Avoid signed overflow in fmt_scaled
Adding the scaled fractional part to whole may result in a signed overflow.
Guard against this by adding checks before subtracting or adding.

ecdh: add error codes for point at infinity/not on curve
The point at infinity would previously raise EC_R_POINT_AT_INFINITY via
EC_POINT_get_affine_coordinates(). For consistency, also raise an error
for off-curve points.

switch nfs_getreq() to nfsd_adv()
from miod@ ok jsg@
This round of commits was prompted by a double-free report
from Andrew Griffiths at Calif.
server nfs request mbuf pointers were stored in two structs:
nmi_mrep in struct nfsm_info
nd_mrep in struct nfsrv_descript
but only set to NULL after m_freem() in nmi_mrep
This problem is avoided by removing the use of struct nfsm_info
in the server paths and passing struct nfsrv_descript to
new versions of the nfsm functions.
