Summary:
Sometimes in debug mode, the condition set is too big to print in the
log file. This diff limits the maximum number of conditions to print

Summary:
`ANSITerminal` flushes after almost every operation. As a result, there is a
lot of flicker in the task bar. Going through `Format` instead reduces the
flicker.
Also erase end-of-lines when outputting logging stuff to the console. This makes sure the output is not garbled with stuff from the task bar.

Replace the previous outputting of "." and "F" with an actual progress bar and
a multiline display of what procedure each process is currently busy analysing.
Observe:

```
This works by setting up a worker pool (as before) that waits to receive jobs
(not as before: we used to fork for each new job). Unix pipes are used for
communication.
The new worker pool can be used to experiment with other concurrency models,
such as reviving per-procedure-parallelism, or making sure each procedure is
analysed only once.
Perf tests indicate that this version is no slower than the previous one,
either on laptops or devserver: about 3% worse user time but ~40% better system time.
This new version forks <jobs> processes whereas the previous version would
fork `O(number of source files)` times.
`infer -j 1` shows a progress bar that doesn't update timing info (because it
would need a second process to do that).

Summary:
`make doc` will use `jbuilder` (which in turn uses `odoc`) to generate the
documentation for infer's modules. This is useful to browse the APIs of infer
and gives a more discoverable place to host more general documentation about
infer's internals.
Besides the actual plumbing necessary to generate the docs, this diff also
- Moves the various infer/src/*/README.md to index.mld files that make it to the generated docs
- Fixes some doc comments that would anger `ocamldoc`

`IList.map_changed` relies on `take_append`.
The existing code was a `take_rev_append` instead.
Fixed it.
Tests are still passing, we might want to look at callsites and consider a `map_changed_unordered`.

Summary:
Add a `--procedures` option to `infer explore` to print information about the
procedures captured by infer. More precisely, `infer explore --procedures` will
print each row of the "procedures" table in the results database. A new
`--procedures-filter` controls which procedures to print information about, and
there is one flag per column in the db too to print more or less options about
each procedure (in particular, we can now print attributes), with some defaults.

Summary:
There's actually a nice separation between IR/, base/, istd/, and the rest of
infer, so they can be made into separate jbuilder libraries so that the
separation remains. This helps make sense of the infer codebase.
Also:
- move everything biabduction-related out of backend/ and into a new
biabduction/ directory. This clarifies the current situation where backend/
contains a mix of analysis-independent code (still there now), and
biabduction-specific code (moved to biabduction/).
- move everything from base/ that is not infer-specific into istd/, e.g. IList.ml
- kill unused `FbTraceCalls`
- A couple of files needed to move around to complete the separation of base/ and IR/
