commit 30b2d073622148d52a68486855cff7c7440f0b85

    Fix compile error with GCC 8 in makefsdata
    
    lwip/lwip/src/apps/http/makefsdata/makefsdata.c:929:56: error: 
‘snprintf’ output may be truncated before the last format character 
[-Werror=format-truncation=]
       snprintf(qualifiedName, sizeof(qualifiedName), "%s/%s", curSubdir, 
filename);
    
    /home/dziegel/lwip/lwip/src/apps/http/makefsdata/makefsdata.c:929:3: note: 
‘snprintf’ output 2 or more bytes (assuming 257) into a destination of size 
256
       snprintf(qualifiedName, sizeof(qualifiedName), "%s/%s", curSubdir, 
filename);
    
    Reduce subdir string length by 3 bytes to make the warning go away. The 
whole file path including directory AND filename is limited to MAX_PATH_LEN - 
so it is reasonable to reserve 3 bytes less for directory - the filename won't 
fit anyway in the remaining 3 bytes.
