Currently, if set -e spots a nonzero exit we basically have
no real debug information- it just stops immediately without stating
where or why. This forces our scripts to be stupidly verbose so
we can track roughly where they were, thus when they fail we can
use that information to localize the rough exit point.
Instead we should be traping that set -e induced exit and
outputing necessary debug information to run it down. This includes
outputing the relevant stack trace, or at least what we can get of
it.
The 'die' function is now enhanced to automatically dump the trace
that lead to it. For most consumers this is desired- however for
commandline parsing induced dies ("--board is missing" for example),
the trace is noise. For those cases, a 'die_notrace' function was
added that retains the original non-backtrace behaviour.
Example output via instrumenting cros_generate_breakpad_symbols
w/ the failing command '/bin/false' (nonzero exit code).
Before:
./cros_generate_breakpad_symbols monkeys --board=x86-alex
<no output at all, just exit code 1>
With this CL:
./cros_generate_breakpad_symbols monkeys --board=x86-alex
ERROR : script called: ./cros_generate_breakpad_symbols 'monkeys' '--board=x86-alex'

A modest number of different scripts and files have a usage
restricted to build_image. Move those files to build_library,
to prevent them accumulating unwanted clients.
