This commit applies the new canonical formatting style using `clang-format` with custom settings (notably 4-space indentation), as part of our shift toward automated formatting normalization.
⚠️ No functional changes are included — only whitespace and layout modifications as produced by `clang-format`.
This change is part of the formatting modernization strategy discussed in:
https://github.com/rsyslog/rsyslog/issues/5747
Key context:
- Formatting is now treated as a disposable view, normalized via tooling.
- The `.clang-format` file defines the canonical style.
- A fixup script (`devtools/format-code.sh`) handles remaining edge cases.
- Formatting commits are added to `.git-blame-ignore-revs` to reduce noise.
- Developers remain free to format code however they prefer locally.
also bump default development container to Ubuntu 24.04
This commit also contains some nitfixes that were detected
by the newer CI components. If it is just nitfixes, we do not
create separate commits for them.
The RSYSLOG_DYNNAME used to make test file unique was very long,
which potentially causes issues with some test scenarios.

Also, the dynamic port determination method we currently use
is not 100% reliable. That port number was used inside the DYNNAME
and thus was not necessarily unique. This has now changed to the
current time in microseconds plus a hash of the test file name. This
should be sufficiently unique. If still not, we can now simply
extend the test_id program (e.g. read /dev/urandom).
