Jeff Lucovsky 5b97f4040c detect/base64: Use Rust defined modes everywhere 
Issue: 6487

To avoid ambiguity, a single definition for base 64 decoding modes will
be used. The Rust base64 transform contains the definitions for the
existing mode types: Strict, RFC2045, RFC4648

Philippe Antoine c272a646c5 detect: SigMatchAppendSMToList can fail 
Ticket: #6104

And failures should be handled to say that the rule failed to load

Reverts the fix by 299ee6ed55
that was simple, but not complete (memory leak),
to have this bigger API change which simplifies code.

Shivani Bhardwaj dad52f133d base64: add new mode as per RFC 4648 
As per RFC 4648,
Implementations MUST reject the encoded data if it contains characters
outside the base alphabet when interpreting base-encoded data, unless
the specification referring to this document explicitly states
otherwise.

Add a new mode BASE64_MODE_RFC4648, and handle input strictly as per the
specification.

Shivani Bhardwaj 5b27619778 base64: make decoder handle decoded data space constraints 
So far, it was the job of caller to send the bae64 decoder a perfect
block of data and take care of the destination buffer (decoded data)
size. Now, make it the decoder's job to take care of any space
constraints that the destination buffer may have and return accordingly.

Also, handle space characters in base64 encoded data as per RFC 2045.

Update MIME parser accordingly to handle the base64 data.

ThreadCtxDoInit will try to allocate it,
ending in out of memory
