Subject: [PATCH] templates: require the protocol name to start with a capital

When running ./setup-app-layer.sh require the protocol name to
start with a capital letter so it looks somewhat like a proper
name. This will help give better function names.

For example:

   ./setup-app-layer.sh IRC
   ./setup-app-layer.sh Irc

will create function names starting with IRC or Irc. But we do
not want function names to start with "irc".
