Eric Blake 9d7ab222da nbd/server: Prefer heap over stack for parsing client names
As long as we limit NBD names to 256 bytes (the bare minimum permitted
by the standard), stack-allocation works for parsing a name received
from the client.  But as mentioned in a comment, we eventually want to
permit up to the 4k maximum of the NBD standard, which is too large
for stack allocation; so switch everything in the server to use heap
allocation.  For now, there is no change in actually supported name
length.
