clang-format: re-format for clang-18

clang-format-18 isn't compatible with the clang-format-17 output, so we
need to reformat the code with the latest version. The way clang-18
handles lambda formatting also changed, so we have made changes to the
organization default style format to better handle lambda formatting.

See I5e08687e696dd240402a2780158664b7113def0e for updated style.

Add one second timer to save POST codes to file

A lot of POST codes are sent to BMC from BIC
in a short time.

In BMC, there is an ipmi handler to get POST codes
and upload to dbus property.

The xyz.openbmc_project.State.Boot@.PostCode service
listens the PropertiesChanged signal and saves to POST
codes history file.

The xyz.openbmc_project.State.Boot@.PostCode service
is hanged if there are too many POST codes in a short time.

At this time, the memory usage of dbus-broker increases,
and the out-of-memory(OOM) issue happens.

The processes are killed when OOM happens,
and BMC may reset unexpected.

Test Case:
Check the frequency for post code file getting larger

Use binary serialization instead of JSON

The binary format is much more efficient than JSON in terms of
computational speed and disk space consumption. The former is important
in case the host is sending a constant stream of POST codes.
post-code-manager can fall behind because it takes too long to store
each new POST code on disk, causing D-Bus messages to pile up and
increase memory consumption inside dbus-broker.

Tested:
Rebooted the host a few times and observed that POST code history is
populated normally in Redfish. After upgrading to this change, old POST
code history stored in JSON format is lost, but remains on disk until it
gets overwritten during subsequent host boots.

- Remove singleton PostCodeDataHolder. It only contained a single int

- Simplify D-Bus match construction by using predefined

- Remove unnecessary PostCode members which were just copies of const
strings.
- Refactor some filesystem path construction/handling to simplify code.

Tested:

still populated in Redfish.

Add timestamp to BIOS POST Codes log and DeleteAll interface

Added GetPostCodesWithTimeStamp methods to PostCode interface.
GetPostCodesWithTimeStamp logs timestamp in microseconds since epoch
together with each post code.

Added DeleteAll method to remove existing logs and
reset currentBootCycleIndex to 1.

Tested:
Build with changes in phosphor-dbus-interfaces.
Invoked GetPostCodesWithTimeStamp with busctl and observed expected format:
("US since Epoch":, Post Code)
"1580923291420015": 1,
"1580923291428076": 2,

Invoke DeleteAll and verify GetPostCodes returns no code afterwards,
and CurrentBootiCycleCount is reset to 1.

Cycled host power more than 100 times and observed that CurrentBootCycleCount
increments until it reached MaxBootCycleNum.

Verified GetPostCodes and GetPostCodesWithTimeStamp respond correctly with
index 1 being the most recent boot cycle, CurrentBootCycleCount being
the oldest boot cycle.
