Adding fenv support for ARM

Crap! The default mode <sys/fenv.h> is working is turning the methods into
static inline which conflicts with the default implementation. That's what
is happening.
Cut the static inline bodies out of the arm sys/fenv.h and distribute them
to libm/arm/XXX.c based on their method name. Drop __fenv_static
completely.
Make the new split out feXXX.c files FreeBSD copyright. You should add a
note that you adapted them from their sys/fenv.h with static inline to have
the bodies in separate files. Make the same type of note in the arm
sys/fenv.h.
Sorry to beat the copyright/credit thing but it is important to note that
the meat of the code came from FreeBSD and you split it into files.
