Lock access to and modification of the index.json file, to ensure
concurrent addition/removal does not result in lost state. Use a
standard c/storage lockfile, making use of its r/w locking
ability to support concurrent access, only serializing writes.
This is not a very efficient locking scheme around artifact
removal and - especially - addition. I view this as the first
step, establishing any sort of mutual exclusion to prevent state
corruption. Step 2 is to adapt the staged removal work being
done to make image removal require only minimal use of locks,
ensuring it works with artifact addition. This staged addition
means we won't have to hold the lock for the full artifact pull.

When generating Conmon's command line, we read containers.conf to
get log_size_max and used it if the container didn't override it.
However, `podman inspect` only reads from the container's own
config, and ignores containers.conf. Unify the way we determine
maximum log size with a single function and use it for both
inspect and containers.conf, and add a test for this behavior.

Currently WSL uses UTF-16 encoded output by default but is planning
to use UTF-8.
See https://github.com/containers/podman/issues/26527
To get ready for the change we are enforcing UTF-8 encoded output by
setting the environment variable `WSL_UTF8=1` and by updating the
code that transfomed wsl output from UTF-16 to UTF-8.

Given container logs end up in syslog by default, somewhat-clarify that `--syslog` is about podman logs, not container logs.

During my binary size reduce experiments I often switch build tags
around but make binaries does not recompile in these cases.
It is annoying to always do touch cmd/podman/main.go so let's add it to
the SOURCES instead so the Makefile will recompile on changes.

The build tag was added to remove the "golang.org/x/net/trace"
dependency[1]. So let's use that.
With that we reoduce the binary size by 432KB.

Unfortunately on a number of occasions, Podman has been released
officially with a `-dev` suffix in the version number. Assist in
catching this mistake at release time by the addition of a simple
conditional test. Note that it must be positively enabled by a
magic env. var. before executing the system tests.
Also (thanks to @lsm5) update the TMT test to trigger the new
condition for future Fedora releases.

An HTTP response with Content-Type application/json does not need
to be HTML escaped. Doing this causes encoding issues in the Podman
REST API output as seen in the issue:
Fixes#17769
Remove the HTML escaping from Content-Type: application/json responses.
