compress: Do not put newlines on error messages

In the oops function text is appended onto the end of the supplied error
message, so newlines appear in the middle of error messages. This patch
removes all newlines from supplied error messages.

compress: Return error messages correctly from compress_open

The allocated compress object will be freed and bad_compress will be
returned, so error messages written to the allocated compress struct
will be lost. This patch writes error messages to bad_compress for error
paths in compress_open, ensuring that error messages are returned
correctly.

compress: Extend limit on error messages

32 characters is a very short size for the error message, extend this
to 128 characters to prevent clipping on the majority of messages.
