Bug description: Base64 decoder doesn't ignore all input characters that it should
ignore
Description:
------------
ext/standard/base64.c contains a mapping array called base64_reverse_table
that has 256 elements, but only 240 initializers. This means that input
characters in the range 0xF0 to 0xFF map to 0 (because the compiler fills
the remaining elements) instead of -1 and therefore are not ignored as
they should be.
Here's a diff for the trivial patch:
