Summary:
It's easy to create large arrays in code, eg `int x[1UL << 16];`, but
these can generate huge nodes in SIL because zero-initialization is
translated by zero-ing structures element by element. Introduce a
builtin to use instead. Keep the naive method for small structures (with
a configurable limit on "small").

Summary:
Warning: This might be a bit brutal.
PerfStats and EventLogger are pretty much subsumed by `ScubaLogging`.
It seems no one has been looking at the data they generate recently.
Let's delete them! If we need to re-implement some parts later on, let's
do that using `ScubaLogging`, which is better (eg, still produces data
when infer crashes).
Things we lose:
- errors in the clang frontend due to missing decl translation, etc.
- errors in biabduction due to timeouts, functions not found, etc.
We could also re-implement these using BackendStats and ScubaLogging
instead of brutally deleting everything.

Summary:
The `--continue-analysis` option enables continuing analysis after more targets are captured by
`--continue`. For example,
```
$ infer capture -- buck build tgt1
$ infer analyze --merge
$ infer capture --continue -- bucck build tgt2
$ infer analyze --merge --continue-analyze
```
In the last analysis, it reuses the analysis results of `tgt1` from the previous analysis. If
`tgt1` and `tgt2` have a same dependency to a library, the analysis results of the library is also
reused.

Summary:
You should use `--buck-java` instead, which uses the new "genrule
master" integration.
This diff makes it impossible to select the previous integration.
Upcoming diffs will clean up the resulting dead code.
This also make infer fail hard when no buck mode is specified in a buck
capture command, eg `infer -- buck build //foo:foo`. The reason is that
we need to choose between 3 incompatible integrations and making any of
them the default will confuse at least one person in the future.

Summary:
This changes how we select amongst our (currently) 4 Buck integrations
for Java and clang, as well as how the user's choice is reflected by the
Config module.
The old command line interface is still supported but is now deprecated.
The changes in how to select each integration are:
- clang via "flavors", activated with `--flavors`, now with `--buck-clang`
- clang via "compilation DB", activated with `--buck-compilation-database`, unchanged
- Java via "genrule", activated with `--genrule-master-mode`, now with `--buck-java`
- Java "without genrules", used to be activated by *not specifying any other Buck mode*, unchanged
Instead of various `Config` flags corresponding to the previous CLI that
are allowed in any combination of `flavors`,
`buck_compilation_database`, `genrule_master_mode`, `Config` now exposes
a single `buck_mode` datatype. This allows, eg, `flavors` to override
`buck_compilation_database` if needed. It will also make it easier to
get rid of the old "Java without genrules" integration in a later diff
(see inline comments).

Summary:
Sqlite versions set their own default page and cache size. Old versions use crazy-non-optimal settings.
Allow setting both from command line and set up reasonable defaults. See, e.g.,
https://wiki.mozilla.org/Performance/Avoid_SQLite_In_Your_Next_Firefox_Feature
for page size notes.
The defaults will cost a maximum of 64Mb in cache per Infer process. These improve merging times significantly.

Summary:
I found it very confusing that running infer with --debug makes the
report to be different.
Intuitively, I expect (and I think majority of users would expect) that
`--debug` makes things more verbose (and potentially more slow / consuming
more memory and disk space), but does not change anything apart from it.
One pro of preserving existing behavior, pointed by jvillard:
- Suppose some check is experimental or disabled in the config. The
users expect the issue to be found, but it does not show up. They run
`infer --debug` to understand the behavior, and suddenly the issue shows
up.
I, hovewer, find this pro not important enough and potentially confusing
the users even more.
(If they want to investigate seriously, they can always use
--no-filtering, and there are a lot of cases when the issue does not
show up for others, much hard to undertand reasons, than the fact that
it is disabled).

Summary:
These have proved to be too fragile to maintain as they would often break
compilation of user code. They have been off by default for more than a year
now (D7350715).
Removing the include models shows a more accurate picture of what infer results
look like in production. As such, lots of tests have changed, mostly
biabduction but also in inferbo. SIOF was using include-based models too but
now libc++ is better and iostreams are implemented in a way that SIOF
understands (instead of being magical creatures) so nothing changed there.

Summary:
- make most behaviours independent of the java version so that either works fine without user intervention
- modify regexp used to parse `javac` output to work for all versions
- no need to be sure we are in Java 11 to match java 11-only method name in quandary
- for the rest, provide a command-line flag to specify the java version manually in case it differs from the version that infer was built against
- this only affects the Maven integration for now
To do all that, also change the configure script to record the version of java instead of just a boolean for whether it's >= 10.

Summary:
The default values of config options can sometimes depend on build-time
configuration values. This makes checking that the manuals "remain the same"
trickier as the manuals can be different depending on the platform. This
removes *all* default values from the checked-in manuals. We could be more
fine-grained and scrub only the values that are susceptible to change but for
now this is probably good enough.
This is done by implementing new options `--help-scrubbed` and
`--help-scrubbed-full` and using these in our tests instead of `--help` and
`--help-full` (which remain unaffected).
Also don't wrap the default values in `$(i,...)` anymore because the defaults
can trigger line breaks and then the man page is ill-formatted because that
format is stupid.
