    lib: fix maybe-uninitialized warnings
    
    With -Og, GCC complains:
    
    easy.c:628:7: error: ‘mcode’ may be used uninitialized in this function 
[-Werror=maybe-uninitialized]
    
    ../lib/strcase.h:35:29: error: ‘tok_buf’ may be used uninitialized in this 
function [-Werror=maybe-uninitialized]
    vauth/digest.c:208:9: note: ‘tok_buf’ was declared here
    
    ../lib/strcase.h:35:29: error: ‘tok_buf’ may be used uninitialized in this 
function [-Werror=maybe-uninitialized]
    vauth/digest.c:566:15: note: ‘tok_buf’ was declared here
    
    Fix this by initializing the variables.
