* Skip slow tests on (very) slow test targets.
* Set Makefile SHELL as determined by configure.
This should improve compatibility for users with non-POSIX shells. If
using Makefile.in directly (eg make -f Makefile.in distprep) then SHELL
will need to be specified on the command line (along with MANFMT in that
particular case). ok djm@
* Use bash or ksh if available for SH in Makefile.
* Increase test timeout to allow slow VMs to finish
* Only run regression tests on slow VMs.
* Only return events from ppoll that were requested.
If the underlying system's select() returns bits that were not in the
request set, our ppoll() implementation can return revents for events
not requested, which can apparently cause a hang. Only return revents
for activity in the requested event set. bz#3416, analysis and fix by
yaroslav.kuzmin at vmssoftware com, ok djm@
* Specify TEST_SHELL=bash on AIX.
The system shells cause the agent-restrict test to fail due to some
quoting so explicitly specify bash until we can get configure to
autmatically work around that.

main clauses

* Capture stderr output from configure.
* Only refuse to use OpenSSL 3.0.4 on x86_64.
The potential RCE only impacts x86_64, so only refuse to use it if we're
targetting a potentially impacted architecture. ok djm@
* Remove special casing of crypt().
Configure goes to some lengths to pick crypt() from either libcrypt
or OpenSSL's libcrypto because they can more or less featureful (eg
supporting md5-style passwords).
OpenSSL removed its crypt() interface in 2002:
https://github.com/openssl/openssl/commit/69deec58 so these hijinks
should no longer be necessary. This also only links sshd with libcrypt
which is the only thing that needs it. ok djm@
* Clarify README.md text.
Clarify the text about the implications of building without OpenSSL, and
prefix the "configure --help" example command with a "./" so it's likely
to work as-is in more shells. From bz#3461.
* Split README.platform into its own line.
README.platform has general platform-specific information, having it
following text about FIDO2 on the same line could imply that it only
has information about FIDO2.
* Return ERANGE from getcwd() if buffer size is 1.
If getcwd() is supplied a buffer size of exactly 1 and a path of "/", it
could result in a nul byte being written out of array bounds. POSIX says
it should return ERANGE if the path will not fit in the available buffer
(with terminating nul). 1 byte cannot fit any possible path with its nul,
so immediately return ERANGE in that case.
OpenSSH never uses getcwd() with this buffer size, and all current
(and even quite old) platforms that we are currently known to work
on have a native getcwd() so this code is not used on those anyway.

* Do not link scp, sftp and sftp-server w/ zlib.
Some of our binaries (eg sftp, sftp-server, scp) do not interact with
the channels code and thus do use libraries such as zlib and libcrypto
although they are linked with them. This adds a CHANNELLIBS and starts
by moving zlib into it, which means the aformentioned binaries are no
longer linked against zlib. ok djm@
* Group libcrypto and PRNGD checks together.

* Move stale-configure check as early as possible.
We added a check in Makefile to catch the case where configure needs to

fido_dev_is_winhello.
* Actually put HAVE_STDINT_H around the stdint.h.
* Rename our getentropy to prevent possible loops.
Since arc4random seeds from getentropy, and we use OpenSSL for that
if enabled, there's the possibility that if we build on a system that
does not have getentropy then run on a system that does have it, then
OpenSSL could end up calling our getentropy and getting stuck in a loop.

Also allow certificate validity intervals to be specified in raw

user identity before completing the signing/authentication attempt.
Whether or not user verification was performed is already baked into the
signature made on the FIDO token, so this is just plumbing that flag
through and adding ways to require it.

Previously we didn't do this because we didn't want to expose
the attack surface presented by USB and FIDO protocol handling,
but now that this is insulated behind ssh-sk-helper there is
less risk.

This directive has a single valid option "no-touch-required" that
causes sshd to skip checking whether user presence was tested before
a security key signature was made (usually by the user touching the
key).

refactor channels.c
Move static state to a "struct ssh_channels" that is allocated at
runtime and tracked as a member of struct ssh.
Explicitly pass "struct ssh" to all channels functions.
Replace use of the legacy packet APIs in channels.c.
Rework sshd_config PermitOpen handling: previously the configuration
parser would call directly into the channels layer. After the refactor
this is not possible, as the channels structures are allocated at
connection time and aren't available when the configuration is parsed.
The server config parser now tracks PermitOpen itself and explicitly
configures the channels code later.
