mod_firewall: Initialize compiled chunk just once for all handlers
This should fix a case where some stateful dependencies (such as throttles)
produce separate instances for every call to new_handler(), leading to
surprising behaviour (e.g. rules executed via JUMP CHAIN vs ::deliver would
have separate rate limits).
This also adds better error handling in case the compiled code fails to run
for some reason.

Introduction ============ This module allows to load/unload external components after they have been added/removed to a configuration file. It is necessary to explicitly initiate a reload on Prosody either via prosodyctl reload or config:reload(). Example 1: -------- If Prosody has started with this configuration file: ``` {.lua} VirtualHost "example.com" authentication = "internal_plain" Component "a.example.com" component_secret = "a" Component "b.example.com" component_secret = "b" ``` And the file has changed manually or dynamically to: ``` {.lua} VirtualHost "example.com" authentication = "internal_plain" Component "a.example.com" component_secret = "a" Component "c.example.com" component_secret = "c" ``` Then, the following actions will occur if this module is loaded: 1. The component c.example.com will be loaded and start bouncing for authentication. 2. The component b.example.com will be unloaded and deactivated. The connection with it will not be closed, but no further actions will be executed on Prosody. Example 2: -------- If Prosody has started with this configuration file: ``` {.lua} VirtualHost "example.com" authentication = "internal_plain" Component "a.example.com" component_secret = "a" ``` And the file has changed manually or dynamically to: ``` {.lua} VirtualHost "example.com" authentication = "internal_plain" Component "a.example.com" component_secret = "a" VirtualHost "newexample.com" authentication = "internal_plain" Component "a.newexample.com" component_secret = "a" ``` Then, the following actions will occur if this module is loaded: 1. The component a.newexample.com will be loaded and start bouncing for authentication. Note that its respective VirtualHost is not loaded. Bad things may happen. Usage ===== Copy the module folder into your Prosody modules directory. Place the module between your enabled modules either into the global or a vhost section. No configuration directives are needed Info ==== - 0.9, works
