[git commit] httpd: code shrink

[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=535a509846be5087ddd0d6e8fc6399f919942639
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

Use decode_base64() from uuencode.c when uudecode/base64 applets are included.
That function is bigger than httpd's decodeBase64(), so we use the old one when
those applets are disabled. Bloat-o-meter when one of those is enabled:

function                                             old     new   delta
handle_incoming_and_exit                            2371    2265    -106
