Summary:
Infer reads the arguments passed to clang, in particular to filter out some
incompatible clang command-line options. But, infer only understands arguments
in arg files if they are presented one per line. That's usually the case, but
infer itself stores clang arguments from compilation databases all on one line.
This breaks filtering.
This changes the type of compilation database items to a list of arguments, so
that they can be stored one per line when possible.
Also does some cleanup/renamings, and remove trailing `_` from temp file names, eg:
clang_command_.tmp.2b2602.txt -> clang_command.tmp.2b2602.txt
Also, do not escape arguments from arg files when printing them in logs (that
was useless and ugly).

The goal is not to end up with a deep copy when nothing has changed, as this

Summary:
There's no real reason not to use `Core` lists in this module. Changed the
interface to be more `Core`-like. Changed the `*_changed` functions to use a
ref to track changes instead of passing the changed state around.

- InferPrint reports time stats only, logged in `reporting_stats/` as well as a `PerformanceStats` event with `stats_type: reporting`

Summary:
Perf reporting can now be registered at one point (with desired start real and cpu times) and triggered later
- This is accomplished by storing perf file names in a hashtable mapping to the reporting function
- New `stats_kind` parameter that is either Time, Memory, or TimeAndMemory, where Time requires a Unix.process_times and an Mtime_clock.counter to be passed in, but TimeAndMemory just uses the time from the start of the process.

Summary:
At the moment, Java and Clang sources/sinks live in the same inferconfig entry.
If we try to parse a Java procedure that happens to be an invalid Clang qualified name (e.g., `MyClass.<init>`),
parsing will crash.
As a temporary fix, throw an exception and catch it instead.
In the future, we can avoid this by requiring that JSON source/sink specifications to indicate the language.

Summary:
- Rather than passing a directory name to PerfStats reporting api to write the stats to, and then determining the EventLogger `stats_type` from that dirname, there is now a `stats_type` type in PerfStats, and the directory name and EventLogger tag is automatically determined from that type after it is passed to the API
- This allows us to determine whether we're in capture mode or linters mode dynamically from PerfStats itself, and use the appropriate tag when creating an event

Summary:
Aggregate initialization (e.g., `S s{1, 2}`) doesn't invoke a contructor.
Our frontend translates aggregation initialization as assigning to each field in the struct.
To avoid the appearance of the struct being uninitialized, count any assignment to a field of an aggregate struct as initializing the struct.
