Subject: [PATCH] utils: rename base64_{encode,decode}

When statically linking with gnutls, we get definition clash error for
base64_encode which is also defined by gnutls.

/home/rahul.bedarkar/buildroot/output/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libgnutls.a(base64.o): In function `base64_encode':
base64.c:(.text+0x148): multiple definition of `base64_encode'
utils.o:utils.c:(.text+0x4378): first defined here
collect2: error: ld returned 1 exit status

To prevent definition clash, rename base64_{encode,decode}
