[Bug libc/2681] New: BRF encoding (braille)

[samuel dot thibault at ens-lyon dot org]

BRF (Braille Format), aka ASCII Braille, is a usual way of encoding formated braille texts, ready to submit to a braille embosser.  One can find a lot of .brf file on internet, so it would be very helpful to have this encoding in iconv.  Attached is a simple table-based implementation (not tested, but generated from brltty tools) with a test-case (written by hand and tested with brltty tools).

Note: there are duplicates.

Strict BRF only defines 0x00-0x5f: 0x00-0x1f for usual ascii commands,
and 0x20-05f is bijective with 6-dots patterns.

In addition to that, a-z{}|~`\x7f are usually defined as I described
in the table because it often happens that .brf files (erroneously)
include some of them.

Mmm, thanks to a debian snapshot, I could realize that duplicates pose problem. Here are files without duplicates, which actually got tested.
