Instead of the convoluted logic, simply use a small number of LUTs
that point to the available compressor flags for each compressor,
the avaialble options and their ranges.

Every compressor (except LC4) has a compression level parameter. This
commit pulls the compression level field out into the generic
configuration structure and applies some code clean ups as a result
from this.

The LZMA compressor (through the xz-utils library) supports basically
the same options for micro management as the XZ compressor.
This commit enables support for those options in the compressor, the
option parser and adds an option field to the configuration structure.

This patch allows external users to fiddle with the XZ compressors
compression strength, alignment and other values.

Avoid namespace polution. Make sure all exportet symbols are prefixed
with either sqfs_ or SQFS_.

The XZ option parser had a similar function to parse_size. This commit
removes the other implementation and extends parse_size with the one
missing feature, i.e. allowing a '%' suffix for a relative value.

That is IMO less confusing and express what it is (i.e. what it has
become) more clearly, i.e. common code shared by the utilities.
