Summary:
Utils contains definitions intended to be in the global namespace for
all of the infer code-base, as well as pretty-printing functions, and
assorted utility functions mostly for dealing with files and processes.
This diff changes the module opened into the global namespace to
IStd (Std conflict with extlib), and moves the pretty-printing
definitions from Utils to Pp.

Summary:
Functions related to source files were already namespaced by `source_file_` prefix. Make separate module for them.
In high level it replaces all `source_file_` with `SourceFile.` and then fixes all remaining compilation errors

Summary:
introduce `AttributesTable.load_defined_attributes` which will return proc attributes only if the procedure is defined. In order to not mess up
with existing caching, create another hashmap to store those procdescs.
We need to do that because with reactive capture we no longer can assume that all proc attributes are final before analysis starts

Summary:
1. Always store cpp model source_file with relative path. This will make them cache friendly independent of infer location
2. Distinguish between "relative to project root" and "relative to infer models src"
3. Unify `source_file_from_path` used by java and C frontends into one function. There are no improvements to that logic yet
4. Move `is_cpp_model_file` to use `source_file` instead of `filename`

Summary:
Merging the results directories of targets on buck projects involved creating symbolic links into buck-out.
The bulk of files are .attr files: one per procedure. Creating these links can be a bottleneck, and the merge phase can be slower than the analysis phases on projects with many procedures.
This diff introduces multilinks to speed up merge.
A multilink is a file `multilink.txt` containing a sequence of paths
```
path/to/file1.ext
path/to/file2.ext
...
```
A multilink file is a compact way to represent a link for each entry.
This diff creates a multilink file for each `attributes/dir` directory, instead of one symbolic link for each file.

Summary:
Declared and defined procedure attributes are now saved in different files (hashed_name.decl.attr and hashname.attr).
We always try to load using the filename of defined procedure attributes first,
and fall back to loading the file for declared ones if it does not exist.
The logic for replacing an existing file stays the same, with one extra thing:
when a file for a defined attribute is written, the one for the declared one
is deleted if it exists.
At the end of a capture, either a declared or a defined file exist, but not both.
The reason for this change is that when captures of different subprojects are
merged together, it can happen that a link gets created to a declared attributes
file even though a defined one exists, so the body of the procedure will not be analyzed.
After this diff, both links will be created, and the defined one will be loaded
by the back-end.

Summary:
This diff removes the redundancy in the representation of types where
struct types could be represented either directly using Tstruct or
indirectly using Tvar to refer to the type environment. A consequence
is that it is much harder to construct large type values.

Summary:
When a project defines the same symbol in different files,
the results of the capture will be different depending on
the order in which files are captured.
In particular, if a procedure with the same name is defined in different files,
it will be associated with the last file being captured.
So the results can be different if the files are processed in different order.
In case of parallel capture, this has in effect a non-deterministic behaviour.
This diff defines a canonical file (alphabetically) when a procedure is multiply
defined, so that the procedure is associated to the same file whatever the order.

Summary:
Now that array types record only static - and therefore constant -
lengths, Sil typ and exp no longer need to be mutually recursive.
This diff:
- splits the recursion in the type definitions of typ and exp,
- splits the recursion in the comparison and pretty-printing
functions,
- and then refactors typ into a separate module.
