Summary:
When invoking `./build-infer.sh java`, there is no need to update the facebook-clang-plugins submodule that is done as part of the `autogen.sh` script. The submodule update takes a very long time and can be skipped when building only for java

Summary:
Module CFrontend_utils is a container for two modules: Ast_utils and General_utils.
Instead of opening CFrontend_utils in several places, it is now split into two separate modules CAst_utils and CGeneral_utils, which are now accessed directly.

Summary:
This diff allows to use the linters written in DSL to check for bugs.
Now new checkers can be written directly in the DSL.
The diff also remove some weirdness and simplify the CTL semantics.
For example no need to unwrap a node when evaluating the IN operator.
Also no need to distinguish anymore between stmt and decl in the
semantics of EX and EF.
Moreover, the diff de-couple hard-coded checkers (eg checks on component kit)
from those checkers parsed in the .al files.

Summary:
A domain should not definite its initial state, since distinct users of the domain may want to choose different initial values.
For example, one user might want to bind all of the formals to some special values, and one user might want the initial domain to be an empty map
This diff makes this distinction clear in the types by (a) requiring the initial state to be passed to the abstract interpreter and (b) lifting the requirement that abstract domains define `initial`.

Summary:
For example: `infer --print-logs --stats -- clang -c hello.c`.
The option is not on by default.
This forwards all the output to log files to stdout or stderr as appropriate.
The multiplexing is very crude and can be improved later if needed if
stdout/err is too garbled by concurrent partial writes.

Summary:
Remove the need for a dummy initialization of log files.
The fact that we were not setting log files in some cases doesn't seem to be
relevant so I killed it. I observed no difference in output on simple clang and
javac examples. It will be easy to restore a better version of it in the next
diff if needed.
Also fix an fd leak: when opening new log files, previous ones were not being
flushed and closed (except at exit).

Summary:
Instead of opening new log files each time with non-deterministic names, keep
appending to the same log files. This only removes the randomized part of the
names in the files. In particular, it keeps the name prefixes for, eg, clang
source files.
Also changed most "<executable>/<executable>-out.log" to simply "<executable>/out.log".

Summary: Adding the information that a procedure has been modelled as part of the attributes, during the translation, instead of getting this information from where is the summary loaded from. This is more consistent with the use of the attributes in other parts of the analysis, but is also useful in the context of the lazy dynamic dispatch algorithm where the procedures, including the models, are cloned and reanalyzed with more specialized parameters. The information about whether a procedure is a model must persist when cloning the procedures.

Summary:
When you try to log an error on a procedure P and a summary for P doesn't exist, the error gets quietly dropped on the floor.
But we should fail loudly instead, because this should only happen in the case of a user error.
Got burned by this today; I was trying to log an error on the *caller* of `Integer.parseInt`, but was accidentally logging it to `Integer.parseInt` itself instead.
Since no summary for that method exists, my error wasn't appearing.

Summary:
The two concepts are not negation of each other. The type environment created by the different frontends is not guaranteed to contain a full view of the type hierarchy. In this case, there can be holes preventing Infer to prove that `t <: t'` if the type definition between `t` and `t'` is missing. There are now two functions:
# `is_known_subtype` when the subtyping relation can be proven
# `is_known_not_subtype` when it can be proven that there is no subtyping relation between two types
This diff is intended to make no functional changes but to add functionality to detect cast error angelically, i.e. assuming that the program is probably fine where there is not enough information to prove the cast error.

There's a lot of boilerplate work to be done when adding a new kind of source.
This diff tries to reduce the boilerplate by making a functor do all the work.
The functor:
(1) adds a notion of "footprint kind" to the source
(2) packages the source with a call site
