patch, 3 partsremove static vars from "builtin-rev-list.c"

This patch series removes all static variables from "builtin-rev-list.c" except the usage string.

This cleans up the code and should please Dscho.

It also makes it possible to remove restrictions on using the "sho_bisect_vars" function.

  list-objects: add "void *data" parameter to show functions
  rev-list: remove last static vars used in "show_commit"
  rev-list: add "int bisect_show_flags" in "struct rev_list_info"

PS: Sorry but it looks like the script I used to send this series has some bugs.
First the date in the email are wrong, and then I have to resend this cover letter
