Summary Reduce fragmentation of small uncached network resources

Small resources fetched over the network can end up on their own VM page, leading to internal fragmentation since the default page size on some devices is 16KB. Mitigate this by copying small resources to malloc'd memory. This is a ~0.3% win on Membuster5.
