remove post-SSHv1 removal dead code from rsa.c and merge
the remaining bit that it still used into ssh-rsa.c; ok markus

fix regression in 7.4: deletion of PKCS#11-hosted keys
would fail unless they were specified by full physical pathname. Report and
fix from Jakub Jelen via bz#2682; ok dtucker@

add a whitelist of paths from which ssh-agent will load
(via ssh-pkcs11-helper) a PKCS#11 module; ok markus@

Add MAXIMUM(), MINIMUM(), and ROUNDUP() to misc.h, then
use those definitions rather than pulling <sys/param.h> and unknown namespace
pollution. ok djm markus dtucker

fix signed/unsigned errors reported by clang-3.7; add
sshbuf_dup_string() to replace a common idiom of strdup(sshbuf_ptr()) with
better safety checking; feedback and ok markus@

Add a function to enable security-related malloc_options.
With and ok deraadt@, something similar has been in the snaps for a while.

Add "id" to ssh-agent pledge for subprocess support.
Found the hard way by Jan Johansson when using ssh-agent with X. Also,
rearranged proc/exec and retval to match other pledge calls in the tree.

fflush stdout so that output is seen even when running in
debug mode when output may otherwise not be flushed. Patch from dustin at
null-ptr.net.

Use a salted hash of the lock passphrase instead of plain
text and do constant-time comparisons of it. Should prevent leaking any
information about it via timing, pointed out by Ryan Castellucci. Add a 0.1s
incrementing delay for each failed unlock attempt up to 10s. ok markus@

Replace <sys/param.h> with <limits.h> and other less
dirty headers where possible. Annotate <sys/param.h> lines with their
current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1,
LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of
MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution.
These are the files confirmed through binary verification. ok guenther,
millert, doug (helped with the verification protocol)
Add FingerprintHash option to control algorithm used for
key fingerprints. Default changes from MD5 to SHA256 and format from hex to
base64.

Clear buffer used for handling messages. This prevents keys being
left in memory after they have been expired or deleted in some cases
(but note that ssh-agent is setgid so you would still need root to
access them). Pointed out by Kevin Burns, ok deraadt

Add support for Unix domain socket forwarding. A remote TCP port
may be forwarded to a local Unix domain socket and vice versa or
both ends may be a Unix domain socket. This is a reimplementation
of the streamlocal patches by William Ahern from:

Only cleanup agent socket in the main agent process and not in any
subprocesses it may have started (e.g. forked askpass). Fixes
agent sockets being zapped when askpass processes fatal();

Dempsky and Ron Bowes for a detailed review a few months ago.
NB. This commit also removes portable OpenSSH support for OpenSSL
<0.9.8e.
