[Tarantool-patches] [PATCH v3 00/10] fix say_x format and rework fibers

[Cyrill Gorcunov via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

We've been notified that if tarantool instance is running for
long time slice the logger start to print weird lines such as

 | main/-244760339/cartridge.failover.task I> Instance state changed

where fiber's ID represented as a negative number. Eventually we
discovered a few issues

 - a bunch of say_x called with wrong specificators but compiler
   simply ignored it
 - fiber IDs are wrapping and this is inconvenient
 - CFORMAT simply doesn't work

In the series we fix all these issues. Note that using simplified
form for unsigned arguments such as

	"%llu", (long long)(uint64_t)

is pretty fine becase signed/unsiged values are counterpart of
each other guaranteed by standart.
