Callstack should show reason when symbols cannot be provided #216
Description
Bug Description:
The symbols for the LTTng-UST cyg profile analysis sometimes cannot be provided as some information is missing (vpid, vtid missing), binary not found, etc...
Trace Compass should show somewhere why it is the case and should point to the documentation on how to resolve that issue.
Additional Information
The issue most often is the UstDebugInfoBinaryAspect cannot provide the BinaryCallsite for different reasons. The reason is not escalated and null is returned.
