m/p/devicemapper: make parameter encoding part of package

The DM kernel interface gets a single parameter string for each DM
target in a table but internally the kernel immediately decodes it into
an argv-style list of string arguments. Because everything needs to do
it and it can be quite hard to get right, let's make it part of the
devicemapper package. Properly encoding this also means you get
actionable errors when you pass invalid data instead of weird kernel
errors or misbehavior.
