config, btrace: check for pt_insn_event in libipt
Version 2 of libipt adds an event system to instruction flow decoders and
deprecates indicating events via flags in struct pt_insn. Add configuration
checks to determine which version we have.
gdb/
* configure.ac: Check for pt_insn_event, struct pt_insn.enabled,
and struct pt_insn.resynced.
* configure: Regenerated.
* config.in: Regenerated.
