From: Francis Giraldeau <[email protected]>
This patch fixes the association between lttng state dump enum values and the
right lttv state quark.
The patch adds string tables that matches the enums sequence in lttng-modules,
to convert enum value in the state dump to quark.
Update :
* static inline replaces macro
* more specific function name ltt_enum_quark
* move static string tables to state.c
* copy corresponding state dump enum from lttng-modules
* remove strings duplication in module_init
* revert double state change
