Sam Chesney e312ed5dcc Change to include iAP module header not conf 
The required iAP headers have been updated such
that they can now be included from C, which allows
us to build with a default string for
IAP_EA_NATIVE_TRANS_PROTOCOL_NAME when it has not
been defined in the user app rather than having
to error.
