trace: portable simple trace backend using glib
Convert the simple trace backend to glib so that it works under Windows.We cannot use pthread directly but glib provides portable abstractions.Also use glib atomics instead of newish gcc builtins which may not be...
trace: separate trace event control and query routines from the simple backend
Generalize the 'st_print_trace_events' and 'st_change_trace_event_state' intobackend-specific 'trace_print_events' and 'trace_event_set_state' (respectively)in the "trace/control.h" file....
trace: add "-trace events" argument to control initial state
The "-trace events" argument can be used to provide a file with a list of traceevent names that will be enabled prior to starting execution, thus providingearly tracing.
This saves the user from manually toggling event states through the monitor...
trace: [stderr] add support for dynamically enabling/disabling events

trace: avoid conditional code compilation during option parsing
A default implementation for backend-specific routines is provided in"trace/default.c", which backends can override by setting "trace_default=no" in"configure".
