ERR_print_errors_cb() used functionality that isn't suitable any more,

ERR_func_error_string() essentially returns NULL, and since all
function codes are now removed for all intents and purposes, this
function has fallen out of use and cannot be modified to suit the
data, since its only function is to interpret an error code.
To compensate for the loss of error code, we instead provide new
functions that extracts the function name strings from an error
record:
- ERR_get_error_func()
- ERR_peek_error_func()
- ERR_peek_last_error_func()
Similarly, the once all encompasing functions
ERR_peek_last_error_line_data(), ERR_peek_error_line_data() and
ERR_get_error_line_data() lack the capability of getting the function
name string, so we deprecate those and add these functions to replace
them:
- ERR_get_error_all()
- ERR_peek_error_all()
- ERR_peek_last_error_all()
Finally, we adjust a few lines of code that used the now deprecated
functions.

The configuration option 'no-err' is documented to be used to avoid
loading error related string tables. For some reason, it was also
used to define if ERR_PUT_error() would pass the source file name and
line information or not.
The configuration option 'no-filenames' is documented to be used to
avoid passing the source file name and line anywhere. So, the
definition of ERR_PUT_error() should depend on OPENSSL_NO_FILENAMES
rather than OPENSSL_NO_ERR.
Furthermore, the definition of OPENSSL_FILE and OPENSSL_LINE depends
on if OPENSSL_NO_FILENAMES is defined or not, so there was never any
need to do extra macro gymnastics in include/openssl/err.h, so we
simply remove it and use OPENSSL_FILE and OPENSSL_LINE directly.
Finally, the macro OPENSSL_FUNC is unaffected by all these
configuration options, so it should be used in all macros that call
ERR_set_debug().

The output C code was made to use ERR_func_error_string() to see if a
string table was already loaded or not. Since this function returns
NULL always, this check became useless.
Change it to use ERR_reason_error_string() instead, as there's no
reason to believe we will get rid of reason strings, ever.
To top it off, we rebuild all affected C sources.

This includes a complete rework of how we use TAP::Harness, by adding
a TAP::Parser subclass that allows additional callbacks to be passed
to perform what we need. The TAP::Parser callbacks we add are:
ALL to print all the TAP output to a file (conditionally)
to collect all the TAP output to an array (conditionally)
EOF to print all the collected TAP output (if there is any)
if any subtest failed
To get TAP output to file, the environment variable HARNESS_TAP_COPY
must be defined, with a file name as value. That file will be
overwritten unconditionally.
To get TAP output displayed on failure, the make variable VERBOSE_FAILURE
or VF must be defined with a non-emoty value.
Additionally, the output of test recipe names has been changed to only
display its basename.

The module with_fallback.pm was kind of clunky and required a transfer
module. This change replaces if with a much more generic pragma type
module, which simply appends given directories to @INC (as opposed to
the 'lib' pragma, which prepends the directories to @INC).
This also supports having a file MODULES.txt with sub-directories to
modules. This ensures that we don't have to spray individual module
paths throughout our perl code, but can have them collected in one
place.
(do note that there is a 'fallback' module on CPAN. However, it isn't
part of the core perl, and it has no support the any MODULES.txt kind
of construct)

It is undefined behaviour to send NULL as either the src, or dest params
in memcpy.
In pkey_kdf.c we had a check to ensure that the src address is non-NULL.
However in some situations it is possible that the dest address could also
be NULL. Specifically in the case where the datalen is 0 and we are using
a newly allocated BUF_MEM.
We add a check of datalen to avoid the undefined behaviour.

Since commit 7c226dfc43 a chained DRBG does not add additional

the size of the additional data exceeded the allowed size when
no derivation function was used.
This commit provides an alternative fix: instead of adding the
entire DRBG's complete state, we just add the DRBG's address
in memory, thereby providing some distinction between the different
DRBG instances.

When the new OpenSSL CSPRNG was introduced in version 1.1.1,
it was announced in the release notes that it would be fork-safe,
which the old CSPRNG hadn't been.
The fork-safety was implemented using a fork count, which was
incremented by a pthread_atfork handler. Initially, this handler
was enabled by default. Unfortunately, the default behaviour
had to be changed for other reasons in commit b5319bdbd0, so
the new OpenSSL CSPRNG failed to keep its promise.
This commit restores the fork-safety using a different approach.
It replaces the fork count by a fork id, which coincides with
the process id on UNIX-like operating systems and is zero on other
operating systems. It is used to detect when an automatic reseed
after a fork is necessary.
To prevent a future regression, it also adds a test to verify that
the child reseeds after fork.

An attack is simple, if the first CMS_recipientInfo is valid but the
second CMS_recipientInfo is chosen ciphertext. If the second
recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct
encryption key will be replaced by garbage, and the message cannot be
decoded, but if the RSA decryption fails, the correct encryption key is
used and the recipient will not notice the attack.
As a work around for this potential attack the length of the decrypted
key must be equal to the cipher default key length, in case the
certifiate is not given and all recipientInfo are tried out.
The old behaviour can be re-enabled in the CMS code by setting the
CMS_DEBUG_DECRYPT flag.
