Adds a new bpf_setsockopt for TCP sockets, TCP_BPF_WINDOW_CLAMP,
which sets the maximum receiver window size. It will be useful for
limiting receiver window based on RTT.

This patch contains support to set tcp window_field field from bpf setsockops.
v2: Used TCP_WINDOW_CLAMP setsockopt logic for bpf_setsockopt (review comment
addressed)
v3: Created a common function for duplicated code (review comment addressed)

No reason in particular.
Updated the code (patch v2) to have logic as tcp setsockopt for
tCP_WINDOW_CLAMP.
PS: First time trying git send-em,ail, pleas elet me know if this is not the
right way to reply.
