catatonit v0.2.0

This is the first patch release of the v0.2.x branch of catatonit. It
includes a single fix which solves an issue users were running into when
running rootless Podman with catatonit as the pause container process.

 * catatonit will now chdir to / in order to avoid keeping the directory
   it was running in busy. This was causing issues with rootless
   Podman's pause container keeping some /home/... paths busy and
   blocking umounts. (#28, #33)

v0.2.0

This release contains no functional changes from catatonit v0.1.7. The
only change is that we have relicensed catatonit from GPL-3.0-or-later
to GPL-2.0-or-later. For most users this license change is immaterial,
but it will allow catatonit to be used in certain deployments where
some of the GPLv3 license terms pose an issue.

v0.1.7

This release adds the ability for catatonit to be used as the only
process in a pause container, by passing the -P flag (in this mode no
subprocess is spawned and thus no signal forwarding is done).

v0.1.6

This release fixes two issues found by @alexlarsson and fixed by @guiseppe:

 * Container-based socket activation support with runc sets LISTEN_PID=1 when
   forwarding socket-activation-related file descriptors, but with catatonit
   this doesn't work because catatonit is pid1 not the actual container
   process. As such, catatonit will now rewrite the LISTEN_PIDS environment
   variable to equal the pid2 pid if LISTEN_PIDS is equal to the pid of
   catatonit.

 * File descriptors passed to the pid2 process were not closed by catatonit
   after starting pid2 which could lead to several negative scenarios (such as
   resources being kept around unnecessarily). Now catatonit will close all >=3
   file descriptors after spawning the child process.

And a miscellaneous issue about a file handle for /dev/tty being leaked to pid2
because O_CLOEXEC wasn't set (in the original Rust version O_CLOEXEC isn't
necessary because that's the default setting for Rust file handles).

v0.1.5

This release fixes two issues that were found by @davidscherer where
catatonit would hang if pid1 died in unexpected ways. Users are
recommended to update.

v0.1.4

This includes support for the "-g" option provided by tini, which is
needed for the Rook project to switch to tini.

v0.1.3

This includes Docker-compatibility where we pretend that we are 'tini'
in order to silence warnings from Docker. No other functional changes.

v0.1.2

This release just includes the cosmetic changes since we're now an
openSUSE project.

This includes a small fix for the libtool requirements to allow building
catatonit on older distributions.

v0.1.0

This is the first release of catatonit. At this point it works fully (to
the best of my ability) and is incredibly simple to use and maintain.
