stacktrace: Provide helpers for common stack trace operations ...
All operations with stack traces are based on struct stack_trace. That's a
horrible construct as the struct is a kitchen sink for input and
output. Quite some usage sites embed it into their own data structures
which creates weird indirections.
There is absolutely no point in doing so. For all use cases a storage array
and the number of valid stack trace entries in the array is sufficient.
Provide helper functions which avoid the struct stack_trace indirection so
the usage sites can be cleaned up.
