Summary:
We keep track of both `beginPtr` and `endPtr` but the modelling was mostly
about `beginPtr` as some sort of approximation I guess. This shouldn't change
much but will be useful later when doing more iterator stuff.

This will be needed to re-use the functions now in Driver.ml in other contexts

Summary:
Thanks to the logging introduced in D5293334 (or because of, depending on your liking of spam), I noticed that there lots of errors being logged of the form
Couldn't read multilink file '/home/jul/infer/infer/tests/codetoanalyze/cpp/errors/infer-out/attributes/d0/multilink.txt': /home/jul/infer/infer/tests/codetoanalyze/cpp/errors/infer-out/attributes/d0/multilink.txt: No such file or directory
I don't think it makes sense to care about multilink files except when `--merge` is specified.
Also introduced a .mli and self-documented a function.

Summary:
Once the fixed/preexisting/introduced sets have been computed, they endure
further filtering which may decide that more of them are equal. These bugs just
get dropped on the floor. Put these into preexisting as well instead, at least
in the case of the "skip_duplicated_types_on_filenames" filter.

Only one instance will win in the end so it's not useful to double register.
Log when that happens. Currently it happens in the Java tests on

Summary:
This avoids race conditions when two processes or more try to lock a file for
writing. It could be that the process losing the race writes less than the
winner, then we get rubbish at the end of the file. Calling `ftruncate(2)` inside the critical section makes sure the
contents of the file are erased first. The harmful race was observed in
xcodebuild sometimes, as it can call infer on the same file several times in
parallel (!).

Summary:
Now that we can run several inter-procedural analyses at the same time, we should no longer use the function `Reporting.log_error_deprecated` as it logs the errors in the specs table. This specs table is normally used for caching and will be deprecated in favor of having a cache summaries for the callees in the `Ondemand` module (to avoid deserialising a callee more than once within the same process).
This revision just renames the reporting functions.

Summary:
This messes up with the Buck cache: if infer recaptures a file with only trivial changes that shouldn't affect the capture Buck will still believe it has to reanalyze everything that depends on that file if there's non-deterministic data in infer's output.
Re-use the `--buck` flag used by the Java Buck integration for mostly the same purposes. Add a few special cases for the flavours integration (eg: keep capture data).
Change perf stats registration to take `Config.buck_cache_mode` into account instead of relying on each call site to handle that peculiarity correctly. Also, there's no need to create the perf stats directories before calling the registration function since it will do that too.

Summary:
It is not used, so one fewer thing to track inside Python.
Note that Python does pass `--buck` to OCaml infer to make it aware that it is
running from within Buck, and the OCaml code uses that flag to trim infer-out
to only what's strictly necessary (and especially to remove non-deterministic
output that would mess with Buck's cache).

Summary:
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.

Introduce a new option `--no-report` (conversely `--report`) to stop reporting
after the analysis. This is useful to call sub-`infer-analyze` processes with

would only manifest itself when per-procedure parallelism disabled, which
