Summary:
Load proc descs from the "procedures" sqlite table instead of from
file-wide cfgs stored in the "source_files" table. This removes the need
for a cache of these file-wide CFGs, which was needed because loading
them is expensive and potentially needed in case we need to load the
proc descs of several procedures in the same file. Now we can just load
the proc descs one by one and not worry about caching.

Summary:
First step: record the proc desc of each procedure in the "procedures"
table. Update them according to the attributes logic. Bonus: this
proc-desc for a procedure is now always in sync with its attributes.
For now nothing uses these per-procedure cfgs. Later diffs make more and
more use of them and eventually kill off file-wide CFGs from the
database.

Summary:
In a future commit `Attributes` will depend on `Procdesc` and that
creates a cycle for the functions concerned with specialising proc
descs, which need `Attributes`.

Summary:
Before storing attributes to disk, we fix their location information if needed.
Ideally we wouldn't be creating bogus attributes but sometimes the frontends
are built in a way that makes it difficult to do otherwise, thus we have to
live with this. However, what's aggravating is that attributes are also saved
in the proc descs of these procedures but in their wrong version. This makes
the two versions (inside the procedures sqlite table and inside the procdesc in
the cfg of the source_files table) agree.

Summary:
- abstracted the type for a node key
- moved it to its own module with an ugly `compute` to avoid cyclic dependencies...
- renamed `node_id` to `node_id_key` where needed

Summary: C++17 introduce guaranteed copy elision which omits constructor calls. In ownership analysis, we depended on these constructor calls to acquire ownership. In particular, when a method returns struct, previously, a constructor was used to acquire ownership. In this diff, we acquire ownership of the returned structs directly.

Summary:
This diff:
- translates C++ `catch` blocks
- adds an exceptional control-flow edge from the end of a `try` block to the beginning of a `catch` block
This obviously doesn't reflect the way exceptions actually work, but I think it is better than what we have now. For one thing, we'll see/translate code inside `catch` blocks, which were opaque before. If Clang analyses don't want this behavior, they can simply use `ProcCfg.Normal` (which, up until this diff, behaved identically to `ProcCfg.Exceptional`.
In the future, we can extend `trans_state` to track blocks that might throw an exception, and have each of these blocks transition to `catch` instead.

Summary:
Add a `--source-files` option to `infer explore` to print information about the source files captured by infer.
More precisely, `infer explore --source-files` will print each row of the "source_files" table in the results database.
Option `--source-files-filter` can be used to filter output to file names matching an SQLite "LIKE" pattern.
Flags `--source-files-cfgs`, `--source-files-type-environment`, `--source-files-procedure-names` and `--source-files-freshly-captured` control which columns to print.
The printers for some existing types have been tweaked to improve the output.
