* Source-level incompatibility: rename QUtil::strcasecmp to
QUtil::str_compare_nocase. This is a non-compatible change, but
QUtil::strcasecmp is hardly the most important part of qpdf's API.
The reason for this change is that strcasecmp is a macro on some
systems, and that was causing problems when QUtil.hh was included
in certain circumstances. Fixes #242.
