tests: robustify signal delivery test against kernel bugs
Recent kernel siginfo changes, namely, v4.14-rc1~60^2^2~1,
v4.16-rc1~159^2~37, and v4.16-rc1~159^2~39, introduced ABI regressions
that render the whole siginfo interface unreliable.

unwind: rename public functions in an object-oriented fashion
This change renames functions exported to strace core part from unwind
subsystem.
The new names imply that unwind subsystem exports two types of
functions. One is for manipulating back-end itself, "unwind_" prefix
is used for this type. Another is for manipulating back-end private data
structure (unwind_ctx) attached to tcb, "unwind_tcb_" is used for this
type.
This naming should help people to understand unwind subsystem

The aim of this change is to introduce an ability to perform multiple
checks for a specific bpf command. In order to achieve so, all the

from data each time before a bpf call.
