bug#22912: url-util: add url-hexify-region, url-unhex-region

	Just like there’s, say, encode-coding-region, interactive
	url-unhex-region and its inverse come handy at times.  Say, one
	may stumble upon a URI like [1], which is hardly legible without
	applying url-unhex-region first.

	Please thus consider adding functions like those MIMEd to
	url-util.el.

There's url-unhex-string and url-hexify-string already in url-util, so
these seem superfluous.
