- `pid` was being run on the host system and not the target.
 - toybox does not have `pid`, use `pidof` instead.
 - throw an error if more than one pid is matched

The previous code used unzip to get the offsets of the files in
the zip file. This was an estimate, and it turns out to be wrong
in many cases. Replace that with zipinfo -v which gives the exact
offset of the files in the zip.

Also update the tmp files so that they are in a dictionary of their
own by apk, instead of embedded in the offset list.

The CallStack function prints stacks to the log. Unfortunately, our
stack script defaults to arm, so if the data is actually arm64, we'll
do nothing. Modify the script to parse the input trying to determine
the abi before processing the rest of the lines. At the very least,
we'll be able to correctly choose between arm and arm64.

The only downside, is that, the old method could take dumps from different
abis, but no one I know does this.

Some of the map names have spaces in them, but only the ones that look
like:

[anon:atexit handlers]

So allow spaces between a [ and a ].

Instead, set it to None and let the caller handle things.
