Subject: Various changes with focus to startup speedup The startup timeout on
 Win32 is reduced to 80% without assembler and to 50% with assembler usage
 (which is optional) proto.c  - do not look up in filed tree and inserts in
 two steps but do it at once  - next few small speedups  - some often called
 elementary functions can be optionally implemented in assembler  - dispart
 some functions to see more exact result from profiling packet-tpnc.c  - do
 not reallocate memory for each filed
