stateful codecs without the stream API). Functions

Add ending new-line to all source files.

Replaced the tis_620, cp1140 and koi8_u codecs with new ones
based on custom mapping files.

These new codecs include and use character decoding tables which speeds
up decoding by a few factors.

codec files to codecs.py and added logic so that multi mappings
in the decoding maps now result in mappings to None (undefined mapping)
in the encoding maps.

codec to not apply Latin-1 mappings for keys which are not found
in the mapping dictionaries, but instead treat them as undefined
mappings.

The patch was originally written by Martin v. Loewis with some
additional (cosmetic) changes and an updated test script
by Marc-Andre Lemburg.

The standard codecs were recreated from the most current files
available at the Unicode.org site using the Tools/scripts/gencodec.py
tool.

This patch closes the bugs #116285 and #119960.
