freetdm: add __USE_BSD to ftdm_os, needed by unistd.h for usleep() and string.h to define strcasecmp()
	 add -Werror even when the compiler is unknown. This is just a work-around to gcc not being detected
	 as GNU by our current standalone build (not bootstrapped through FreeSWITCH)

lang: Update langs - Add pt_PT, update es to have es_ES and es_MX, update mod_say_es and add mod_say_pt (FS-2937)

	 ioctl interface in FreeBSD expects unsigned long

freetdm: ftmod_r2 - notify the core when we change the signaling status of a channel or span through the api

         mod_freetdm - created sigstatus api command
