Since LIBC 2.28 fmul exists in math.h, without this commit
we will have following errors during build with _GNU_SOURCE
define:

In file included from OS_portable.h:80,
                 from OS_nonportable.c:34:
../includes/curve25519.h:43:9: error: conflicting types for 'fmul'
 bits320 fmul(const bits320 in2,const bits320 in);
         ^~~~

- myinfo->notarymutex and myinfo->dpowmutex seems sometimes
initialised not correctly. as a result we had following
debug messages:

[ Decker ] ./dpow/dpow_network.c.1480 (dpow_addnotary): ip = 149.56.30.227
[ Decker ] ./dpow/dpow_network.c.1481 (dpow_addnotary): err_unlock = 22
[ Decker ] ./dpow/dpow_network.c.1418 (dpow_addnotary): ip = x.x.x.x
[ Decker ] ./dpow/dpow_network.c.1419 (dpow_addnotary): err_lock = 22
[ Decker ] ./dpow/dpow_network.c.1480 (dpow_addnotary): ip = x.x.x.x
[ Decker ] ./dpow/dpow_network.c.1481 (dpow_addnotary): err_unlock = 22
[ Decker ] ./dpow/dpow_network.c.1418 (dpow_addnotary): ip = 149.56.30.227

where 22 means [EINVAL]
The value specified by mutex does not refer to an initialized mutex object.

And finally it leads to app crash:

iguana: ../nptl/pthread_mutex_lock.c:433: __pthread_mutex_lock_full: Assertion `INTERNAL_SYSCALL_ERRNO (e, __err) != ESRCH || !robust' failed.

So, we changed these mutexes to:

myinfo->dpowmutex -> def_dpowmutex
myinfo->notarymutex -> def_notarymutex

with initialisation with PTHREAD_MUTEX_INITIALIZER .
