pam_ssh:  Don't allow a bogus passphrase for unencrypted keys.

key_load_private() ignores the passphrase argument if the private key
is unencrypted.  This defeats the nullok check, because it means a
non-null passphrase will successfully unlock the key.

To address this, try at first to load the key without a passphrase.
If this succeeds and the user provided a non-empty passphrase *or*
nullok is false, reject the key.

libm: Sync with FreeBSD (~50 math functions added)

The main purpose of syncing with FreeBSD is to obtain numerous "long double"
functions which are required for C99 compliance.  There are still many
functions missing.  According to g++ testsuite, the following 10 functions
still must be implemented at least:
        coshl           logl            expl
        sinhl           log2l           expm1l
        acoshl          log10l
        asinhl          log1pl

most of several complex functions.

the NetBSD version.  It may be time to reverse that and sync the entire
libm with FreeBSD.  Right now the DragonFly libm is a mixture between the
two and it doesn't divide nicely.  All the rounding and rint functions from
NetBSD had to be thrown out as well as the "kernel" functions.  For the
short term this is okay, but in the long term it would be a good idea to
start tracking FreeBSD again.  They are maintaining this library more
frequently and adding more functions more rapidly than NetBSD, so it would
be good to piggy-back on that effort.

The man page will be committed separately.
