net: Declare a macro to define stacks used by networking

Browse source 
The macro defines the stack as usual, but if user has
enabled net shell (CONFIG_NET_SHELL), then additional
information about the stack is stored in net_shell
linker section. The information in the net_shell linker
section is then used to print information about the
stacks in the networking sub-system.
