upstream commit
use sshbuf_allocate() to pre-allocate the buffer used for
loading keys. This avoids implicit realloc inside the buffer code, which
might theoretically leave fragments of the key on the heap. This doesn't
appear to happen in practice for normal sized keys, but was observed for
novelty oversize ones.
