When an X.509 certificate has to be renewed it is helpful to use
the old PKCS#10 certificate request as a template, so that the
distinguishedName (DN), the subjectAlternativeName (SAN) and
a certificate profile name don't have to be typed-in again.
The old public key in the existing certreq is replaced with the
new key and the signature is re-generated using the new private key.
The msCertificateTypeExtension OID (1.3.6.1.4.1.311.20.2) can
be used in a PKCS#10 certificate request to define a certificate
profile. It consists of an UTF8 string.

Rename `encrypt` methods to avoid the following build failure when wolfSSL
is built with --enable-opensslextra:

The content field of type OCTET STRING of a ContentInfo object
with ContentType Data
ContentInfo ::= SEQUENCE {
contentType ContentType,
content
[0] EXPLICIT OCTET STRING OPTIONAL
is optional and can be missing if no data is available
The 5.4.0 update changed the default bignum implementation to what
could explicitly be enabled via `--enable-sp-math-all`. Since this uses
fixed-sized buffers sufficient for key sizes of SP_INT_BITS, with a default
of 4096, modp6144 and modp8192 didn't work anymore (wc_DhGenerateKeyPair()
returned MP_EXPTMOD_E). So we have to adapt the feature checks for this.
To support the larger DH groups we can either increase the buffer size
via `--with-max-rsa-bits` or add `--enable-heapmath` so buffers get
(re-)allocated as needed. We go with the latter for now.
This avoids the use of a variable length array, which should probably
be avoided in general due to potential performance, portability and
security issues (not in this particular case, though).

More of this code was already removed with previous commits.
While versions < 1.1.1 are not officially supported anymore, 1.0.2 might
still be in use because before 3.x that was the latest version with
official FIPS support (OpenSSL apparently also provides extended commercial
support for it).
The old API has been deprecated with OpenSSL 3 and direct access to the
state isn't possible via EVP API. In the future we might just remove this
implementation but we'd probably have to implement EAP-AKA' first, which
uses HMAC-SHA-256 with IKEv2's prf+ construct to derive keys instead
of this weird construct (plus what fips-prf builds around it) that's used
by EAP-AKA.
The HKDF-Expand() function defined in RFC 5869 is basically the same as
IKEv2's prf+(), so we can use the former to implement the latter.
However, we can only support HMAC-based PRFs this way, which should be
fine as others are rarely used.
There is a conflict between atexit() handlers registered by OpenSSL and
some executables (e.g. swanctl or pki) to deinitialize libstrongswan.
Because plugins are usually loaded after atexit() has been called, the
handler registered by OpenSSL will run before our handler. So when the
latter destroys the plugins it's a bad idea to try to access any OpenSSL
objects as they might already be invalid.
