William Chargin eab3b3f1c6 bpo-39389: gzip: fix compression level metadata (GH-18077)
As described in RFC 1952, section 2.3.1, the XFL (eXtra FLags) byte of a
gzip member header should indicate whether the DEFLATE algorithm was
tuned for speed or compression ratio. Prior to this patch, archives
emitted by the `gzip` module always indicated maximum compression.

guoci 0e7497cb46 bpo-34898: Add mtime parameter to gzip.compress(). (GH-9704)
Without setting mtime, time.time() will be used as the timestamp which will
end up in the compressed data and each invocation of the compress() function
will vary over time.

Replace KB unit with KiB (#4293)
kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte")
means 1024 bytes. KB was misused: replace kB or KB with KiB when
appropriate.

Same change for MB and GB which become MiB and GiB.

Change the output of Tools/iobench/iobench.py.

Round also the size of the documentation from 5.5 MB to 5 MiB.

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).
