per-OEM kbuild based on memory requirement.

Add a circular buffer to hold roaming related debug log information
for peer and vdev operations in the driver. Purpose is to dump
this information after host or target crash. 256 entries will go
back much deeper into history than dmesg or wlan driver logs found
in crashScope. Information is dumped out as error messages from
crash detection points as necessary.
The support routines help to store the debug logs and dump them,
typically after peer related timeout or assert.
wlan_roam_next_debug_log_index () - Utility routine to compute next index
wlan_roam_debug_log() - Adds a log entry
wlan_roam_debug_string() - Returns debug log type string
wlan_roam_debug_dump() - Dump all wlan roam debug log records
Add new QDF module ID QDF_MODULE_ID_ROAM_DEBUG.

To aid in debugging memory leaks, and improve the robustness of log
recovery from crash dumps, statically allocate pglog_msg in the global
scope. This allows logs to be inspected even in cases where a crash
came late in the unload process. It also improves log recovery
robustness by removing the possibility of using a NULL pointer offset
under certain memory corruptions scenarios.

For fatal events , driver sends EVENT_WLAN_LOG_COMPLETE
to userspace. But there can be multiple events for each
ring id like connectivity, driver , frimware, wakelock etc.
Cnss diag has to trigger copy of pkt log to /sdcard only for
one bug report, so send ring id in log complete event so
that it can trigger copy for driver ring id.

Currently the config ini "wlanLoggingFEToConsole" specifically talks
about enabling the logs to kmsg for FATAL and ERROR logs.
This cfg.ini item should not be specific to any log level, instead
it should just depict whether logging to console should be enabled
or not. Hence change wlanLoggingFEToConsole to wlanLoggingToConsole.
