cc3200: Move wlan socket glue functions from modwlan to modusocket.
It saves about 400 bytes of code space because the functions can now be inlined.

// The following set of macros and functions provide a glue between the CC3100
|
||||
// simplelink layer and the functions/methods provided by the usocket module.
|
||||
// They were historically in a separate file because usocket was designed to
|
||||
// work with multiple NICs, and the wlan_XXX functions just provided one
|
||||
// particular NIC implementation (that of the CC3100). But the CC3200 port only
|
||||
// supports a single NIC (being the CC3100) so it's unnecessary and inefficient
|
||||
// to provide an intermediate wrapper layer. Hence the wlan_XXX functions
|
||||
// are provided below as static functions so they can be inlined directly by
|
||||
// the corresponding usocket calls.
