History
Viktor Dukhovni 0cd9dd703e Improve base64 BIO correctness and error reporting 
Also improve related documentation.

- The BIO_FLAGS_BASE64_NO_NL flag did not behave as advertised, only
  leading and trailing, but not internal, whitespace was supported:

      $ echo 'AA AA' | openssl base64 -A -d | wc -c
      0

- Switching from ignored leading input to valid base64 input misbehaved
  when the length of the skipped input was one more than the length of
  the second and subsequent valid base64 lines in the internal 1k
  buffer:

    $ printf '#foo\n#bar\nA\nAAA\nAAAA\n' | openssl base64 -d | wc -c
    0

- When the underlying BIO is retriable, and a read returns less than
  1k of data, some of the already buffered input lines that could have
  been decoded and returned were retained internally for a retry by the
  caller.  This is somewhat surprising, and the new code decodes as many
  of the buffered lines as possible.  Issue reported by Michał Trojnara.

- After all valid data has been read, the next BIO_read(3) should
  return 0 when the input was all valid or -1 if an error was detected.
  This now occurs in more consistently, but further tests and code
  refactoring may be needed to ensure this always happens.
