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.
