I have optimized and hardened the code.

This compression block device is tested in the following
This is a simple DM target supporting inplace compression. Its best
suited for SSD. The underlying disk must support 512B sector size.
The target only supports 4k sector size.
Disk layout:
|super|...meta...|..data...|
Store unit is 4k (a block). Super is 1 block, which stores meta and
data size

As $(SHELL) doesn't include the -e option, any loop or other sequence
needs to include explicit checks for failing commands.

Fixes: cd21379b1
In any case where we recurse but don't mention $(MAKE) literally in
the recipe, we need to add a '+' at the start of the command to ensure
that parallel makes and various other options work properly.

As we use redirection to create the SVG file, even a failed conversion
will create the file and 'make' will consider it up-to-date if the
build is retried. We should delete it in case of failure.

Make targets that don't depend on Sphinx work without warnings about
missing Sphinx. 'make cleandocs' will work without Sphinx just fine, and
the targets that are no-ops for Sphinx should just be skipped. Move them
outside of the HAVE_SPHINX checks to take precedence over the .DEFAULT
