Patch: FYI: PRs 14358, 24552

[Tom Tromey]

I'm checking this in on the 4.0 branch.
I will put it on the trunk once it is open for bug fixes.

This fixes PRs 14358 and 24552.  It updates the encodings.pl script
and regenerates the list of encoding aliases.  It also adds a couple
new hand-maintained aliases.

	PR libgcj/14358, libgcj/24552:
	* gnu/gcj/convert/IOConverter.java: Regenerate aliases.  Add
	aliases for 'euc_jp' and 'eucjp'.
	* scripts/encodings.pl: Recognize 'none', not 'NONE'.  Include
	canonical names in output.
	(%map): Added UnicodeLittle and UnicodeBig.
