Ragel still produces a wrong state machine if `const char *` is used
for characters representation that are actually utf8.
This PR changes all types to `unsigned char *` for consistency.
This pattern often surfaces in spam (frequently advance fee fraud)
disseminated via compromised accounts, adding it to ABUSE_FROM_INJECTOR
to increase the likelihood of such spam getting rejected.
Signing of ARC-Seal headers was recently broken; the created signatures
failed to validate. Most likely, this was caused by commit 1e661a2fc6,
which changed the way signatures are created in lua_rsa_sign_memory
without adding the calls to EVP_PKEY_CTX_set_rsa_padding and
EVP_PKEY_CTX_set_signature_md needed with the new interface.
After fixing this, some existing tests failed, because the test values
passed to the hash parameter did not have the correct size for a sha256
hash. I fixed these by adjusting the length of the test values.
Additionally, I extended the "RSA sign" unit test to compare the created
signature against the expected one. This is possible because RSA signing
is deterministic, and should prevent the same bug from occuring again.

It seems that on aarch64 Linux char is signed by default, so Ragel produces
a wrong code that is "optimized" by a compiler simply to `false`.
Issue: #5172
The keylen variable used in lua_ucl_newindex function should use size_t
type instead of lua_Integer, because all functions that use keylen
expect it to be of size_t type. This mismatch leads to incompatible
pointer types, and modern versions of GCC fail to compile the code.
