    Enable type-checking of arguments passed to printf() et al. · dad25049
    Sandrine Bailleux authored
    This patch modifies the declarations of the functions printf() et al.
    and adds the right GCC attribute to request the compiler to check
    the type of the arguments passed to these functions against the given
    format string. This will ensure that the compiler outputs warning
    messages like the following whenever it detects an inconsistency:
    
     file.c:42: warning: format ‘%d’ expects type ‘int’, but argument 3 has type ‘long int’
    
    It also fixes the type mismatch inconsistencies that it revealed
    across the code base.
    
    NOTE: THIS PATCH MAY FORCE PLATFORM PORTS OR SP/SPDS THAT USE THE
    PRINTF FAMILY OF FUNCTIONS TO FIX ANY TYPE MISMATCH INCONSISTENCIES.
