[PATCH 4/9] unwind: rename public functions object-oriented

[Masatake YAMATO]

This change renames functions exported to strace core part from unwind
subsystem.

The new names implies unwind subsystem exports two types of functions.
One is for manipulating back-end itself. "unwind_" prefix is for this type.
The another is for manipulating back-end private data structure (unwind_ctx)
attached to tcb. "unwind_tcb_" is for this type.

The name helps people understand unwind subsystem and the relation between
unwind subsystem and back-ends.

* defs.h (unwind_tcb_print): is renamed from `unwind_print_stacktrace'.
(unwind_tcb_capture): is renamed from `unwind_capture_stacktrace`.
* unwind.c: Ditto.
* syscall.c (syscall_entering_trace): Use the new names.
(syscall_exiting_trace): Ditto.
