Unofficial version

This unofficial version adds the following changes from upstream v0.8.0:

Remove HL-DT-ST drives from LiteOn plugin blocklist, to enable error correction scan with HL-DT-ST WH16NS58 drive under firmware 1.V5, and probably others
Remove TSSTcorp drives from LiteOn plugin blocklist, to enable error correction scan with TSSTcorp SE-506CB drive under firmware TS02, and probably others
Fix LiteOn plugin for CD and DVD error scanning, was broken since upstream v0.7.2
Fix layer counting and layer size on BD, closes #3, bits taken from this patch
Fix read speed computation under high-speed BD drives (gettimeofday resolution was not enough, replaced with clock_gettime), closes #1
Fix some drives having only the maximum read speed available, closes #2
Fix erroneous detection of finalized BD-R as BD-ROM
Add a way to force the old LiteOn scanning way (by setting the LITEON_FORCE_OLD=1 env var)
Fix compilation under mingw-w64 (courtesy of Eli Bildirici, view patch)
Fix a few coding errors (thanks to compiler warnings)
