+LzmaRamEncode: BCJ + LZMA RAM->RAM compressing.
+It uses .lzma format, but it writes one additional byte to .lzma file:
+ 0: - no filter
+ 1: - x86(BCJ) filter.
+
+To provide best compression ratio dictionarySize mustbe >= inSize
+
+LzmaRamEncode allocates Data with MyAlloc/BigAlloc functions.
+RAM Requirements:
+ RamSize = dictionarySize * 9.5 + 6MB + FilterBlockSize
+ FilterBlockSize = 0, if useFilter == false
+ FilterBlockSize = inSize, if useFilter == true
+
+ Return code:
+ 0 - OK
+ 1 - Unspecified Error
+ 2 - Memory allocating error
+ 3 - Output buffer OVERFLOW
+
+If you use SZ_FILTER_AUTO mode, then encoder will use 2 or 3 passes:
+ 2 passes when FILTER_NO provides better compression.
+ 3 passes when FILTER_YES provides better compression.
