  Log Message:
  -----------
  core: enforce bounds checks on input-derived lengths (#3888)

- transformations: account for base64 4/3 expansion in b64encode
  output length check
- parser/parse_body: validate remaining buffer length before delimiter
  comparison in multipart boundary search
- net/proto_tcp: validate Content-Length value before multiplication
  to prevent integer wraparound
- sipmsgops: enforce header name length limit in sip_to_json
  conversion
- msg_translator: validate total URI length in construct_uri before
  writing components

(cherry picked from commit bd32a79eb38429995e30bf7c3859e3ed5b085c49)
