9a25b1d942 Improve performance/reduce allocs of bytespipe
Creates a `fixedBuffer` type that is used to encapsulate functionality
for reading/writing from the underlying byte slices.

Uses lazily-loaded set of sync.Pools for storing buffers that are no
longer needed so they can be re-used.

3f5b8f712d Extract StreamConfig struct out of the daemon package.
This is a small configuration struct used in two scenarios:

1. To attach I/O pipes to a running containers.
2. To attach to execution processes inside running containers.

Although they are similar, keeping the struct in the same package
than exec and container can generate cycled dependencies if we
move any of them outside the daemon, like we want to do
with the container.
