* Make UTF-8 decoding errors in .cabal files non-fatal
Previously we checked for invalid UTF-8 in the first phase of the
parser, which splitting the file up into nested sections and fields.
This meant the whole parser falls over if there is invalid UTF-8
anywhere in the file. Sadly there are already packages on hackage
with invalid UTF-8 so we would fail when parsing the hackage index.
The solution is to move the check into the parsing of the individual
fields and making it a warning not an error. We most typically get
invalid UTF-8 in free text fields like author name, copyright,
description etc so this should work out ok usually.
We now get pretty decent error messages, like:
Warning: hsx.cabal:5: Invalid UTF-8 text in the 'author' field.
The warning type is now structured so that hackage will be able to
distinguish general non-fatal warnings from UTF-8 decoding problems
which really should be fatal errors for package uploads.
