lookup() which is zone2 offset
instead of using non-zone2 offset for get_buffer_data().
get_buffer() does extra blockmap lookup if offset is not zone-2.

sbin/hammer: Add depth indentation option to hammer show

Print tab(s) based on the current depth in B-Tree. This makes
hammer show output look like below instead of having everything
without indentation. Depth indentation uses tabs instead of
whitespaces because using 0x20s greatly increases the size of
hammer show output.

This option can be specifed by (-vvv are optional)
 # hammer -vvvf /dev/da1:/dev/da2:/dev/da3 show none indent

With obfuscate option, it would be like
 # hammer -vvvf /dev/da1:/dev/da2:/dev/da3 show none indent,obfuscate

Note that this commit also changes hammer show's suboption format
mentioned above. Above examples are examples of the new format.
The format used to be as follows,
 hammer [getopt options] show [search directives] ["filter"/"nofilter"] ["obfuscate"]
but now it's
 hammer [getopt options] show [search directives] [comma separated suboptions]
The format mentioned in 337ec5f is obsolete. This was necessary
to keep simplicity of suboption format after search directives.

The comma separated suboptions (filter,nofilter,obfuscate,indent)
are not mentioned in hammer(8) manpage which means this change
doesn't impact anyone (aside from real users almost never use
this command in the first place). Having these suboptions just
makes easier to debug or examine the structure in certain cases.

The unzip utility isn't particularly necessary (the version of unzip in
ports is better), but the ports tree does leverage it extensively.  I've
been patching around all the resulting failures, but it's easier just to
import unzip(1) from FreeBSD and remove the ports tree modifications.

This tool has also been available in NetBSD since version 6.0, so maybe
bringing it into DragonFly will establish it as a standard BSD utility.
