Summary:
Saw these two types of errors before (but they're hard to reproduce locally) when building the models:
- `ERROR: Zip.Error("/mnt/btrfs/trunk-git-infer-739-1503054473/infer/bin/../lib/java/models.jar", "", "end of central directory not found, not a ZIP file")`. I think this means infer reads a partially-written models jar. We shouldn't try to load this in models mode.
- `install` would complain that the destination already exists. I think this can only happen if there's a race and the file gets created between when install first checks and when it tries to write to it.
This made me realise that the some of the models are computed in C and C++ mode
and we pick one computed spec arbitrarily. That sounds a bit dodgy but at least
now we do so in a non-racy way.

Summary:
Instead of a whitelist and blacklist and default issue types and default
blacklist and filtering, consider a simpler semantics where
1. checkers can be individually turned on or off on the command line
2. most checkers are on by default
3. `--no-filtering` turns all issue types on, but they can then be turned off again by further arguments
This provides a more flexible CLI and is similar to other options in the infer
CLI, where "global" behaviour is generally avoided.
Dynamically created checkers (eg, AL linters) cause some complications in the
implementation but I think the semantics is still clear.
Also change the name of the option to mention "issue types" instead of
"checks", since the latter can be confused with "checkers".

Change the API of `Logging` wrt to writing to files and to the console (see
changes in logging.mli).
Write only to one log file: infer-out/log. Prefix each line with the kind of
warning and the PID of the process emitting it. Writing with `O_APPEND` is
atomic so the file should not get garbled by concurrent writes. To get the
output of a single process, find out which one interests you by looking at
infer-out/log, then `grep ^[<PID>] infer-out/log`.
Introduce 3 log levels for debug output and command-line options to set them
for various categories individually.
Change tons of `"\n"` to `"@\n"` so the `Format` module is aware of newlines
without us having to look through every character of every logged string for
`\n` characters.

- Logging.out now prints to stderr (or to log files as before if set up) and
not stdout. If some information should go on stdout then the user should be
able to rely on it (ie, it's not just some progress message). For now only
the summary of the errors is printed on stdout by default.
- Logging.err* functions are gone. If the error is user-visible, it should be
Logging.stderr, or `failwith`. If not, go to the same log file as other
output, which personally I find much more convenient than having to dig through
2 log files every time I'm looking for some output.
