Don't skip parts of a file when calling fiemap
...
A mis-incremented offset in the fiemap-processing code meant that
non-sparse portions of files were missed.

Rename serve->has_control to serve->success.
...
This makes the use of this variable to signal an unexpected SIGTERM
while migrating less confusing.

Fixed build_allocation_map in ioutil.c to correctly traverse fiemaps where

there are more than 1000 extents in a 100MB file chunk.

Block allocation map is now built in a separate thread, and does not delay
...
server startup (sparse write avoidance doesn't happen until it is finished).
Added mutex to bitset functions, which were already being called from
multiple threads. Rewrote allocation map builder to request file
information in multiple chunks, to avoid uninterruptible wait and dynamic
memory allocation.

Error when reading sent data fails
...
If the client cuts off part-way through the write, it should cause an
error, not a fatal. Previously this happened if the open file had a
fiemap, but not if there was no allocation map. This patch fixes that,
along with an associated valgrind error.

Open files with O_DIRECT dependent on a compile-time DIRECT_IO #define.
...
O_DIRECT causes problems on (at least) a wheezy VM, and there are mixed
reports about its performance impact. This patch makes it a
compile-time choice which should remain until it's been benchmarked.

Enable writing after the 2G boundary
...
This patch fixes a bug in readwrite.c which truncated the 'from' field
in nbd requests. It was casting them down from an off64_t to an int.
