mod_http_xep227: Add support for import via APIs rather than direct store manipulation
In particular this transitions PEP nodes and data to be imported via mod_pep's
APIs, fixing issues with importing at runtime while PEP data may already be
live in RAM.
Next obvious candidate for this approach is rosters, so clients get immediate
roster pushes and other special handling (such as emitting subscribes to reach
the desired subscription state).

16 First, download and add the module to `module_enabled`. Then you can |
| 1842 | 17 decide on what policy you want to have. |
| 18 | |
| 19 Requiring ciphers with forward secrecy is the most simple to set up. | |
| 20 | |
| 21 ``` lua | |
| 22 tls_policy = "FS" -- allow only ciphers that enable forward secrecy | |
| 23 ``` | |
| 24 | |
| 25 A more complicated example: | |
| 26 | |
| 27 ``` lua | |
| 28 tls_policy = { | |
| 29 c2s = { | |
| 30 encryption = "AES"; -- Require AES (or AESGCM) encryption | |
| 31 protocol = "TLSv1.2"; -- and TLSv1.2 | |
| 32 bits = 128; -- and at least 128 bits (FIXME: remember what this meant) | |
| 33 } | |
| 34 s2s = { | |
| 35 cipher = "AESGCM"; -- Require AESGCM ciphers | |
| 36 protocol = "TLSv1.[12]"; -- and TLSv1.1 or 1.2 | |
| 37 authentication = "RSA"; -- with RSA authentication | |
| 38 }; | |
| 39 } | |
| 40 ``` | |
| 41 | |
| 42 # Compatibility | |

| 44 Requires LuaSec 0.5 | |
