analyzer: implement kf_strcat [PR105899]
gcc/analyzer/ChangeLog:
PR analyzer/105899
* call-details.cc
(call_details::check_for_null_terminated_string_arg): Split into
overloads, one taking just an arg_idx, the other a new
"include_terminator" param.
* call-details.h: Likewise.
* kf.cc (class kf_strcat): New.
(kf_strcpy::impl_call_pre): Update for change to
check_for_null_terminated_string_arg.
(register_known_functions): Register kf_strcat.
* region-model.cc
(region_model::check_for_null_terminated_string_arg): Split into
overloads, one taking just an arg_idx, the other a new
"include_terminator" param. When returning an svalue, handle
"include_terminator" being false by subtracting one.
* region-model.h
(region_model::check_for_null_terminated_string_arg): Split into
overloads, one taking just an arg_idx, the other a new
"include_terminator" param.
