The pure-Lua ustring pattern matching functions short-circuit to the
much faster string library when the pattern would match the same against
the raw bytes.
A pattern like "[^a-z]" can match a partial UTF-8 character when applied
bytewise, and so must be detected as unsafe.
Let's also directly test the pure-Lua module, instead of me having to
comment out lines in Scribunto_LuaUstringLibrary::register() whenever I

The "%f[set]" frontier pattern has been in Lua 5.1 since the beginning,
but was undocumented until Lua 5.2. And the code is even unchanged from
5.1.0 to 5.2.1. So there's no reason not to implement it in ustring too.
Note the changes to UstringLibrary.php are somewhat large, because it
splits the "convert a Lua bracketed charset to PCRE" code into a
separate function and it changes the handling of mw.ustring.find's and
mw.ustring.match's 'init' parameter from "substring, match from 0, then
add back on $init" to "use preg_match's $offset and use \G instead of ^
where this matters". Both of these are necessary to properly support
%f.
This also fixes a bug in the pure-Lua code (not used in Scribunto)
exposed by the unit tests for %f where %z was matching '\1' rather than
'\0' and %Z everything except '\1' instead of everything except '\0'.
