Add support for the fixed image type. The fixed image is effectively
a raw image with a VHD footer appended. There's little value that I
can see to use the fixed image type, but in order to make VHD images
for use by Microsoft's Azure platform, they must be fixed VHD images.

Support has been added by refactoring the code to re-use common code
and by adding a second output format structure.  To created fixed VHD
images, specify "vhdf" as the output format.
Remove the man page for a pmap function that no longer exists.
Replace all uses of libncurses and libtermcap with their wide character
variants.  This allows usable file system images (i.e. those with both a
shell and an editor) to be created with only one copy of the curses library.

Add a man page for the new function pmap_unwire().
Reduce per-LUN memory usage from 18MB to 1.8MB.

CTL never had use for CA support code since SPI has gone, and there is no
even frontends supporting that.  But it still was reserving 256 bytes of
memory per LUN per every possible initiator on every possible port.

Wrap unused code with ifdef's in case somebody even need it.

Increase maximal number of SCSI ports in CTL from 32 to 128.

After I gave each iSCSI target its own port, the old limit appeared to be
not so big.  This change almost proportionally increases per-LUN memory
use, but it is still three times better then it was before r268807.
