This patch changes the VEC(char_ptr) fields in uploaded_tp to use
std::vector<char *>. At first, I wanted to creep in more changes, like
using std::string, but it was making the patch too big and less focused,
so I decided to keep it to just that.
It also looks like the strings in those vectors are never free'd. If
so, we can fix that in another patch.
gdb/ChangeLog:
* tracepoint.h (struct uploaded_tp): Initialize fields.
<actions, step_actions, cmd_strings>: Change type to
std::vector<char *>.
* tracepoint.c (get_uploaded_tp): Allocate with new.
(free_uploaded_tps): Free with delete.
(parse_tracepoint_definition): Adjust to std::vector change.
* breakpoint.c (read_uploaded_action): Likewise.
(create_tracepoint_from_upload): Likewise.
* ctf.c (ctf_write_uploaded_tp): Likewise.
(SET_ARRAY_FIELD): Likewise.
* tracefile-tfile.c (tfile_write_uploaded_tp): Likewise.
