[bufaux.c buffer.h kex.c kex.h kexc25519.c kexc25519c.c kexc25519s.c]
[kexdhc.c kexdhs.c kexecdhc.c kexecdhs.c kexgexc.c kexgexs.c]
avoid use of OpenSSL BIGNUM type and functions for KEX with
Curve25519 by adding a buffer_put_bignum2_from_string() that stores
a string using the bignum encoding rules. Will make it easier to
build a reduced-feature OpenSSH without OpenSSL in the future;
