Specifically, if you were using attribute references:

if (&Attribute =~ /my regex/) {

}

The raw value of the attribute will be used without any pre-escaping.

This applies not just to regexes but all comparisons.

update request {
	Tmp-String-0 := '"foo"'
}

Can now be matched with:

if (&Tmp-String-0 := '"foo"') {

Instead of:

if (&Tmp-String-0 := '\"foo\"') {

Using the raw value however means that values with embedded \0s can cause issues.

Most of the comparison code has been fixed, but there's still problems with regexes,
due to the POSIX functions (regcomp, regexec), not taking a length argument.

There are non-POSIX extensions (regncomp, renexec), but they're not in the PCRE
compatibility library, so we've got to consider what to do there.

If your strings/regexes don't contain/deal with unprintables or double quotes, no
changes are required.
