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.

Event indicating to the user space that the driver has detected an
internal failure. The driver is expected to recover from such a failure
automatically, e.g., by resetting the device.
This event carries the information indicating the reason that triggered
this detection.

wlan_logging_sock_svc has a reference to the vos_ctx. Since this is
obsolete, remove the reference.

The Linux Coding Style enumerates a few special cases where typedefs
are useful, but stresses "NEVER EVER use a typedef unless you can
clearly match one of those rules." The hdd_adapter_t typedef does not
meet any of those criteria, so replace references to it with a
reference to the underlying struct.

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 QDF trace error/fatal log messages are logged using
pr_info and bydefault these logs do not show up on console.
Hence log QDF trace error/fatal log messages using pr_err
such that bydefault these logs show up in console.

Currently logging thread priority is equal to cds
thread which can cause scheduling issues to other
priority tasks when there are too many wlan debug
messages.
Set logging thread priority to default value.

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.

At this point lot of Win code already uses QDF_TRACE macro. It will be
difficult to translate QDF_TRACE to qdf_trace_msg unless all the modules
(already using QDF_TRACE) make changes to use the qdf_print_ctrl
framework. Until that happens, we can have a shared object temporarily
so that wlan_log_to_user and hence user space logging of messages can be
in place
