* Fixed a few minor warnings like the following:

cipher_funcs.c:85: warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result

A few of these were in code in the lib/ directory, and required adding a
new error code 'FKO_ERROR_FILESYSTEM_OPERATION' and associated error
string 'Read/write bytes mismatch'.
