Print a stack trace for minidump files left behind by a crashing program.
`dump_directory` will be searched for minidump files. Any minidump files found will
have `stackwalk_binary` executed on them, with `symbols_path` passed as an extra
argument.
`stackwalk_binary` should be a path to the minidump-stackwalk binary.
If `stackwalk_binary` is not set, the MINIDUMP_STACKWALK environment variable
will be checked and its value used if it is not empty. If neither is set, then
~/.mozbuild/minidump-stackwalk/minidump-stackwalk will be used.
`symbols_path` should be a path to a directory containing symbols to use for
dump processing. This can either be a path to a directory containing Breakpad-format
symbols, or a URL to a zip file containing a set of symbols.
If `dump_save_path` is set, it should be a path to a directory in which to copy minidump
files for safekeeping after a stack trace has been printed. If not set, the environment
variable MINIDUMP_SAVE_PATH will be checked and its value used if it is not empty.
If `test_name` is set it will be used as the test name in log output. If not set the
filename of the calling function will be used.
If `quiet` is set, no PROCESS-CRASH message will be printed to stdout if a
crash is detected.
If `keep` is set, minidump files will not be removed after processing.
Returns number of minidump files found.
