Improve MANIFEST.MF parsing

Browse Source 
Previously, we would only properly parse LF-encoded manifests, and even
those only if they used the recommended casing.

This commit allows the parser to recognise CR and CRLF newlines, and
also makes the name comparison case insensitive to align with the
specification. (Though not completely: we still don't support multiline
values)
