This used to hold a pair of pointers to the previous and next function
segment
that belong to this function call. Replace with a pair of indices into
the
vector of function segments.

gdb/ChangeLog:
* btrace.c (ftrace_fixup_caller, ftrace_new_return,
ftrace_connect_bfun,
ftrace_bridge_gap): Replace references to btrace_thread_info::segment
with btrace_thread_info::next_segment and
btrace_thread_info::prev_segment.
* btrace.h: Remove struct btrace_func_link.
(struct btrace_function): Replace pair of function segment pointers
with pair of indices.
* python/py-record-btrace.c (btpy_call_prev_sibling,
btpy_call_next_sibling): Replace references to
btrace_thread_info::segment with btrace_thread_info::next_segment and
btrace_thread_info::prev_segment.
* record-btrace.c (record_btrace_frame_this_id): Same.
