Summary:
The 2nd iteration of analysis of the Android core implementation did not yield actionable models, so delete those.
Turn on strict-mode reporting by default, when doing starvation analysis (which is disabled by default).

Summary:
New clang in the plugin \o/
Changes that were needed:
- (minor) Some extra AST nodes
- defining a lambda and calling it in the same line (`[&x]() { x = 1; }()`) used to get translated as a call of the literal but now an intermediate variable gets created, which confuses uninit in one test. I added another test to showcase the limitation this is hitting: storing the lambda in a variable then calling it will not get caught by the checker.

Summary: Before this diff, the analysis would only lookup the attributes with the classname appearing in the instruction. However, it would fail to find those attributes for inherited and not overridden methods. With this diff, the attributes are now searched recursively in the super classes.

Summary:
Keep `--analyzer` around for now for integrations that depend on it.
Also deprecate the `--infer-blacklist-path-regex`,
`--checkers-blacklist-path-regex`, etc. in favour of
`--report-blacklist-path-regex` which more accurately represents what these do
as of now.
Rely on the current subcommand instead of the analyzer where needed, as most of
the code already does.

Summary:
Goal of the stack: deprecate the `--analyzer` option in favour of turning
individual features on and off. This option is a mess: some of the options are
now subcommands (compile, capture), others are aliases (infer and checkers),
and they can all be replicated using some straightforward combination of other
options.
This diff: stop using `--analyzer` in tests. It's mostly `checkers` everywhere,
which is already the default. `linters` becomes `--no-capture --linters-only`.
`infer` is supposed to be `checkers` already. `crashcontext` is
`--crashcontext-only`.

Summary: It is common on Android code to recycle the `View` object by nullifying them in the `onDestroy()` or `onDestroyView()` methods. In this case, the outer `Fragment` object structure is preserve while the inner `View` object are set to null for the garbage collect to release the memory. However, if the fields are only set to `null` in the `onDestroy*()` methods, those fields cannot be `null` during the active lifecycle of the `Fragment`, so it is not necessary to annotate those fields with `Nullable`.

This allows infer devs to see the effects their changes have on the infer manuals.
Check in the manuals for each subcommand + the output of `--help-full` to get a

Summary:
We can fill the gaps in the trace now: they correspond to processes waiting on
pipes. This suggests a more efficient protocol would help perf, at least on the
small example I tried. Anyhow, it shows it's useful to trace pipe operations.
Some small gaps remain but they look like they could be explained by rounding errors.

Summary:
The model for `getcwd` assumes the first argument should be non-null when in fact a NULL pointer is legitimate and results in allocation:
> As an extension to the POSIX.1-2001 standard, glibc's getcwd() allocates the buffer dynamically using mal‐
> loc(3) if buf is NULL. In this case, the allocated buffer has the length size unless size is zero, when buf
> is allocated as big as necessary. The caller should free(3) the returned buffer.
I suggest this glibc extension be used for the getcwd model to reduce false positives.
