Fixed 32-bit limit bug in DiskWriteTask::checkErrors.
Refs: commit e13f841a8c21d35f1bf75dc63d8c98b21d8dd8cb in castor/master

Fixed negative number representation in memory when casting int32 to
int64. The problem occurs when using readtp with out of order fseqs.

CASTOR-4909: tapeserverd tries to unmount the tape when the mount
failed...

Made the ignoring of exception throw by DriveGeneric::waitUntilReady
more specific: we now ignore timeouts, but not the other exceptions.

With respect to crc32c, modified error logs so that they are different
in different contexts

Fixed late conversion to float which led to rounding errors when evaluating
per file write transfer speed.

CASTOR-5419: Ceph aborts when writing a 0-sized buffer

Prevented writes of zero size in DiskWriteTask. They happen
when we read from tape a file aligned with the memory block size.

This is needed as getopt is not thread safe. This will allow usage of getopt to parse CTA command lines.
