If a variable is initialized in a loop body or an if clause or a switch
clause, declare it inside the loop body/clause, and de-initialize it
before leaving the loop body/clause.
De-initialize the gnutls_pkcs12_t before leaving rsa_load_pkcs12(), so
as not to leak it.
Always leave the per-bag loop by "goto done", even if we're not within
an inner loop, to make it clearer what we're doing.
We initialize the bag structure at the beginning of that loop body;
de-initialize it at the end.
If we leave the loop without a private key, and we don't have an error
message, the error is "we didn't find a PKCS8 key"; report that.

Ensure that rsa_load_pem_key() and rsa_load_pkcs12() always return an
error message string if they fail, so that
1) they don't return NULL without supplying an error string;
2) they don't supply an error string if they succeed.
If either of them fails, report the error; if there's no error string,
report an unknown error (that shouldn't happen, but the wsutil/rsa.c
code needs more cleanup before I'll believe it can't happen).
While we're at it, clean up some of those error strings, return NULL
rather than 0 as the failure case from rsa_load_pkcs12() as we do in
rsa_load_pem_key() (they mean the same thing, but NULL makes it a bit
clearer), and de-initialize the private key structure in
rsa_load_pem_key() if we fail (so that we don't leak memory).

Loading PEM and PKCS#11 keys was being done in static functions
in packet-ssl-utils.c. These were moved to wsutil, with prototypes
in a new <wsutil/rsa.h> header. This adds gnutls as optional
dependency to wsutil.
The RSA decryption helper was also moved and is now provided in
<wsutil/wsgcrypt.h>.
This allows more dissectors to access this functionality.
