Summary:
Add an extra argument everywhere we report about the identity of the
checker doing the reporting. This isn't type safe in any way, i.e. a
checker can masquerade as another. But, hopefully it's enough to ensure
checker writers (and diff reviewers) have a chance to reflect on what
issue type they are reporting.

Summary:
`ProcData.t` contains a `Summary.t`. Eventually we want to fix this too
so that checkers don't depend on backend/, i.e. on all the other
checkers via Summary.ml. But in order to migrate progressively we can
first migrate absint/ and one step on the way is for it to not know what
kind of analysis data it is passing around.
This extra flexibility only costs us passing an extra `Procdesc.t` in a
couple more functions so it's actually not a bad change in itself.

Summary:
This is a step in disentangling the various analyses: that file used to
make every checker on biabduction because of a few of its functions that
use biabduction datatypes.
Split reporting.ml into:
- Reporting.ml: the functions all checkers need to report errors. This
is put in absint/ with the other files that are needed by all
checkers.
- SummaryReporting.ml: functions that need to depend on Summary.ml
(useful for later). This is put in backend/ where Summary.ml lives.
- BiabductionReporting.ml: for the biabduction analysis
The rest of the changes are renames to use the appropriate module
amongst the above.

Summary:
The goals are to have all the checker definitions and documentation in one
place (except how to actually run them, since that's not quite the same
concept; for example inferbo is one checker but several analyses depend on its
symbolic execution), and later on to be able to link issues reported by infer
back to the checker that generated them.
This makes apparent that the documentation of our checkers is lacking,
not touching that in this diff.
Not sure if "analysis" would be a better name than "checker" at this
point? For instance "Linters" is one of the checkers, which historically
at least we have not considered to be the case.

Summary:
The big one:
- stop using polymorphic `<>`, `<`, `>`, ..
- add `<>` to `PolyVariantEqual` escape hatch now that `<>` is as taboo as `=`
- Interestingly, there were a lot of uses of `Z.(x < y)`, which although
they seem to use `Z.lt` actually used polymorphic comparison. The actual
comparison infix operators of `Z` are cleverly hidden in `Z.Compare`
instead, which makes them impractical to use...

Summary:
This diff enables parsing and auto-formatting documentation
comments (aka docstrings).
I have looked at this entire diff and manually made some changes to
improve the formatting. In some cases it looked like it would take too
much time, or benefit from someone more familiar with the code doing
it, and I instead disabled auto-formatting docstrings in those files.
Also, there are some source files where the docstrings are invalid,
and some where the structure detected by the parser appears not to
match what was intended. Auto-formatting has been disabled for these
files.

- 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:
`AccessExpression.t` represents array accesses as `ArrayOffset of t * Typ.t * t
list`, i.e. the index is represented by a list of access expressions. This is
not precise enough when indices cannot be represented as such. In fact, in
general any `HilExp.t` can be an array index but this type was an approximation
that was good enough for existing checkers based on HIL.
This diff changes the type of access expressions to be parametric in the type
of array offsets, and uses this to record `HilExp.t` into them when translating
from SIL to HIL.
To accomodate the option of not caring about array offsets
(`include_array_indexes=false`), the type of array offsets is an option type.
