374cab6390 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-
rewriting in __cwd results in wrong entries in %directories under certain
circumstances, e.g. when a test executes run(app(["openssl"]) after indir.

There should not be any need to go to a higher directory from BLDDIR or SRCDIR,
so it should be OK to use them in their absolute form, also resolving all
possible symlinks, right from the start.

Following the File::Spec::Functions bug description (reported to perl.org):

When abs2rel gets a path argument with ..s that are crossing over the ..s
trailing the base argument, the result is wrong.

Example
PATH: /home/goal/test/..
BASE: /home/goal/test/../../base
Good result: ../goal
Bad  result: ../..

Bug verified with File::Spec versions
- 3.6301
- 3.74 (latest)

f987a4dd89 man: clarify the 'random number generator must be seeded' requirement
The manual pages require for some API functions that the 'random number
generator must be seeded' before calling the function.  Initially, this
was meant literally, i.e. the OpenSSL CSPRNG had to be seeded manually
before calling these functions.

Since version 1.1.1, the CSPRNG is seeded automatically on first use,
so it's not the responsibility of the programmer anymore.  Still, he
needs to be aware that the seeding might fail.

915430a0a9 Move 'shared_sigalgs' from cert_st to ssl_st
It was only ever in cert_st because ssl_st was a public structure
and could not be modified without breaking the API.  However, both
structures are now opaque, and thus we can freely change their layout
without breaking applications.  In this case, keeping the shared
sigalgs in the SSL object prevents complications wherein they would
inadvertently get cleared during SSL_set_SSL_CTX() (e.g., as run
during a cert_cb).

Fixes #9099

This reverts commit 524006dd1b.

While this change did prevent the sigalgs from getting inadvertently
clobbered by SSL_set_SSL_CTX(), it also caused the sigalgs to not be
set when the cert_cb runs.  This, in turn, caused significant breakage,
such as SSL_check_chain() failing to find any valid chain.  An alternate
approach to fixing the issue from #7244 will follow.

9863b41989 Add regression test for #9099
Augment the cert_cb sslapitest to include a run that uses
SSL_check_chain() to inspect the certificate prior to installing
it on the SSL object.  If the check shows the certificate as not
valid in that context, we do not install a certificate at all, so
the handshake will fail later on in processing (tls_choose_sigalg()),
exposing the indicated regression.

Currently it fails, since we have not yet set the shared sigalgs
by the time the cert_cb runs.

d8bb277f76 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.

860fed97aa 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.

2813852d71 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.

ad416c8058 Revert the DEVRANDOM_WAIT feature
The DEVRANDOM_WAIT feature added a select() call to wait for the
`/dev/random` device to become readable before reading from the
`/dev/urandom` device. It was introduced in commit 38023b87f0
in order to mitigate the fact that the `/dev/urandom` device
does not block until the initial seeding of the kernel CSPRNG
has completed, contrary to the behaviour of the `getrandom()`
system call.

It turned out that this change had negative side effects on
performance which were not acceptable. After some discussion it
was decided to revert this feature and leave it up to the OS
resp. the platform maintainer to ensure a proper initialization
during early boot time.

Fixes #9078

This partially reverts commit 38023b87f0.

8f75443f99 Document deprecation of version-specific SSL/TLS methods
In commit 2b8fa1d56c the version-specific SSL/TLS methods were
deprecated. This patch improves the documentation of that change
by stating the deprecation more prominently in the manual page
and explaining the reason for the deprecation.

Fixes #8989

a069bdf0aa build_SYS_str_reasons: Fix a crash caused by overlong locales
The 4 kB SPACE_SYS_STR_REASONS in crypto/err/err.c isn't enough for some locales.
The Russian locales consume 6856 bytes, Ukrainian even 7000.

build_SYS_str_reasons() contains an overflow check:

if (cnt > sizeof(strerror_pool))
    cnt = sizeof(strerror_pool);

But since commit 9f15e5b911 it no longer
works as cnt is incremented once more after the condition.

cnt greater than sizeof(strerror_pool) results in an unbounded
OPENSSL_strlcpy() in openssl_strerror_r(), eventually causing a crash.

When the first received error string was empty or contained only
spaces, cur would move in front of the start of the strerror_pool.

Also don't call openssl_strerror_r when the pool is full.
