Sage Weil 3ca02ef96e ceph: reset front len on return to msgpool; BUG on mismatched front iov
Reset msg front len when a message is returned to the pool: the caller
may have changed it.

BUG if we try to send a message with a hdr.front_len that doesn't match
the front iov.

Sage Weil 8f3bc053c6 ceph: warn on allocation from msgpool with larger front_len
Pass the front_len we need when pulling a message off a msgpool,
and WARN if it is greater than the pool's size.  Then try to
allocate a new message (to continue without failing).

Sage Weil 8fc91fd859 ceph: message pools
The msgpool is a basic mempool_t-like structure to preallocate
messages we expect to receive over the wire.  This ensures we have the
necessary memory preallocated to process replies to requests, or to
process unsolicited messages from various servers.
