------------------------------
- ISetProperties::SetProperties:
it's possible to specify desirable number of CPU threads:
PROPVARIANT: name=L"mt", vt = VT_UI4, ulVal = NumberOfThreads
If "mt" is not defined, 7za.dll will check number of processors in system to set
number of desirable threads.
Now 7za.dll can use:
2 threads for LZMA compressing
N threads for BZip2 compressing
4 threads for BZip2 decompressing
Other codecs use only one thread.
Note: 7za.dll can use additional "small" threads with low CPU load.
