for_each_helper tries to calculate a one-past-the-end pointer for its
wl_array input. This is fine when the array has one or more entries, but we
initialize arrays by setting wl_array.data to NULL. Pointer arithmetic is
only defined when both the pointer operand and the result point to the same
allocation, or one-past-the-end of that allocation. As NULL points to no
allocation, no pointer arithmetic can be performed on it, not even adding 0,
even if the result is never dereferenced.
This is caught by clang's ubsan from version 10.
Many tests already hit this case, but I added an explicit test for iterating
over an empty wl_map.

Some headers and source files have been using types such as uint32_t
without explicitly including stdint.h.
Explicitly include stdint.h where appropriate.

It was failing with missing include files.
While here, destroy the ugly "../src/..." include
paths used in the tests that was just hacking around
this problem in the Makefile:
sed -i s/..\\/src\\/// tests/*.c

Wrap all tests with a memory balance check to detect potential
memory leaks.
Fixed a few tests that had memory leaks contained in the tests
themselves.

We use a simple test-runner helper that runs each test in a separate
process and reports the pass/fail rate at the end.
