     Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
     host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
     better performance than plain DH and DSA at the same equivalent symmetric
     key length, as well as much shorter keys.

     Only the mandatory sections of RFC5656 are implemented, specifically the
     three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
     ECDSA. Point compression (optional in RFC5656 is NOT implemented).

     Certificate host and user keys using the new ECDSA key types are supported.

     Note that this code has not been tested for interoperability and may be
     subject to change.

[auth-options.c auth1.c auth2.c bufaux.c buffer.h kex.c key.c packet.c]
     [packet.h ssh-dss.c ssh-rsa.c]
     Add buffer_get_cstring() and related functions that verify that the
     string extracted from the buffer contains no embedded \0 characters*
     This prevents random (possibly malicious) crap from being appended to
     strings where it would not be noticed if the string is used with
     a string(3) function.

     Use the new API in a few sensitive places.

     * actually, we allow a single one at the end of the string for now because
     we don't know how many deployed implementations get this wrong, but don't
     count on this to remain indefinitely.

     NB. portable commit contains everything *except* removing includes.h, as

[buffer.c buffer.h channels.c]
     Fix condition where we could exit with a fatal error when an input
     buffer became too large and the remote end had advertised a big window.
     The problem was a mismatch in the backoff math between the channels code
     and the buffer code, so make a buffer_check_alloc() function that the
     channels code can use to propsectivly check whether an incremental
     allocation will succeed.  bz #1131, debugged with the assistance of
     cove AT wildpackets.com; ok dtucker@ deraadt@
