[NEW-PORT] devel/tevent016: Talloc based event loop library

[kiwi]

Summary

tevent is a simple library that can handle the main event loop for an
application. It supports three kinds of events: timed events, file
descriptors becoming readable or writable and signals.

Talloc is used for memory management, both internally and for private
data provided by users of the library.

You are right, wrong cut and paste. This has been fixed

It would be good if we committed this patch in two steps.

1. First, commit an unmodified copy of devel/tevent as devel/tevent016.
2. Second, update devel/tevent016 to 0.1.6.

This way it is easier to see in the commit log what really changed with the 0.1.6 upgrade.

Also, please add PR: xxx to your commit message referencing the Bugzilla issue for Samba 4.20.

Shouldn't that be talloc>=2.4.2?

We'll need to add a similar variable to devel/tevent. As a separate commit.

This change could be dropped.

Isn't talloc a separate port? This part is probably a copy-paste mistake.
