* transcode.c (transcode_dispatch): reverted some of the changes
in r14746.
* transcode.c, enc/trans/single_byte.c: Added conversions to/from
US-ASCII and ASCII-8BIT (using data tables).
* enc/trans/single_byte.c: Some spacing/ordering changes due to
automatic data file generation.
* transcode_data.h, transcode.c: Preliminary code for using
micro-conversion functions.
* test/ruby/test_transcode.rb: Added some tests for US-ASCII and
ASCII-8BIT conversions.
