    addr_resolv: speed up reading manuf, services, etc.
    
    An unoptimized, Debug+ASAN `tshark --version` takes about 1 second. 17%
    of the cycles are spent in addr_resolv_init and 7% within fgetline. Use
    fgets instead, now fgetline only costs ~0.5% (11% for addr_resolv_init).
    
    This limits the line length to 1K which should more than be sufficient
    for all involved files (longest lines: manuf 154, services 222).
