test/evp_test.c: distinguish parsing errors from processing errors

Parsing functions are at liberty to return:

1:  when parsing on processing of the parsed value succeeded
0:  when the parsed keyword is unknown
-1: when the parsed value processing failed

Some parsing functions didn't do this quite right, they returned 0
when they should have returned -1, causing a message like this:

    Line 123: unknown keyword PeerKey

When this message (which is displayed when the parsing function
returns -1) would have been more appropriate:

    Line 123: error processing keyword PeerKey = ffdhe2048-2-pub

openssl dgst, openssl enc: check for end of input

The input reading loop in 'openssl dgst' and 'openssl enc' doesn't
check for end of input, and because of the way BIO works, it thereby
won't detect that the end is reached before the read is an error.
With the FILE BIO, an error occurs when trying to read past EOF, which
is fairly much ok, except when the command is used interactively, at
least on Unix.  The result in that case is that the user has to press
Ctrl-D twice for the command to terminate.

The issue is further complicated because both these commands use
filter BIOs on top of the FILE BIO, so a naïve attempt to check
BIO_eof() doesn't quite solve it, since that only checks the state of
the source/sink BIO, and the filter BIO may have some buffered data
that still needs to be read.  Fortunately, there's BIO_pending() that
checks exactly that, if any filter BIO has pending data that needs to
be processed.

We end up having to check both BIO_pending() and BIO_eof().

Thanks to Zsigmond Lőrinczy for the initial effort and inspiration.

Start up DEVRANDOM entropy improvement for older Linux devices.

Improve handling of low entropy at start up from /dev/urandom by waiting for
a read(2) call on /dev/random to succeed.  Once one such call has succeeded,
a shared memory segment is created and persisted as an indicator to other
processes that /dev/urandom is properly seeded.

This does not fully prevent against attacks weakening the entropy source.
An attacker who has control of the machine early in its boot sequence
could create the shared memory segment preventing detection of low entropy
conditions.  However, this is no worse than the current situation.

An attacker would also be capable of removing the shared memory segment
and causing seeding to reoccur resulting in a denial of service attack.
This is partially mitigated by keeping the shared memory alive for the
duration of the process's existence.  Thus, an attacker would not only need
to have called call shmctl(2) with the IPC_RMID command but the system
must subsequently enter a state where no instances of libcrypto exist in
any process.  Even one long running process will prevent this attack.

The System V shared memory calls used here go back at least as far as
Linux kernel 2.0.  Linux kernels 4.8 and later, don't have a reliable way
to detect that /dev/urandom has been properly seeded, so a failure is raised
for this case (i.e. the getentropy(2) call has already failed).

a cert and chain is compatible with the negotiated parameters. This could
be useful (for example) from the certificate callback. Unfortunately this

A local 'make clean' did some sweeping removals of files execpt for

An example is a symlink .dir-locals.el that would keep disappearing if

So we change this to leave all dotted files alone.  Our builds do not

Implement the GNU C library's random(3) pseudorandom number generator.
The algorithm is described: https://www.mscs.dal.ca/~selinger/random/

The rationale is to make the tests repeatable across differing platforms with
different underlying implementations of the random(3) library call.

More specifically: when executing tests with random ordering.

Don't generate an unnecessary Diffie-Hellman key in TLS 1.3 clients.

tls_parse_stoc_key_share was generating a new EVP_PKEY public/private
keypair and then overrides it with the server public key, so the
generation was a waste anyway. Instead, it should create a
parameters-only EVP_PKEY.

(This is a consequence of OpenSSL using the same type for empty key,
empty key with key type, empty key with key type + parameters, public
key, and private key. As a result, it's easy to mistakenly mix such
things up, as happened here.)

Fix default installation paths on mingw

Mingw config targets assumed that resulting programs and libraries are
installed in a Unix-like environment and the default installation
prefix was therefore set to '/usr/local'.

However, mingw programs are installed in a Windows environment, and
the installation directories should therefore have Windows defaults,
i.e. the same kind of defaults as the VC config targets.

A difficulty is, however, that a "cross compiled" build can't figure
out the system defaults from environment the same way it's done when
building "natively", so we have to fall back to hard coded defaults in
that case.

Tests can still be performed when cross compiled on a non-Windows
platform, since all tests only depend on the source and build
directory, and otherwise relies on normal local paths.

Adding Test.pm with workaround for Perl abs2rel bug

If SRCTOP != BLDTOP, and SRCTOP is given in relative form, e.g.
"./config ../openssl", then a bug in Perl's abs2rel may trigger that directory-

There should not be any need to go to a higher directory from BLDDIR or SRCDIR,

It was only ever in cert_st because ssl_st was a public structure

structures are now opaque, and thus we can freely change their layout

Following the previous 2 commits also move ecpointformats out of session

The previous 2 commits moved supported groups and ciphers out of the
session object to avoid race conditions. We now also move ecpointformats
for consistency. There does not seem to be a race condition with access
to this data since it is only ever set in a non-resumption handshake.
However, there is no reason for it to be in the session.

Fix a race condition in ciphers handling

Similarly to the previous commit we were storing the peer offered list
of ciphers in the session. In practice there is no need for this
information to be avilable from one resumption to the next since this
list is specific to a particular handshake. Since the session object is
supposed to be immutable we should not be updating it once we have decided
to resume. The solution is to remove the session list out of the session
object.

Fix a race condition in supported groups handling

In TLSv1.3 the supported groups can be negotiated each time a handshake
occurs, regardless of whether we are resuming or not. We should not store
the supported groups information in the session because session objects
can be shared between multiple threads and we can end up with race
conditions. For most users this won't be seen because, by default, we
use stateless tickets in TLSv1.3 which don't get shared. However if you
use SSL_OP_NO_TICKET (to get stateful tickets in TLSv1.3) then this can
happen.

The answer is to move the supported the supported group information into
the SSL object instead.

Fix error handling at openssl_strerror_r

When bufsize == 0, openssl_strerror_r should return 0 (if _GNU_SOURCE is defined),
to be consistent with non-_GNU_SOURCE variants, which exhibit the same behavior.
Fix a few cases, where the return value of openssl_strerror_r was ignored.
