Bug #43104 ndb_mgmd - error message with newline(s) breaks mgmapi protocol

Description:
Error messages in ndb_mgmd that are supposed to be returned to mgmapi should not contain newline(\n) since that will break the mgapi protcol that uses newline as line separator.

How to repeat:
.

Suggested fix:
Remove the newlines in error messages that will be transfered over the wire to mgmapi. It would also be possible to base64 encode the errormessage, but that would break backward compatibility.

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

Documented bugfix in the NDB-6.2.17, 6.3.23, and 6.4.3 changelogs as follows:

        Some error messages from ndb_mgmd that contained newline (\n)
        characters. This could break the MGM API protocol, which uses
        the newline as a line separator.
