try to avoid extra syscalls when reading sockets
so far we shifted down the buffered data only when we ran out of space.
however, that may cause chopping up the actual socket read, which is a
bad trade-off with avoiding a moderate-sized memmove. so try to keep
enough space for the anticipated read size.
note that this ignores the zlib path, as that always does full-size
socket reads into z_buf, and saving inflate() calls seems pointless.
