Summary:
The global analysis is doing funky stuff directly with `Summary.OnDisk`.
In order to make starvation/ its own dune library this part needs to
either use ondemand or moved elsewhere. Let's do the latter for now to
avoid changing the behaviour in the middle of the refactoring.

Summary:
There is a case where the class name is "A$1$B$2".
In this case, we would correctly say it is an anonymous class, and
return A$1$B as user defined, which is bad: now we can get the outer
class which will be A$1 that will be anonymous again.
This was leading to tricky bugs.
Now, get_user_defined_class name will return something that is indeeed
contains only user defined names.
There is one tricky pathological case left: when the outermost class is
anonymous, which can in theory occur. This might lead to other tricky
bugs, so the follow up will be to rewrite API of JavaClassName.t so that
this case is made clear for the client.
But lets unbreak nullsafe fore now first.

Summary: Build tool wrappers sometimes have issues when their output streams are redirected to those of infer's while one of those streams is read and used in infer. This diff side-steps this problem by always redirecting the stream of interest to a file (which also helps in debugging), while logging the other stream through `Logging.progress`.

## Issue
Commit [068622c](https://github.com/facebook/infer/commit/068622c) renamed the option `test` to be `only-cheap-debug` and also flipped the default value. Therefore, what used to be `--no-test` (i.e., you _do_ want expensive debug information) is now `--no-only-cheap-debug`.
However, [`01-advanced-features.md`](https://github.com/facebook/infer/blob/master/website/docs/01-advanced-features.md) listed the option as `no_test` (with an underscore rather than a hyphen), which I guess got missed when renaming the option/changing the default.
The suggestion to use `--no_test` was recently suggested in [https://github.com/facebook/infer/issues/1252](https://github.com/facebook/infer/issues/1252#issuecomment-618922148), so we should probably remove this, otherwise you get (even if you use the "correct" syntax for an older Infer):
```
$ infer --no-test
/path/to/infer/bin/infer: unknown option '--no-test'.
```
## Description of changes
Given that `only-cheap-debug` now has a default of _false_ (i.e., if you request `-g`/`--debug`, you automatically get `--no-only-cheap-debug`), making the suggestion to users to turn _off_ "no expensive debugging" is not required.
Consequently, this PR removes the recommendation to pass `--no-test`/`--no-only-cheap-debug` in the documentation.

Summary:
- move a few files from checkers/ so that nullsafe can depend on them
- nullsafe depends on a few files in biabduction/ via Errdesc (not the
biabduction analysis itself but some datatypes and functionality):
- when possible, I've moved the individual functions elsewhere, in absint/Decompile.ml
- nullsafe still depends on a function in Errdesc that unfortunately
depends on a bunch of biabduction datatypes like Prop(!) and some
other functionality that for now is embedded in biabduction
(substitution in SIL instructions).

Summary:
This turned into a pretty big refactoring: the
`IntraproceduralAnalysis.t` needs to be passed around through quite a
few functions. These functions usually depended on
tenv/proc_desc/proc_name that are already in the `analysis_data` so
refactored that too (checking that these were indeed the same as in the
`analysis_data` record (using my own eyeballs). Interestingly there is
one place where we actually turn the analysis to other proc descs than
the original one in eradicate.ml so I've added a small comment there.

Summary:
This diff changes way we treat classes w.r.t. to Nullsafe modes when
issuing meta-issues.
Previously, we considered nested class independently of the outer one.
This was leading to a tricky case: when the class is clean but nested
class needs fixing, meta-info told that class can be Nullsafe.
This is counter-intutive and lead to problems when users tried to follow
wrong nullsafe suggestions for this case.
After this diff we:
1. Start calculating meta-issues only on the outermost level. This will simplify
reasoning about nullsafe stats.
2. Aggregate all nested issues counters to corresponding outer-level class.
Among others, CLASS_CAN_BE_NULLSAFE Advice will finally become
actionable in all known cases.

Summary:
That function was testing if a proc is defined (ok) and if so if it also
had no summary. The second check is wrong because it could be that the
function hasn't been analysed yet. We should call "Ondemand" instead.
But, it seems like a weird check so I just deleted it and replaced is
with just the "is defined" check.
Renamed the "is_library" field in typeOrigin to "is_defined" to better
reflect the expectations. While I was at it, inlined record type
definitions in `TypeOrigin.t`. They were already inlined except for 2!
