[PATCH 1/4] git-instaweb: Extract configuring web server into configure_httpd

[Jakub Narebski <jnareb@gmail.com>]

This is preparatory work for making start/restart check that
git-instaweb set up correct configuration, and generate it if it is
missing.

Pure refactoring, no functional changes.

As usual, you can check this change with

  $ git blame -w --date=short -C -C HEAD^.. -- git-instaweb.sh |
    grep -C 3 -e '^[^^]' | less -S

assuming that it is checked out (HEAD == this commit).

Thanks Junio for the tip!


Nb. it would be nice to have an option to 'git diff' which would
function like '-w' but ignore code movement...
