refactor duplicated code in builtin-send-pack.c and transport.c

Browse Source 
The following functions are (almost) identical:

  verify_remote_names
  update_tracking_ref
  refs_pushed
  print_push_status

Move common versions of these functions to transport.c and rename
them, as suggested by Jeff King and Junio C Hamano.

These functions have been removed entirely from builtin-send-pack.c,
since they are only used internally by print_push_status():

  print_ref_status
  status_abbrev
  print_ok_ref_status
  print_one_push_status

Also, move #define SUMMARY_WIDTH to transport.h and rename it
TRANSPORT_SUMMARY_WIDTH as it is used in builtin-fetch.c and
transport.c
