bpo-40280: Skip more tests/features that don't apply to Emscripten (GH-31791)
- fd inheritance can't be modified because Emscripten doesn't support subprocesses anyway.
- setpriority always fails
- geteuid no longer causes problems with latest emsdk
- umask is a stub
- geteuid / getuid always return 0, but process cannot chown to random uid.

bpo-45863: tarfile: don't zero out header fields unnecessarily (GH-29693)
Numeric fields of type float, notably mtime, can't be represented
exactly in the ustar header, so the pax header is used. But it is
helpful to set them to the nearest int (i.e. second rather than
nanosecond precision mtimes) in the ustar header as well, for the
benefit of unarchivers that don't understand the pax header.

Add test for tarfile.TarInfo.create_pax_header to confirm correct
behaviour.

bpo-39039: tarfile raises descriptive exception from zlib.error (GH-27766)
* during tarfile parsing, a zlib error indicates invalid data
* tarfile.open now raises a descriptive exception from the zlib error

  corrupted tar file

bpo-41316: Make tarfile follow specs for FNAME (GH-21511)
tarfile writes full path to FNAME field of GZIP format instead of just basename if user specified absolute path. Some archive viewers may process file incorrectly. Also it creates security issue because anyone can know structure of directories on system and know username or other personal information.

RFC1952 says about FNAME:
This is the original name of the file being compressed, with any directory components removed.

So tarfile must remove directory names from FNAME and write only basename of file.

bpo-40275: More lazy imports in test.support (GH-20131)
Make the the following imports lazy in test.support:

* bz2
* gzip
* lzma
* resource
* zlib

The following test.support decorators now need to be called
with parenthesis:

* @support.requires_bz2
* @support.requires_gzip
* @support.requires_lzma
* @support.requires_zlib

For example, "@requires_zlib" becomes "@requires_zlib()".

bpo-18819: tarfile: only set device fields for device files (GH-18080)
The GNU docs describe the `devmajor` and `devminor` fields of the tar
header struct only in the context of character and block special files,
suggesting that in other cases they are not populated. Typical utilities
behave accordingly; this patch teaches `tarfile` to do the same.

* add requires_hashdigest to test.support to check if a hash digest algorithm is available and working
* avoid MD5 in test_hmac
* replace MD5 with SHA256 in test_tarfile
* mark network tests that require MD5 for MD5-based digest auth or CRAM-MD5

bpo-35772: Fix test_tarfile on ppc64 (GH-11606)
Fix sparse file tests of test_tarfile on ppc64le with the tmpfs
filesystem.

Fix the function testing if the filesystem supports sparse files:
create a file which contains data and "holes", instead of creating a
file which contains no data.

tmpfs effective block size is a page size (tmpfs lives in the page
cache). RHEL uses 64 KiB pages on aarch64, ppc64 and ppc64le, only
s390x and x86_64 use 4 KiB pages, whereas the test punch holes of
4 KiB.

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.
