Instead of using the collection of suppress warnings annotations to filter out the errors while generating the error reports, we just add this SuppressWarnings at translation time, like any other annotations, and the reporting functions in the Reporting module will just skip the errors when the method is annotated with SuppressWarnings.
This allows us to have a suppress warnings mechanism that is independant from the integration with the build system.

Revamped Timeout module by storing elapsed wallclock seconds, and the status of symops, in case of recursive calls.
Extended the API with suspend() and resume() to pause and resume the current timeout.
These are used before and after an on-demand call to the analysis functions.
This achieves the effect that each procedure, even though is interrupted, has its own time and symop counters, which are suspended and resumed as required.

I have seen enough comments in this space by people during code review to switch on the analyses the compiler can already do. This diff is an automated renaming of unused identifiers to _, with a few additional changes made when reading the diff of the results for things that stood out as particularly strange. This base-lines all of the existing warnings. I'm not sure this is a good idea, since it might be better for those familiar with each part of the code to look at these warnings and use them as pointers to suspicious code.

In the case of Java, the name of the method is enough to lookup the summary of the callees and run the symbolic execution. This revision separates the case of method call in Java and in C, C++ and Objective C. Most of the code for executing method calls was Clang specific and this is an intermediate step to be able to run the capture and analysis on demand.

When reading from static fields, the translation was overwriting the list of class members with the list of static ones. The backend was only looking up fields from the list of non static fields.

While playing with the type environment for Java, I realised that the types in models.jar where not re-generated when modifying Infer. As a consequence, some changes in Infer where surprisingly having no effect. This diff forces the type environment to be absent when analyzing the models.

Summary:

Infer would previously give confusing reports in the following case: two classes `foo.MyClass` defined in `MyClass.java` under directory `foo/` and `bar.MyClass` defined in file `MyClass.java` under `bar/` are compiled together in a single call to the Java compiler. Then the errors in `foo/MyClass.java` could potentially be reported in `bar/MyClass.java`, or the other way around.
The reason is: Infer starts the translation from the bytecode which only contains information about the base filename in the metadata. For example, both `foo.MyClass` and `bar.MyClass` will contains the information that the source file is `MyClass.java` but not the full path to the actual source file (hopefully).
In order to cope with this issue, this diff adds the possibility to read the package declaration from the source file so that we can map classes to the source files these classes are defined without ambiguity. In order to avoid having to open and read the source files when not necessary, the code will behave as before as long as no name conflict is found. Otherwise, it will only load and search for the package declaration when two or more sources files have the same basename but are defined in different subdirectories.

modules are better for namespacing.
How I made this diff:
1. moved list_* functions from utils.ml{,i} to iList.ml{,i}
2. shell commands:
grep '^val ' infer/src/backend/iList.mli | cut -f 2 -d ' ' | tr '\n' ' '
# gives a list of former list_ functions that IList implements, fed into the loops below:
LISTNAMES=" compare equal append combine exists filter flatten flatten_options find fold_left fold_left2 for_all for_all2 hd iter iter2 length fold_right map mem nth partition rev rev_append rev_map sort split stable_sort tl drop_first drop_last rev_with_acc remove_duplicates remove_irrelevant_duplicates merge_sorted_nodup intersect mem_assoc assoc map2 to_string"
# replace " list_*" function calls with IList.* ones
for i in $LISTNAMES; do find . -name '*.ml' -exec sed -i -e "s/ list_$i\b/ IList.$i/g" \{\} \; ; done
# replace (list_* functions with (IList.* ones
for i in $LISTNAMES; do find . -name '*.ml' -exec sed -i -e "s/(list_$i\b/(IList.$i/g" \{\} \; ; done
# ditto with [
for i in $LISTNAMES; do find . -name '*.ml' -exec sed -i -e "s/\[list_$i\b/[IList.$i/g" \{\} \; ; done
3. Then fix up the rest by hand. In particular, stuff that called Utils.list_*
explicitely, and stuff that used the "Fail" exception that has moved to
IList. (may revisit this in the future)
