0001-Use-lseek-rather-than-writing-zeroes.patch [PATCH 1/4] Use lseek() rather than writing zeroes
The result will still be zeroes, but the file will be sparsely created.
This has the advantage that we use less space (if there are many failed
reads), but more importantly, also allows to go backwards in the file if
needs be.

To make this less ugly, move the operation also after the
offset/remaining reassignments.

0002-Implement-binary-search-for-skipping-over-bad-data.patch [PATCH 2/4] Implement binary search for skipping over bad data
Currently, dvdbackup has three options:
- Abort when encountering errors. This is not helpful.
- When encountering errors, skip over whatever we were trying to read
and move on to the next part. If the amount of unreadable data (in
this part of the DVD) is small, and we were at the beginning of the
buffer, this will throw away a lot of data.
- When encountering errors, assume it's just the current block that
fails and try to read the next. Since most DVD readers will already
retry reading blocks several times, which can take minutes with some
hardware, this mode takes forever if there are a large amount of
unreadable blocks.

This patch adds a binary search mode to reduce both the number of blocks
read as well as the amount of data lost.

It may still lose data if the buffer we're trying to read has two
contiguous areas of unreadable data. I've decided not to care about
that.
