* Force-flush log output so we don't lose log output in certain error cases.
* Slow down exit paths: add sleep to die(), wait until last moment to
kill child processes (including the awk log output filter)

we are xtrace happy, however that's just generating bulk in log
files that are mostly ignorable. For the basically bullet proof
functions we should not xtrace.

Move shared and non-DevStack-specific functions to `functions-common`. This is
a code move only with some updated comments. The functions are now
sorted alphabetically within function groups, eg. all git-related functions
are grouped together. The groups are listed at the top of the file.
'functions' sources 'functions-common' so no additional changes are required
for backward-compatability.
All functions shared with Grenade have also been moved.
functions-common was created from commit e0ed8ea038299952826b27a16753775472f108d8
