Subject: Simplify the abilist format

The new format lists the version on each line, as in:

	VERSION SYMBOL TYPE [VALUE]

This makes it easier to process the files with line-oriented tools.

The abilist files were converted with this awk script:

/^[^ ]/ { version = $1 }
/^ / { print version, substr($0, 2) }

And sorted under the "C" locale with sort.
