btstack_run_loop_posix: implement poll_data_sources_from_irq

btstack_run_loop_posix: implement execute on main thread

btstack_run_loop_posix: implement trigger exit

remove btstack_run_loop_base.h include from run loop implementations and tests

btstack_run_loop_posix: use run loop base (code)

posix: enumerate timers in in btstack_run_loop_posix_dump_timer

avoid warning for set but unused variables when log_info and log_error are disabled

MISRAC2012-Rule-14.4_d: use while(true) instead of while(1)

linked list/run loop: return true if item/data source/timer was removed

posix: fix warning

posix: assert timer is not already in list (only checks items until it finds correct position)

posix: use monotonic clock as timebase if available

posix: handle time_ms overrun after 49 days

Use BTSTACK_FILE__ without __ prefix (MISRAC2012-Rule-21.1)

run_loop: avoid anonymous union

posix: avoid crash when data source is removed and fd set to -1

btstack_run_loop: don't call btstack_run_loop_remove_timer from platform implementation

tool: add update_filename.py that adds __BTSTACK_FILE__ to every .c file for use with debug output instead of __FILE__

fix warnings related to potential loss of precision for integer conversions

posix: fix compile

posix: cleanup fast FTDI hack
