Jing Chen 7cc17225e6 Remove references to math/rand package's Read function. 
The helper function is deprecated. The package gvisor.dev/gvisor/pkg/rand
depends on crypto/rand which performs worse thatn math/rand, the changes
are fine since they are not at any gVisor's hot path.

The ultimate goal is to migrate math/rand to math/rand/v2.

Jing Chen cf5c4c9cbf Replace reflect.DeepEqual with [slices/maps].Equal. 
They are faster on slice/map comparisons.

Kevin Krakauer c006f01e0e rename bufferv2 to buffer 
The old buffer has been dead for a while. We use type aliases so we can switch
package names in smaller CLs.

Lucas Manning a13fbe75e4 Remove the old version of buffer. 
This is no longer used anywhere in gVisor. Everything has been migrated to
bufferv2.

Ting-Yu Wang 84f04cc858 Migrate PacketBuffer to use pkg/buffer 
Benchmark iperf3:
                    Before      After
native->runsc       5.14        5.01    (Gbps)
runsc->native       4.15        4.07    (Gbps)

It did introduce overhead, mainly at the bridge between pkg/buffer and
VectorisedView, the ExtractVV method. Once endpoints start migrating away from
VV, this overhead will be gone.

Updates #2404
