If this module is not being loaded, the kernel will mark any
GRE connection as INVALID in connection tracking, which will
be then silently dropped by a firewall rule.

"** libgnutls: Fixed insecure session ticket key construction, since 3.6.4.
The TLS server would not bind the session ticket encryption key with a
value supplied by the application until the initial key rotation, allowing
attacker to bypass authentication in TLS 1.3 and recover previous
conversations in TLS 1.2 (#1011).
[GNUTLS-SA-2020-06-03, CVSS: high]
** libgnutls: Fixed handling of certificate chain with cross-signed
intermediate CA certificates (#1008).
** libgnutls: Fixed reception of empty session ticket under TLS 1.2 (#997).
** libgnutls: gnutls_x509_crt_print() is enhanced to recognizes commonName
(2.5.4.3), decodes certificate policy OIDs (!1245), and prints Authority
Key Identifier (AKI) properly (#989, #991).
** certtool: PKCS #7 attributes are now printed with symbolic names (!1246).
** libgnutls: Added several improvements on Windows Vista and later releases
(!1257, !1254, !1256). Most notably the system random number generator now
uses Windows BCrypt* API if available (!1255).
** libgnutls: Use accelerated AES-XTS implementation if possible (!1244).
Also both accelerated and non-accelerated implementations check key block
according to FIPS-140-2 IG A.9 (!1233).
** libgnutls: Added support for AES-SIV ciphers (#463).
** libgnutls: Added support for 192-bit AES-GCM cipher (!1267).
** libgnutls: No longer use internal symbols exported from Nettle (!1235)
** API and ABI modifications:
GNUTLS_CIPHER_AES_128_SIV: Added
GNUTLS_CIPHER_AES_256_SIV: Added
GNUTLS_CIPHER_AES_192_GCM: Added
gnutls_pkcs7_print_signature_info: Added"

There is not enough stuff that it is justified to have an own file.
This patch therefore merges everything into general-functions.pl.
There are no functional changes.

IMHO this can be safely disabled, as there is little if any need to debug
userspace programs _that_ deeply on an IPFire machine.

This is dangerous as it allows replacing the running kernel without
rebooting. Kernel Self Protection Project people recommend to keep it
disabled.

In my point of view, the last sentence matches our situation.
