make SSHBUF_DBG/SSHBUF_TELL (off by default and only enabled via
#define) dump to stderr rather than stdout

make sshbuf_putb(b, NULL) a no-op

allow sshbuf_put_stringb(buf, NULL); ok markus@

lots of things were relying on libcrypto headers to transitively
include various system headers (mostly stdlib.h); include them
explicitly

add some functions to perform random-access read/write operations
inside buffers with bounds checking. Intended to replace manual
pointer arithmetic wherever possible.

fix casts re constness

Include stdarg.h for va_copy as per man page.

Compare pointers to NULL rather than 0.

avoid BIGNUM in KRL code by using a simple bitmap;

apparently memcpy(x, NULL, 0) is undefined behaviour according to
C99 (cf. sections 7.21.1 and 7.1.4), so check skip memcpy calls when
length==0; ok markus@

convert KRL code to new buffer API

ok markus@

New buffer API; the first installment of the conversion/replacement
of OpenSSH's internals to make them usable as a standalone library.

This includes a set of wrappers to make it compatible with the
existing buffer API so replacement can occur incrementally.

Dempsky and Ron Bowes for a detailed review.
