bpo-21872: fix lzma library decompresses data incompletely (GH-14048)
...
* 1. add test case with wrong behavior
* 2. fix bug when max_length == -1
* 3. allow b"" as valid input data for decompress_buf()
* 4. when max_length >= 0, let needs_input mechanism works
* add more asserts to test case

bpo-37707: Exclude expensive unit tests from PGO task (GH-15009)
...
Mark some individual tests to skip when --pgo is used. The tests
marked increase the PGO task time significantly and likely don't
help improve optimization of the final executable.

GzipFile, BZ2File or LZMAFile. This defeats denial of service attacks
using compressed bombs (i.e. compressed payloads which decompress to a huge
size).

#19395 : Raise exception when pickling a (BZ2|LZMA)(Compressor|Decompressor).
...
The underlying C libraries provide no mechanism for serializing compressor and
decompressor objects, so actually pickling these classes is impractical.
Previously, these objects would be pickled without error, but attempting to use
a deserialized instance would segfault the interpreter.

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.
