9.1.1: release

• Bug fix: in qdf mode, do not write out any XRef streams that may have appeared in the original file. These are usually unreferenced, but with --preserve-unreferenced, they could be written out, which breaks fix-qdf's assumption that there is at most one XRef stream and that it appears at the end of the file.

• Bug fix: when externalizing inline images, a colorspace value that was a lookup key in the page's /Resource -> /ColorSpace dictionary was not properly handled.

• Add "encrypt" key to the json output. This contains largely the same information as given by --show-encryption but in a consistent, parseable format.

• Add options --is-encrypted and --requires-password. These can be used with files, including encrypted files with unknown passwords, to determine whether or not a file is encrypted and whether a password is required to open the file. The --requires-password option can also be used to determine whether a supplied password is correct. Information is supplied through exit codes, making these options particularly useful for shell scripts.

• Fix for Windows being unable to acquire crypt context with a new keyset.

• Rewrite fix-qdf in C++. This means fix-qdf is a proper executable now, and there is no longer a runtime requirement on perl.

• Add QUtil::call_main_from_wmain, a helper function that can be called in the body of wmain to convert UTF-16 arguments to UTF-8 arguments and then call another main function.

• QUtil::read_lines_from_file: add new versions that use FILE*, use FILE* instead if std::ifstream internally to support correct handling of Unicode filenames in Windows, and add the option to preserve line endings.
