Pawel Wodkowski 848daf274b log: add backtrace option ...

Add '--enable-log-bt=lvl' option to show simple backtrace in following
form:

thread.c: 346:spdk_io_device_register: *ERROR*: io_device 0xf2ef80
already registered
*ERROR*: === BACKTRACE START ===
*ERROR*:   1: spdk_io_device_register() at 0x6d64df
*ERROR*:   2:  spdk_copy_engine_initialize() at 0x71059c
*ERROR*:   3:   spdk_copy_engine_subsystem_initialize() at 0x572ed0
*ERROR*:   4:    spdk_subsystem_init_next() at 0x6ca756
*ERROR*:   5:     spdk_subsystem_verify() at 0x6caba7
*ERROR*:   6:      _spdk_event_queue_run_batch() at 0x6c1ffa
*ERROR*:   7:       _spdk_reactor_run() at 0x6c5349
*ERROR*:   8:        spdk_reactors_start() at 0x6c784f
*ERROR*:   9:         spdk_app_start() at 0x6bf18e
*ERROR*: === BACKTRACE END ===

This adds additional libunwind dependency so don't enable by default.
