This commit resolves https://github.com/rfjakob/gocryptfs/issues/850 by addressing Unicode normalization mismatches on macOS between NFC (used by CLI tools) and NFD (used by GUI apps). The solution is inspired by Cryptomator's approach ( https://github.com/cryptomator/cryptomator/issues/264 ). Forward mode on MacOS now enforces NFC for storage but presents NFD as recommended by https://developer.apple.com/library/archive/qa/qa1173/_index.html and https://github.com/macfuse/macfuse/wiki/File-Names-(Unicode-Normalization-Forms) . See https://github.com/rfjakob/gocryptfs/pull/949 for more info. This commit does nothing for reverse mode as it is not clear if anything can be done. Reverse mode can not influence how the file names are stored, hence mapping normalized names back to what is actually on disk seems difficult.

Use MaxInt32 instead, which is good enough, even on amd64. It only has to be larger than any name we might encounter.
