@sebsura I implemented what I think the both of us settled on. Would you mind taking another look? |

dist-tarball.sh was supposed to create "clean" tarballs, that is with a path-prefix of bareos-x.y.z based on the version-number. This didn't happen as rewriting in tar did not take place. With this patch the paths provided to tar are now all prefixed with './' which allows the substitution to work correctly.
when the unix_tape_device encounters a block that is too large for the buffer to handle, it will now re-read with incrementing buffer sizes until it can provide the first part of the block. This allows Bareos to reconfigure the block buffer size for tape devices like it already does for file devices.
When bsr() is called to initiare a re-read on a tape, it will decrement ths block_num. As during the re-read the block_num was not incremented, it shouldn't be decremented.

This change allows Bareos to read tape volumes even if the configured
Maximum Block Sizeis too small.You will still see an error message like this to notify you that something is not right:
However, restore will not fail anymore.
Please check
