Summary:
a) An update to build-infer.sh to avoid downloading/building 4.02.3
ocaml compiler when it is already present.
b) Add the ifdef to avoid this error on glibc systems:
clang -c -w libc_basic.c -o libc_basic.o
libc_basic.c:692:12: error: unknown type name '__WAIT_STATUS'
pid_t wait(__WAIT_STATUS stat_loc) {

Summary:
- make sure former options of `./infer/lib/python/infer.py --help`, `./infer/lib/python/infer.py --help -- make`, ... all appear in `infer --help`
- add some options to config.ml and infer.ml to fix missing options
- have `infer --help` output help info for Toplevel + Backend + Clang + Java
- wrap help lines at 80 characters

Summary:
Refactor module Prop disentangling the various normalization functions, and moving them inside a new module Normalize.
There is quite a reshuffling of functions, including some dead code removal, but there should be no computational difference.

Summary:
Add module `Core` in Prop to contain the implementation of a prop as a record. The record is private so that pattern matching is unchanged.
Added new function to set individual fields, enforcing that the type becomes exposed when constructing explicitly.
Added function unsafe_cast_to_normal to mark all the cases where a coercion to a normalized type is used.
This is purely a refactoring diff that only affects types, it should have no runtime consequence.

Attribute.remove was performing an ad hoc form of normalization on

Summary:
This diff lifts the Prop.Attribute module out of Prop. This required
moving several Prop functions that depend on Attribute
(find_arithmetic_problem, deallocate_stack_vars, find_equal_formal_path)
and adding numerous calls to Prop.normalize to fix normal/exposed
mismatches. Also note that the type of Prop.normalize is generalized to
allow calling it on normalized props.

Summary:
Change the Aobjc_null attribute from a family of unary predicates, one
for each Pvar.t * Ident.fieldname list, to a single binary predicate.
This diff should not change behavior except for printing of Aobjc_null
attributes. Also, operations such as free variables, etc. should now
behave correctly with respect to variables occurring in the arguments of
Aobjc_null.

Summary:
Add support for nary predicates, not just unary ones. Many operations
don't make much sense for nullary predicates, and are generally treated
as no-ops. The first argument is treated specially, as the "anchor" of
the predicate application. For example, adding or removing an attribute
uses the anchor to identify the atom to operate on. Also, abstraction
and normalization operations treat the anchor specially.

There is no need to call exp_normalize on the sub-expressions of
arguments to atom_normalize, as it calls exp_normalize on its

Summary:
Simplify the (implementation and) interface of Prop by using the atom
type directly instead of a tuple type that duplicates the fields.
This change does not weaken the type guarantees, while reducing
redundancy between types thereby making future changes easier.

Summary:
Change representation of pure predicate applications to distinguish
between positive and negative literals using the Apred and Anpred
constructors instead of a boolean field.
This representation is more compact, and is uniform with the treatment
of equalities and disequalities. Some code is simpler, but there isn't
much in it.

Summary:
Treat attributes as unary predicates in classical first-order logic.
This diff extends predicates with a polarity and uses classical 2-valued
semantics. This potentially changes the behavior of negating
attributes, which was not previously relied on.

Summary:
Replace disequalities to Attribute expressions with predicate symbol
application pure atomic formulas.
This diff should preserve existing behavior, up to the comparison order
of attribute disequalities versus predicate applications.
