OpenPOWER: Add support for OpenPOWER dump policy

Add support for system dump policy, here system dump
referes to all OpenPOWER dumps, since all dumps from
host subsystems on OpenPOWER systems are known as system dumps.
Currently supported policy is dump enable. The dump will be
created only if the policy is enabled, if the dump is not
enabled, a dump disabled error will be returned.

If the settings service is not available, considering as
dump is enabled.

Tests:
- Create a dump with policy enabled
busctl --verbose call xyz.openbmc_project.Settings /xyz/openbmc_project/dump/system_dump_policy org.freedesktop.DBus.Properties Get ss "xyz.openbmc_project.Object.Enable" "Enabled"
MESSAGE "v" {
        VARIANT "b" {
                BOOLEAN true;
        };
};

busctl --verbose call xyz.openbmc_project.Dump.Manager /xyz/openbmc_project/dump/resource  xyz.openbmc_project.Dump.Create CreateDump a{sv} 2 "com.ibm.Dump.Create.CreateParameters.VSPString" s "vsp" "com.ibm.Dump.Create.CreateParameters.Password" s "password"
MESSAGE "o" {
        OBJECT_PATH "/xyz/openbmc_project/dump/resource/entry/1";
};

Result: Dump created

- Create a dump with policy disabled
busctl --verbose call xyz.openbmc_project.Settings /xyz/openbmc_project/dump/system_dump_policy org.freedesktop.DBus.Properties Get ss "xyz.openbmc_project.Object.Enable" "Enabled"
MESSAGE "v" {
        VARIANT "b" {
                BOOLEAN false;
        };
};

busctl --verbose call xyz.openbmc_project.Dump.Manager /xyz/openbmc_project/dump/resource  xyz.openbmc_project.Dump.Create CreateDump a{sv} 2 "com.ibm.Dump.Create.CreateParameters.VSPString" s "vsp" "com.ibm.Dump.Create.CreateParameters.Password" s "password"
Call failed: Dump is disabled on this system.

Result: Dump is not allowed

phosphor-debug-collector

Phosphor Debug Collector provides mechanisms to collect various log files and system parameters. Used to troubleshoot problems in OpenBMC based systems.

One such mechanism is dreport, a script that collects debug data and packages it into an archive file.

To Build

To build this package with meson, do the following steps:

    1. meson builddir
    2. ninja -C builddir

To clean the built files run ninja -C builddir clean.

To run unit tests

Tests can be run in the CI docker container, refer local-ci-build

or with an OpenBMC x86 sdk(see below for x86 steps).

meson -Dtests=enabled build
ninja -C build test
