Make autoregistration ChaCha64 as preffered WireCrypt plugin

[basid-irk]

Currently, chacha UDR-plugin implement ChaCha and ChaCha64 algoritms (quote from plugins.conf):

Plugin = ChaCha64 {
	Module = $(dir_plugins)/ChaCha
}

If rename shared library of chacha UDR-plugin into chacha64, default WireCrypt plugin will be ChaCha64 and it wil work without record in plugins.conf. After that - change plugins.conf as:

Plugin = ChaCha {
	Module = $(dir_plugins)/ChaCha64
}

What's the point of this?

The traffic encryption plugin is not a UDR.

UDRs are loaded using the plugin of the same name, which implements the IExternalEngine interface. The ChaCha64 traffic encryption plugin implements the IWireCryptPlugin interface.

@sim1984 IIRC, if you want to use ChaCha64, then you need 1) plugins/chacha.dll relative to fbclient.dll, and 2) a plugins.conf with that entry, otherwise you'll not have ChaCha64 support. Renaming it will remove the need for step 2 if you use a different fbclient.dll.

The traffic encryption plugin is not a UDR.

That's just the OP using the wrong term here (the correct term would have been (wirecrypt) plugin). It doesn't change the fact that ChaCha64 currently requires an entry in plugins.conf.
