Replumbing: re-implement error reporting for providers

The idea is that providers should only have to report a reason code.
The library code is considered to be libcrypto internal, and are
allocated dynamically and automatically for providers on creation.

We reserve the upper 8 bits of the reason code for internal OpenSSL
use.  This allows our own providers to report errors in form of a
packed number that includes library number, function number and
reason number.

With this, a provider can potentially use any reason number it wants
from 1 to 16777216, although the current error semantics really only
allow 1 to 4095 (because only the lower 12 bits are currently
considered an actual reason code by the ERR subsystem).

A provider can provide a reason string table in form of an array of
ERR_STRING_DATA, with each item containing just the reason code and
the associated string, with the dispatch function numbered
OSSL_FUNC_PROVIDER_GET_REASON_STRINGS matching the type
OSSL_provider_get_reason_strings_fn.
If available, libcrypto will call that function on provider
activation.

Add a nid 2 algorithm name mapping capability

Providers that link against libcrypto can just use OBJ_nid2sn() to look
up the name of an algorithm given a NID. However that doesn't work for the
FIPS provider because OBJ_nid2sn() is not available there (due to the
reliance of the code on ASN.1 types). Therefore we provider a new function
to do this mapping. For providers linking against libcrypto the new function
just wraps OBJ_nid2sn(). For the FIPS provider it has a look up for all the

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.

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).

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.
