Issue #23529 : Limit the size of decompressed data when reading from
...
GzipFile, BZ2File or LZMAFile. This defeats denial of service attacks
using compressed bombs (i.e. compressed payloads which decompress to a huge
size).

Make lzma.{encode,decode}_filter_properties private.
...
These functions were originally added to support LZMA compression in the zipfile
module, and are not of interest for the majority of users.
They can be made public in 3.4 if there is user interest, but in the meanwhile,
I've opted to present a smaller, simpler API for the module's initial release.
