The declarations in the generated-tracers.h file are
assuming there's only ever going to be one instance
of this header, as they are not namespaced. When we
have one header per event group, if a single source
file needs to include multiple sets of trace events,
the symbols will all clash.
This change thus introduces a '--group NAME' arg to the
'tracetool' program. This will cause all the symbols in
the generated header files to be given a unique namespace.
If no group is given, the group name 'common' is used,
which is suitable for the current usage where there is
only one global trace-events file used for code generation.

SystemTap reserved words sometimes conflict with QEMU variable names.
We escape them to prevent conflicts.
Move escaping into its own function so the next patch can reuse it.

Backends now only contain the essential backend-specific code, and most of the work is moved to frontend code.
