Add code for supporting -p option mainly

1. include\bcsniffer.h:
1) Align protocol macros to header.
2) Refactor typedef union _node to _option_value, and add Boolean
print_data to it.
3) Move enum Trur_False to include\common.h
2. include\common.h
1) Move enum Trur_False from include\bcsniffer.h to include\common.h
2) Refactor struct pkg_lit name to struct node name and add
s_port/d_port to it.
3. include\listop.h
1) Align function statement to lib\data_struct_lib\listop.c.
4. include\printmsg.h
1) Align function statement to lib\display_lib\printmsg.c.
5. lib\common_lib\common.c
1) Just format.
6. lib\data_struct_lib\listop.c
1) Add two new include headers for tcphdr and udphdr.
2) Add new function: search_and_add_node. It would encapsulate the calls
to
search_node_in_list, sum_package_amount_in_list and add_node_to_list.
Originally, the
functionalities were put in src\bcsniffer.c. That's cumbersome.
3) In order to distinguish port per protocol and stat them, I appended
more
arguments to almost functions in listop.c and added more code to process
different
protocols and ports.
7. lib\display_lib\printmsg.c
1) Add code for deal with print port.
8. lib\netop_lib\netop.c
1) Few small changes.
9. src\bcsniffer.c
1) Refactor some variables.
2) Add code to process command line option -p for port.
3) Remove code whose responsibilities are set default value for opts,
which are
redundant.
10. Remove all #ifdef DEBUG and debug print sentences and format code.
