now as well.
Also, both functions will now test if the executable exists and is valid; that
way, load_image()/exec*() can catch many errors without having to create a new
team (or erase the current one - an exec*("my invalid app") might now return
with an error).
The runtime linker now exports a function to test executables that is aware
of the search paths, and will also check user permissions upfront.
