Summary:
Add an option for realloc and fiddle with the other options' help for
consistency.
Moved the memory leak test to memory_leak.c and added more.
Moved the place where we take the options into account closer to their
corresponding models to defend a bit against modifying one without
modifying the other.

Summary:
Let's model all the dynamic memory management functions as they all work
together and are important for a lot of C projects.

Summary:
This makes reports more readable: they were all at the end of functions,
currently.
This is actually quite tricky to do as it involves detecting which
locations are unreachable.
Some of this logic can/should probably be shared with
`AbductiveDomain.discard_unreachable` but at the moment that's not the
case.

Summary:
Most/all of the time we expect the history of the value to faithfully
trace how it got allocated. That history was then added as a prefix of
the trace leading to the same place, leading to duplicate information in
the report trace.
We may need to do the same for other bug types.

Summary:
Turns out the mistake was pretty simple: we just forgot to keep the
history of the return value in the callee and add it to the caller's.

Summary:
- Changed "passed as argument to f" to "in call to f", as these do not
always correspond to passing an argument (eg could be a value returned
from f)
- Changed "assigned" to "returned" when appropriate
- Changed the model of malloc() to not say "allocated" in the null case
- Don't print "returned from f" when there was no event inside f: just
print "in call to f".

Summary:
The order was reversed when printing the trace, leading to confusion.
Also make sure we indicate which part of the trace we are printing when
there is more than one part (either context + access or invalidation +
access, or all three).
Also start nesting at <calling context length> to better represent the
role of the calling context visually.

Summary:
There's been regressions in --pulse-isl. Without tests, everything is
temporary!
Note: the regressions are presumably still there, this just records the
current status of pulse.isl.
Also, no objective-C(++) at the moment. Should we add them too? (in
another diff)
