[channels.c session.c]
bz#1750: fix requirement for /dev/null inside ChrootDirectory for
internal-sftp accidentally introduced in r1.253 by removing the code
that opens and dup /dev/null to stderr and modifying the channels code
to read stderr but discard it instead; ok markus@

authenticated (where our client will display them with LogLevel=debug).

[mux.c]
Correct sizing of object to be allocated by calloc(), replacing
sizeof(state) with sizeof(*state). This worked by accident since
the struct contained a single int at present, but could have broken

[PROTOCOL.certkeys auth-options.c ssh-keygen.c]
Move the permit-* options to the non-critical "extensions" field for v01
certificates. The logic is that if another implementation fails to
implement them then the connection just loses features rather than fails
outright.

[channels.c channels.h mux.c ssh.c]
Pause the mux channel while waiting for reply from aynch callbacks.
Prevents misordering of replies if new requests arrive while waiting.
Extend channel open confirm callback to allow signalling failure
conditions as well as success. Use this to 1) fix a memory leak, 2)
start using the above pause mechanism and 3) delay sending a success/
failure message on mux slave session open until we receive a reply from
the server.

[key.c servconf.c servconf.h sshd.8 sshd_config.5]
add some optional indirection to matching of principal names listed
in certificates. Currently, a certificate must include the a user's name
to be accepted for authentication. This change adds the ability to
specify a list of certificate principal names that are acceptable.
When authenticating using a CA trusted through ~/.ssh/authorized_keys,
this adds a new principals="name1[,name2,...]" key option.
For CAs listed through sshd_config's TrustedCAKeys option, a new config
option "AuthorizedPrincipalsFile" specifies a per-user file containing
the list of acceptable names.
If either option is absent, the current behaviour of requiring the
username to appear in principals continues to apply.
These options are useful for role accounts, disjoint account namespaces
and "user@realm"-style naming policies in certificates.

[sshconnect.c sshconnect2.c sshd.c]
revised certificate format ssh-{dss,rsa}-cert-v01@openssh.com with the
following changes:
move the nonce field to the beginning of the certificate where it can
better protect against chosen-prefix attacks on the signature hash
Rename "constraints" field to "critical options"
Add a new non-critical "extensions" field
Add a serial number
The older format is still support for authentication and cert generation
(use "ssh-keygen -t v00 -s ca_key ..." to generate a v00 certificate)
