inets: Add customize option
Many HTTP headers are optional, and it could be desirable for the server to filter and maybe even alter them without replacing the mod_* modules that generate/process them. Add new behaviour httpd_custom_api with default implementation in httpd_custom.erl. Add behaviour module in 18 as then we can specify optional callbacks.
