71bb86f0dc Make sure that apps/openssl prefixes its output with '# ' during tests
The reason to do this is that some output might start with an 'ok',
which TAP catches and takes for TAP output.  The TAP compatible way is
to make all output it shouldn't catch look like comments.

We do this by setting the environment variable HARNESS_OSSL_PREFIX
during tests.  When that is set, apps/openssl uses BIO_f_linebuffer
and sets its prefix to the content of that environment variable.

d6baf09fe0 Apps: divide the modules in direct command modules, support library and init
Most modules are direct implementations of openssl application
sub-commands, but some constitute a support library, which can be used
by more than one program (and is, incidently, by test/uitest).

For practical purposes, we place the support library modules in a
private, static library.

Finally, there are some modules that don't have direct references in
the rest of the apps code, but are still crucial.  See them as some
kind of extra crt0 or similar for your platform.

dab2cd68e7 apps: Don't include progs.h in apps.h
Everything in apps includes apps.h, because that one declares apps
internal library routines.  However, progs.h doesn't declare library
routines, but rather the main commands and their options, and there's
no reason why the library modules should include it.

So, remove the inclusion of progs.h from apps.h and add that inclusion
in all command source files.

adeb4bc7a0 Restore clearing of init_lock after free
The behavior of resetting the init_lock value to NULL after
freeing it during OPENSSL_cleanup() was added as part of the
global lock commits that were just reverted, but there is desire
to retain this behavior for clarity.

It is unclear that the library would actually remain usable in
any form after OPENSSL_cleanup(), since the required re-initialization
occurs under a CRYPTO_ONCE check that cannot be reset at cleanup time.
That said, a NULL dereference is probably more friendly behavior
in these treacherous waters than using freed memory would be.

63ab5ea13b Revert the crypto "global lock" implementation
Conceptually, this is a squashed version of:

    Revert "Address feedback"

    This reverts commit 75551e07bd.

and

    Revert "Add CRYPTO_thread_glock_new"

    This reverts commit ed6b2c7938.

But there were some intervening commits that made neither revert apply
cleanly, so instead do it all as one shot.

The crypto global locks were an attempt to cope with the awkward
POSIX semantics for pthread_atfork(); its documentation (the "RATIONALE"
section) indicates that the expected usage is to have the prefork handler
lock all "global" locks, and the parent and child handlers release those
locks, to ensure that forking happens with a consistent (lock) state.
However, the set of functions available in the child process is limited
to async-signal-safe functions, and pthread_mutex_unlock() is not on
the list of async-signal-safe functions!  The only synchronization
primitives that are async-signal-safe are the semaphore primitives,
which are not really appropriate for general-purpose usage.

However, the state consistency problem that the global locks were
attempting to solve is not actually a serious problem, particularly for
OpenSSL.  That is, we can consider four cases of forking application
that might use OpenSSL:

(1) Single-threaded, does not call into OpenSSL in the child (e.g.,
the child calls exec() immediately)

For this class of process, no locking is needed at all, since there is
only ever a single thread of execution and the only reentrancy is due to
signal handlers (which are themselves limited to async-signal-safe
operation and should not be doing much work at all).

(2) Single-threaded, calls into OpenSSL after fork()

The application must ensure that it does not fork() with an unexpected
lock held (that is, one that would get unlocked in the parent but
accidentally remain locked in the child and cause deadlock).  Since
OpenSSL does not expose any of its internal locks to the application
and the application is single-threaded, the OpenSSL internal locks
will be unlocked for the fork(), and the state will be consistent.
(OpenSSL will need to reseed its PRNG in the child, but that is
an orthogonal issue.)  If the application makes use of locks from
libcrypto, proper handling for those locks is the responsibility of
the application, as for any other locking primitive that is available
for application programming.

(3) Multi-threaded, does not call into OpenSSL after fork()

As for (1), the OpenSSL state is only relevant in the parent, so
no particular fork()-related handling is needed.  The internal locks
are relevant, but there is no interaction with the child to consider.

(4) Multi-threaded, calls into OpenSSL after fork()

This is the case where the pthread_atfork() hooks to ensure that all
global locks are in a known state across fork() would come into play,
per the above discussion.  However, these "calls into OpenSSL after
fork()" are still subject to the restriction to async-signal-safe
functions.  Since OpenSSL uses all sorts of locking and libc functions
that are not on the list of safe functions (e.g., malloc()), this
case is not currently usable and is unlikely to ever be usable,
independently of the locking situation.  So, there is no need to
go through contortions to attempt to support this case in the one small
area of locking interaction with fork().

In light of the above analysis (thanks @davidben and @achernya), go
back to the simpler implementation that does not need to distinguish
"library-global" locks or to have complicated atfork handling for locks.

3faa07b582 Move decisions about whether to accept reneg into the state machine
If a server receives an unexpected ClientHello then we may or may not
accept it. Make sure all such decisions are made in the state machine
and not in the record layer. This also removes a disparity between the
TLS and the DTLS code. The TLS code was making this decision in the
record layer, while the DTLS code was making it later.

Finally it also solves a problem where a warning alert was being sent
during tls_setup_handshake() and the function was returning a failure
return code. This is problematic because it can be called from a
transition function - which we only allow fatal errors to occur in.

b1fafff631 Make configdata.pm runnable and move all display of information there
The "make variable" information displayed by Configure was selective
and incomplete, and possibly undesirable (too verbose).

Instead, we make configdata.pm and have the user run it to get the
information they desire, and also make it possible to have it perform
a reconfiguration.

Possibilities so far:

perl configdata.pm --dump               Displays everything (i.e. the
                                        combined output from

                                        --make-variables and
                                        --build-parameters.
perl configdata.pm --command-line       Displays the config command
                                        line.
perl configdata.pm --envirnoment        Displays the recorded
                                        environment variables.
perl configdata.pm --make-variables     Displays the configured "make
                                        variables".
perl configdata.pm --build-parameters   Displays the build file and
                                        the template files to create
                                        it.
perl configdata.pm --reconfigure        Re-runs the configuration with
                                        the recorded environment
                                        variables.

--verbose can be used to have --reconfigure be a bit more verbose.

8c3bc594e0 Processing GNU-style "make variables" - separate CPP flags from C flags
C preprocessor flags get separated from C flags, which has the
advantage that we don't get loads of macro definitions and inclusion
directory specs when linking shared libraries, DSOs and programs.

This is a step to add support for "make variables" when configuring.

36c91d13d1 Fix ssl-trace with TLS 1.3 draft-23 PSS sigalgs
The latest TLS 1.3 draft split the RSA-PSS signature schemes into
two versions that indicate the OID of the RSA key being used.
This forced us to rename the preprocessor defines for the sigalg
values, and the ssl-trace code was not adopted to match, since
it was not enabled int the default build.

Belatedly update the ssl_sigalg_tbl in the trace code to match.
