Allow prefixing typical strings with L for wide strings and u for unicode strings.

It likely wasn't applied because it did not show up in patchwork correctly, due to the patch being inline:
https://lore.kernel.org/patchwork/patch/842121/
In any case, it needed rebasing and updating to support 'u'.
I sent this upstream:
https://lore.kernel.org/patchwork/patch/1470668/
(no changes since v3)
Changes in v3: - Mention the link to the new upstream patch
Changes in v2: - Add new patch to reduce checkpatch unicode-string spam
