[RFC][PATCH 05/10] Sparse: fix some "symbol not declared" warnings (Part 3)

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

This commit removes this warning, in various ways, for three more
symbols, thus:

    - 'common_cmds': this symbol is created by the generate-cmdlist.sh
      script, so modify the script to include the static keyword in
      the declaration.

    - 'curl_ftp_no_epsv': add declaration to http.h header file.
      (Note that it could be declared static in http.c, but so could
      several other variables in that header; just being consistent)

    - 'wt_status_use_color': add a declaration to the wt-status.h
      header file, but change the symbol to a function at the same
      time.
