[Tarantool-patches] [PATCH 0/2] [draft] fiber: introduce fiber creation backtrace

[Egor Elchinov via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

From: Egor2001 <elchinov.es@gmail.com>

This patchset is a proof-of-concept for the fiber creation backtrace.

For testing convenience, parent backtrace is 
temporarily moved to the separate lua subtable
backtrace_parent of fiber.info.

For now only C backtrace is implemented.
For the Lua parts of backtrace parent lua state 
needs to be somehow introduced to the new fiber.
Proper solution to this issue needs to be discussed.
