Embedded lzma decompression library becomes a module usable by other consumers, in addition to geom_uzip. Most important code changes are - removal of XZ_DEC_SINGLE define, we need the code to work with XZ_DEC_DYNALLOC; - xz_crc32_init() call is removed from geom_uzip, xz module handles initialization on its own. xz is no longer embedded into geom_uzip, instead the depend line for the module is provided, and corresponding kernel option is added to each MIPS kernel config file using geom_uzip. The commit also carries unrelated cleanup by removing excess "device geom_uzip" in places which were missed in r344479.
