bpo-45229: Remove test_main in many tests (GH-28405)
Instead of explicitly enumerate test classes for run_unittest()
use the unittest ability to discover tests. This also makes these
tests discoverable and runnable with unittest.

load_tests() can be used for dynamic generating tests and adding
doctests. setUpModule(), tearDownModule() and addModuleCleanup()
can be used for running code before and after all module tests.

bpo-44439: BZ2File.write() / LZMAFile.write() handle buffer protocol correctly (GH-26764)
No longer use len() to get the length of the input data. For some buffer protocol objects,
the length obtained by using len() is wrong.

animalize 4ffd05d7ec 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.

Antoine Pitrou 2dbc6e6bce 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).

Patch by Martin Panter and Nikolaus Rath.

Nadeem Vawda e6514f533e #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.

Serhiy Storchaka 57f9b7a124 Issue #1159051: GzipFile now raises EOFError when reading a corrupted file

Nadeem Vawda a425c3d5a2 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.
