fusefrontend: rewrite Lseek SEEK_DATA / SEEK_HOLE
...
In response to the discussion of the xfstests mailing list [1],
I looked at the Lseek implementation, which was naive and
did not handle all cases correctly.
The new implementation aligns the returned values to 4096 bytes
as most callers expect.
A lot of tests are added to verify that we handle all
cases correctly now.

Microbenchmarks (values below) show that the "SingleDev"
case is now much slower due to an extra map lookup,
but this has no visible effects in ./test.bash results,
so there was no time spent optimizing the case further.
