    lib: add base64 decoder
    
    It became necessary to decode base64 data retrieved from VPD and
    convert it into binary for inclusion in the device tree.
    
    The patch introduces the decoder function based on the description
    found in http://en.wikipedia.org/wiki/Base64.
    
    An open source implementation from http://base64.sourceforge.net was
    considered, in the end the only thing borrowed from it is the table to
    translate base64 ascii characters into numbers in 0..63 range.
    
    BRANCH=none
    BUG=chromium:450169
    
    TEST=created a test harness generating random contents of random size
         (in 8 to 32766 bytes range), then converting the contents into
         base64 using the Linux utility, and then converting it back to
         binary using this function and comparing the results.
    
         It succeeded 1700 iterations before it was stopped.
