base 64 encode/decode test

[Chad Yates]

Here is the test program I promised.  On my win32 system and vc++ 6.0 the
second two tests (testPadding1Short, testPadding2Short) fail unless I change
part of the b64Decode function like so:

if (c == '=')
{
  if (bits & 0x40000)
  {
    if (dstsize < 2) break;
    *(pdst++) = (bits >> 10);  // changed from '(bits >> 16)'
    *(pdst++) = (bits >> 2) & 0xff;  // changed from '(bits >> 8) & 0xff'
    break;
  }
  if (bits & 0x1000 && dstsize)
    *(pdst++) = (bits >> 4);  // changed from '(bits >> 10)'
  break;
}

What I want to know if this is system specific (endian related?) or an
actual bug.

thanks,

Chad
