01801b131f selinux: Switch to a more reasonable model for PID and socket files
Instead of restricting PID files to /var/run/passt.pid, which is a
single file and unlikely to be used, use the user_tmp_t type which
should cover any reasonable need.

4902447630 selinux: Define interfaces for libvirt and similar frameworks
Services running passt will commonly need to transition to its
domain, terminate it, connect and write to its socket.

The init_daemon_domain() macro now defines the default transition to
the passt_t domain, using the passt_exec_t type.

9136f74015 selinux/passt.if: Fix typo in passt_read_data interface definition
This is an example interface, currently unused, so it went undetected:
m4 macros need a backtick at the beginning of a block instead of a
single quote.

fb7b71b86f contrib/apparmor: Merge pasta and passt profiles, update rules
AppArmor resolves executable links before profile attachment rules
are evaluated, so, as long as pasta is installed as a link to passt,
there's no way to differentiate the two cases. Merge the two profiles
and leave a TODO note behind, explaining two possible ways forward.

Update the rules so that passt and pasta are actually usable, once
the profile is installed. Most required changes are related to
isolation and sandboxing features.

fedora-review says:

  Note: Directories without known owners:
  /usr/share/selinux/packages/passt, /usr/share/doc/passt,
  /usr/share/selinux, /usr/share/selinux/packages

...which makes it fall under MIT licensing terms. Daniel reports that
it's very unusual for spec files to contain explicit licensing terms

I originally added licensing information using SPDX identifiers to
make the project fully compliant with the REUSE Specification 3.0
(https://reuse.software/spec/), but there are anyway a few more files
not including explicit licensing information. It might be worth to
fix that later on, in any case.

Use an explicit docdir as shown in:

Otherwise, RPM builds for OpenSUSE will fail now that we have a README

41b5ff0a14 fedora: Introduce own rpkg macro for changelog
git_dir_changelog is useful in theory, but it requires pairs of
annotated tags, which should be generated by rpkg itself to make any
sense, implying a relatively heavyweight interaction whenever I want
to push a new package version.

Also, the default content of the changelog entries include the full
list of changes, but the Fedora Packaging Guidelines specifically
mention that:

  [t]hey must never simply contain an entire copy of the source
  CHANGELOG entries.

We don't have a CHANGELOG file, but the full git history is
conceptually equivalent for this purpose, I guess.

Introduce our own passt_git_changelog() rpkg macro, building
changelog entries, using tags in the form DATE-SHA, where DATE
is an ISO 8601 date representation, and SHA is a short (7-digits)
form of the head commit at a given moment (git push).

These changelog entries mention, specifically, changes to the
packaging information itself (entries under contrib/fedora), and
simply report a link to cgit for the ranges between tags.
