asprintf() has the problem that it leaves *strp undefined when it
fails. Here is a simple wrapper that ensures NULL if asprintf() fails,
which is much more convenient to use.
This will be useful in future patches, where one needs to return error
messages from maybe failing functions, and more.

Adds a safe strtol helper function, modeled loosely after Wayland
scanner's strtouint. This encapsulates the various quirks of strtol
behavior, and streamlines the interface to just handling base-10 numbers
with a simple true/false error indicator and a uint32_t return by
reference.
Test cases are loosely derived from an earlier patch by Imran Zaman.
