Summary:
Found the dead code with the script in the next commit, iteratively until no
warnings remained.
Methodology:
1. I kept pretty-printers for values, which can be useful to use from infer's REPL (or
when printf-debugging infer in general)
2. I kept functions that formed some consistent API (but not often, so YMMV), for instance if it looked like `Set.S`, or if it provides utility functions for stuff in development (mostly the procname dispatcher functions)
3. I tried not to lose comments associated with values no longer exported: if the value is commented in the .mli and not the .ml, I moved the comment
4. Some comments needed updating (not claiming I caught all of those)
5. Sometimes I rewrote the comments a bit when I noticed mis-attached comments

Summary:
Conversion and reformat of infer source using ocamlformat
auto-formatting tool.
Current status:
- Because Reason does not handle docstrings, the output of the
conversion is not 'Warning 50'-clean, meaning that there are
docstrings with ambiguous placement. I'll need to manually fix
them just before landing.

Summary:
This is step further simplify the code to avoid cases where the summary of the procedure being analyzed can exist in two different versions:
# one version is the summary passed as parameter to every checker
# the other is a copy of the summary in the in-memory specs table
This diff implements:
# the analysis always run through the `Ondemand` module (was already the case before)
# the summary of the procedure being analyzed is created at the beginning of the on-demand analysis call
# all the checkers run in sequence, update their respective part of the payload and log errors to the error table
# the summary is store at the end of the on-demand analysis call

Summary:
This is part of the plan to have every checker take a summary as input, and return the updated sumamry as output. Doing so, we can run all the registered checkers in sequence for every method
This diff change the type of `Ondemand.analyze_ondemand` to return the analysis summary.

Summary:
A good first step in order to run multiple checkers together is to prevent the analysis the analysis to side effect on the summaries of the method being analyzed from disk, or the shared specs summary. The idea is that `Ondemand` creates a summary for the procedure being analyzed and only saves the summary once all the checkers have been run. The summary for the caller (i.e. the procedure being analyzed) should never be looked up from disk during the analysis. In other words, the analysis should only ever lookup the summaries of the callees and the proposed solution to enforce this is to have `Ondemand.analyze_proc_name` be the only way to lookup the summary of a procedure.
Another objective is to make sure that the summaries are never saved to disk more than once.

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: Noticed this when I was writing the documentation for the abstract interpretation framework and was curious about why `Ondemand.analyze_proc` needs the type environment. It turns out that the type environment is only used to transform/normalize Infer bi-abduction specs before storing them to disk, but this can be done elsewhere. Doing this normalization elsewhere simplifies the on-demand API, which is a win for all of its clients.

Summary:
The global reference `DB.current_source` is used internally in the module DB, by all the front-ends, and directly and indirectly by the back-end, including saving and restoring the state in case of on-demand procedure calls. In particular, it is heavily used in printing functions.
This diff cleans up the flow of information about what the current file is, making it explicit, and removes the reference.

In order to implement the lazy dynamic dispatch algorithm, we need to generate a procedure description based on the types encountered during the symbolic execution.

- Always tear down the logging at the end.
- Fix printing of stats to include only the files actually analyzed with --reactive.
- In the progress bar, print F for files and . for procedures.
Example outputs:

Or F without dots if a file was modified but no procedure was.
