There's still some interest in the btrfs-debugfs tool, make it work with
python v3 until we have a replacement.

The values for block group offset, length etc. in btrfs-debugfs' output
are left-aligned, which creates unaligned output and makes the usage
percentage hard to read/process further. This patch adds right-aligning
format specifiers for the number values.
Ideally the format values wouldn't be hardcoded but instead derived from
the filesystem size, but this seems to work for now.

This aims to decide whether a balance can reduce the number of
data block groups and if it is, this shows the '-dvrange' block
group's objectid.

This is a starting point for a debugfs style python interface using
the search ioctl. For now it can only do one thing, which is to
print out all the extents in a file and calculate the compression ratio.
Over time it will grow more features, especially for the kinds of things
we might run btrfs-debug-tree to find out. Expect the usage and output
to change dramatically over time (don't hard code to it).
