bmcdump: ignore dump request when a dump is in progress

At present generating a user dump is an asynchronous call
and does not block the user to generate another dump.

This can cause out-of-memory issues if dumps are
generated in a loop.

Adding a check to see if the user-initiated dump is
already in progress before starting another user
dump request.

Return "Unavailable" error if generate user dump request is
received while a user dump generation is in progress.

Tested:
'''

/xyz/openbmc_project/dump/bmc xyz.openbmc_project.Dump.Create CreateDump a{sv} 0

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
