eb0d8e708a upstream: support PKCS8 as an optional format for storage of
private keys, enabled via "ssh-keygen -m PKCS8" on operations that save
private keys to disk.

The OpenSSH native key format remains the default, but PKCS8 is a
superior format to PEM if interoperability with non-OpenSSH software
is required, as it may use a less terrible KDF (IIRC PEM uses a single
round of MD5 as a KDF).

4d28fa78ab upstream: When system calls indicate an error they return -1, not
some arbitrary value < 0.  errno is only updated in this case.  Change all
(most?) callers of syscalls to follow this better, and let's see if this
strictness helps us in the future.

bbc8af72ba upstream: In sshkey_in_file(), ignore keys that are considered for
being too short (i.e. SSH_ERR_KEY_LENGTH). These keys will not be considered
to be "in the file". This allows key revocation lists to contain short keys
without the entire revocation list being considered invalid.

54d022026a 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.

1195f4cb07 upstream commit
deprecate key_load_private_pem() and
 sshkey_load_private_pem() interfaces. Refactor the generic key loading API to
 not require pathnames to be specified (they weren't really used).

Fixes a few other things en passant:

Makes ed25519 keys work for hostbased authentication (ssh-keysign
previously used the PEM-only routines).

Fixes key comment regression bz#2306: key pathnames were being lost as
comment fields.
