Tyson Nottingham d6a70d27c7 Fix false negatives in checkAssignBoolToFloat and minor related improvements (#2198) 
* Fix false negatives in checkAssignBoolToFloat

Detect assignments to expressions involving pointer dereferences, array
element accesses, etc.

* Pass assignment token to assignBoolToFloatError

Pass assignment token rather than boolean token to make error reporting
consistent between checkAssignBoolToFloat and checkAssignBoolToPointer,
as well as with other assignment checks in the code base.

* Make checkAssignBoolToPointer check consistent with checkAssignBoolToFloat

Rikard Falkeborn 007b5d3e8d Fix #9343 (memleak FP when return with cast) (#2162) 
This was most likely introduced when the checks were changed to run on
the full tokenlist instead of the simplified one.

Take care to warn about cases where casts destroy the pointer, such as

	uint8_t f() {
		void* x = malloc(1);
		return (uint8_t)x;
	}

.travis.yml: Run addon tests also with Python 3 (#2185) 
Python 3 does not search parent directories of the initially executed
script for modules imported by modules in this parent directory by
default. So simply set the PYTHONPATH to the ./addons directory. Thus
all scripts are found. It is similar to running the test-*.py script
from the ./addons directory, but this way all the paths in the test-*.py
scripts do not have to be changed (for example to find the cppcheck
executable.
For more details regarding the parent directory issue see for example:
https://stackoverflow.com/questions/11393492/python-package-import-from-parent-directory
For details about the used PYTHONPATH solution see:
