Summary:
It can be useful when debugging infer or the Makefiles themselves to see what
`make` is doing. Instead of editing Makefiles to remove `@` now you can `make
VERBOSE=1`.
This is just `git ls-files | grep -e Makefile -e '.*\.make' | xargs sed -e 's/^\t@/\t$(QUIET)/' -i`, and adding the definition of `QUIET` to Makefile.config.

Summary:
This makes sure that one can run `./build-infer.sh` then `make`. Otherwise it's
not always clear what one should do to recompile infer, eg when `make` will
work and when `./build-infer.sh` should be used instead, in particular when the
user doesn't have opam configured for her terminal.

Summary:
This is helpful to make sure tests are up to date wrt the models.
Also made the Java deps depend on the models.jar instead of the model sources
as that's what the tests will be using. In particular, updating the sources of
the models will not update the results of a test unless someone rebuilds
models.jar, so rerunning the tests when the models haven't been rebuilt is
useless.

Summary:
The Java models for resources are way to complex. The main issue I am facing with these models is that small changes in the analysis can affect the generation of the models in some weird ways. For instance, I get different specs for some of the models between my devserver and my devvm, which seems to be mostly related with the backend treatment of `instanceof`.
The objective here is to simplify the models as much as possible in order to:
1) make debugging regressions easier
2) get simpler specs and less modeled methods shipped in `models.jar`

Summary:
Hardcoding `variable@` in Makefiles is Bad™ because it prevents the users from
overwriting them easily with `make variable="my custom value"`. The right way
to do it is thus:
```
variable = variable@
# then use $(variable) everywhere
```
This diff puts all the `variable = variable@` lines in Makefile.config.in, and
changes every occurrence of a `variable@` to `$(variable)` everywhere else.
I mostly automated generating this diff. Here are the steps I did:
- find out which `variable@`s we use:
find . -name 'Makefile*' -exec grep -e '@[^@ []\+@' -o -h \{\} \+ | sort | uniq > config_variables
- write this `replace.sh` script to replace every `variable@` with `$(variable)`:
```
#!/bin/sh
config_vars_file=$1
shift
for line in $(cat $config_vars_file); do
var=$(echo $line | tr -d @)
sed -i -e "s/$line/\$($var)/g" $@ > /dev/null
done
```
- run the script as such:
find . -name 'Makefile.*in' \( -not -wholename './Makefile.config.in' \) -exec ./replace.sh config_variables \{\} \+
- put all the `VARIABLE = VARIABLE@` lines in Makefile.config.in
- move all `Makefile.in` to `Makefile`, since they don't need to be generated by `./configure` anymore:
```
for i in $(find . -name 'Makefile.*in' \( -not -wholename './Makefile.config.in' \)); do \
rm $(dirname $i)/$(basename $i .in) && git mv $i $(dirname $i)/$(basename $i .in) ; \
done
```
- delete all Makefile except Makefile.config from configure.ac
- manually inspect and remove remaining instances of `VAR = $(VAR)` in makefiles, looking at the output of `git grep '^\(\w\+\) = $(\1)'`

The code:
DataInputStream in = new DataInputStream(new BufferedInputStream(new FileInputStream(file)));
creates a resource with `FileInputStream()` and wraps it twice as a field of `BufferedInputStream` and then as a field of `DataInputStream`. Then calling:
in.close();
needs to go down the wrappers hierachy: `DataInputStream.close()` -> `FilterInputStream.close()` which then calls `BufferedInputStream.close()` -> `FilterInputStream.close()` -> `FileInputStream.close()`.
Going down the wrapper was not working before because `FilterInputStream.close()` was only going further when the type of field `in` was `FileInputStream` wheras it should also continue when the type of the field is any subtype of `FilterInputStream`, e.g. `DataInputStream` and `BufferedInputStream` like in the test example. This diff fixes this last aspect.

The case when a resource leaks is reported because the the resource was not closed on the execution branch created by the preconditions checks are not very interesting in practice because the exceptions thrown, either `NullPointerException` or `IllegalStateException` are very rarely caught anyway. So the legimate use of preconditions checks is creating spurious resource leak reports.
