scripts: add option to start an interactive debug shell

Add an option that, when a command fails:
- starts an interactive shell with the failed command's environment
- attempts re-execution of the failed command, continues, or aborts
at user's whim.

Before starting the debug-shell, the backtrace is printed.
When exiting for an abort, the standard error message is printed.

     3 -= BEGIN original header =-

     4 ARMV5 can use STRD and LDRD access instructions but these accesses need to be

     5 8 byte aligned. The dynamic linker's malloc needs to match this so structures

     6 become 8 byte aligned to void unaligned accesses.
