Summary: public
Load and store the inferred attributes on the analysis summaries. The next step is to use the call stack from performance critical methods to expensive methods form the summary payload instead of modifying the attributes.

Summary: public
We should be able to distinguish if a method is annotated with Expensive and has been automatically annotated as calling an expensive method using internally the annotation CallsExpensive in the later case.

This adds the following subtyping rules:
- methods that are not annotated with Expensive cannot be overwritten by a method annotated with Expensive
- methods annotated with PerformanceCritical must be overwitten by method annotated with PerformanceCritical

Just works by running the analysis bottom-up and promoting any method as virtually annotated with `Expensive` whenever one of its callee is annotated with `Expensive`

Summary: public
This is an initial version of the Expensive checker which only report violations on direct calls. The main objective is to setup all the files for this new checker.
The next steps are:
1) run the checker in interprocedural mode
2) Save in the summary of a method foo() the annotation attribute Expensive if a direct callee of foo is annotated with Expensive
3) Check that Expensive is enforced by subtyping, i.e. check that non-expensive method cannot be overwritten by a method annotated with Expensive

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)

Summary:
Added two annotations @TrueOnNull and @FalseOnNull to be used for boolean functions to specify what value is returned when the argument is null.
Added model for TextUtils.isEmpty, which corresponds to the annotation
@TrueOnNull
static boolean isEmpty(@Nullable java.lang.CharSequence s)
Summary:
System.getProperty can return null when the property is not found, and expects a non-null argument.
Add models for Infer and Eradicate to reflect that.
Summary:
Move proc_attributes to a separate module.
Field err_log, in common between proc desc and summary, can now be moved to ProcAttributes without creating cycles of dependencies.
Summary:
There's a lot of overlap between the representation of a proc desc and a spec summary. This diff moves all the data in common to the single record proc_attributes defined in Sil.
This gives a unified way of accessing most of the data carried by a procedure, whether it is contained in a proc desc or a spec. Also, it ensures that there is a single flow of information from proc desc to spec in the back-end, making sure that the information represented stays consistent.
Summary:
Errors arising from overriding methods defined in other files were not reported, because during parallel analysis the clusters did not have access to overridden methods, so could not load their annotation.
Changed cluster generation to add location information for the methods overridden by the procedures defined in the current cluster.
Summary:
The @NonNull annotation, with camel case, can now be used to inform Eradicate that some fields that are not initialized by the constructor can be initialized by other means, e.g. via dependency injection.
Summary:
This is mostly useful to authors of annotation processors and
`javac`-based static analysis tools. The nullable return models
cover these packages pretty comprehensively (with the exception
of the various visitor classes). The non-nullable parameter models
are mostly there to help make the nullable return models more useful,
as some codepaths will pass a nullable object to one of the utility
classes but never actually invoke a method on the nullable object itself.
Summary:
This commit is the result of
`find infer/src -name '*.ml' -or -name '*.mli' -exec ocp-indent -i \{\} \;`
and
`INFER_CHECK_COPYRIGHT=1 InferPrint`
Summary:
In preparation for C++ methods, we need to have type with
class, method, mangled (for overloading?)
1. Change objc method to support it
2. Do some renames to be less confusing
