mmap writes advance valid_size.
- Make valid_size and zeroed_size atomic to prevent torn reads and lost
updates. Hold the invalidate lock during truncation, and drain
in-flight direct I/O before buffered writes, buffered fallback, and
page-cache operations that extend valid_size.
- Fall back to single-cluster allocation when a buffered write cannot
allocate its entire range, allowing writes to consume the remaining
free space and return a short count.

Bulk delegation recall now adjusts the number of delegations it
wants returned, based on memory pressure. The previous mechanism
was spec-conformant, but it requested all delegations to be
returned at once. Clients are free to return few or none in such
cases, but requesting smaller batches of delegations is more
neighborly.
In preparation for handling TLS KeyUpdate, the server's TCP
receive path has been reworked to handle control records. In the
process, the use of sock_recvmsg was replaced with ->read_sock,
which contends less with other holders of the socket lock.
