It should be in r->headers_in->accept.  Please note that 
NGX_HTTP_HEADERS have to be defined for the whole nginx build, not 
just your module.

Alternatively, you may just lookup $http_accept variable via 
ngx_http_get_variable().  This will work even without 
NGX_HTTP_HEADERS defined (and will trigger logic in 
ngx_http_variable_unknown_header_in() for arbitrary http header 
lookup).
