Subject: [PATCH] Rename base64_encode

base64_encode is already defined in gnutls so rename it as
motion_base64_encode to prevent a definition clash when linking
statically with gnutls

Fixes:
  - http://autobuild.buildroot.org/results/592672b8826f4c731c50d29725da964d876573c4

Applied upstream:
  - https://github.com/Motion-Project/motion/commit/cc3c25527d4bada0fe98a734fa2df29f8d6cf1ad
