From: Egor Elchinov <elchinov.es at gmail.com>

This patchset adds the subtable `backtrace_parent()`
to `fiber.info()` holding backtraces of fiber
creation and introduces `fiber.parent_bt_enable()`
and `fiber.parent_bt_disable()` procedures managing
the runtime ability to collect parent backtraces for
newly created fibers.

Changes in v2:
 - first 3 patches merged together
 - unnecessary changes in `ENABLE_BACKTRACE` usages reverted
