Make DH_check_pub_key() and DH_generate_key() safer yet

We already check for an excessively large P in DH_generate_key(), but not in
DH_check_pub_key(), and none of them check for an excessively large Q.

This change adds all the missing excessive size checks of P and Q.

It's to be noted that behaviours surrounding excessively sized P and Q
differ. DH_check() raises an error on the excessively sized P, but only
sets a flag for the excessively sized Q. This behaviour is mimicked in
DH_check_pub_key().

Stop raising ERR_R_MALLOC_FAILURE in most places

Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called. Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

Add a range check (from SP800-56Ar3) to DH key derivation.

Fixes #14401

Note that this moves the public key check out of DH compute_key() since
key validation does not belong inside this primitive..
The check has been moved to the EVP_PKEY_derive_set_peer() function so that
it generally applies to all exchange operations.. Use EVP_PKEY_derive_set_peer_ex()
to disable this behaviour.

util/mkerr.pl: make it not depend on the function code

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.
