[PATCH] Propagate record_print_flags

[Simon Marchi <simon dot marchi at ericsson dot com>]

These flags are returned as an int by get_call_history_modifiers, and
get cast back to record_print_flags in the btrace code.  Instead, we can
make the arguments of that type from start to end.

gdb/ChangeLog:

	* record.c (get_call_history_modifiers): Return a
	record_print_flags.
	(cmd_record_call_history): Adjust.
	* record-btrace.c (record_btrace_call_history): Adjust.
	(record_btrace_call_history_range): Adjust.
	(record_btrace_call_history_from): Adjust.
	* target-debug.h (target_debug_print_record_print_flags): New.
	* target-delegates.c: Re-generate.
	* target.c (target_call_history): Change flags type.
	(target_call_history_from): Likewise.
	(target_call_history_range): Likewise.
	* target.h (struct target_ops) <target_call_history>: Likewise.
	(target_call_history_from): Likewise.
	(target_call_history_range): Likewise.
