This is a partial backtrack on
63cfc77ddf3586262d905dc351b58669d185a55e. In that commit, we
disregarded exception and tried to print error messages just by
listening to feedback.
However, feedback error messages are not always emitted due to
https://coq.inria.fr/bugs/show_bug.cgi?id=5479
Thus meanwhile it is safer to go back to printing the information
present in exceptions until we tweak the STM.
This fixes https://coq.inria.fr/bugs/show_bug.cgi?id=5467 and many
other glitches not reported, such errors in nested proofs.

Indeed we were not correctly backtracking in the case of
StackOverflow. It makes sense to remove the inner handler which is a
leftover of a previous attempt, and handle interpretation errors in
load as non-recoverable.

Today, both modes are controlled by a single flag, however this is a
bit misleading as is_silent really means "quiet", that is to say `coqc
-q` whereas "verbose" is Coq normal operation.
We also restore proper behavior of goal printing in coqtop on quiet
mode, thanks to @Matafou for the report.

PR #441 and #530 had an interesting interaction creating two bugs:
- #441 stopped emitting feedback for the parser, however #530 changed
the mechanism to print parser errors to the feedback, thus when the
two patches were applied, parsing errors were not printed in
batch_mode.
- Additionally, #530 contains an error: prior to `Stm.init` we must
take care of exceptions `require ()`/etc... otherwise they won't get
printed.

This header file had accumulated quite a bit of cruft over the
years, we clean it up while we are at it.
No functional change as all the removed variables/methods were noops
long time ago.

- We clean-up `Vernac` and make it use the STM API.
- Now functions in `Vernac` for use in the toplevel and compiler take
an starting `Stateid.t`.
- Duplicated `Stm.interp` entry point is removed.
- The XML protocol call `interp` is disabled.

We remove the camlp4 compatibility layer, and try to clean up
most structures. `parsing/compat` is gone.
We added some documentation to the lexer/parser interfaces that are
often obscured by module includes.

We solve https://coq.inria.fr/bugs/show_bug.cgi?id=4789 by printing
all the errors from the feedback handler, even in the case of coqtop.
All error display is handled by a single, uniform path.
There may be some minor discrepancies with 8.6 as we are uniform now
whereas 8.6 tended to print errors in several ways, but our behavior
is a subset of the 8.6 behavior.
We had to make a choice for `-emacs` error output, which used to vary
too. We have chosen to display error messages as:
```
(location info) option \n
(program caret) option \n
MARKER[254]Error: msgMARKER[255]
```

This patch restores the proper printing of anomalies in coqtop / coqc
/ coqide. Currently, they are printed with an `Error` header, whereas
they should be printed with an `Anomaly" header.
This reopens an unfinished debate started in #390 , about how to
properly do "message" headers. Prior to #390, headers were handled
inconsistently, sometimes, `Error` or `Anomaly` were added in
`CErrors`, which lives below of the tagging system, thus some times we
got no coloring (c.f. https://coq.inria.fr/bugs/show_bug.cgi?id=4789),
but some other times the headers were added by the message handlers in
Feedback.
PR #390 takes the position of identifying the messages with the
`Feedback.level` tag, and letting the backends to the tagging. This
makes sense as the backends may want to interpret the "headers" in any
way they'd like. For instance, instead of printing: `Error: foo` they
may want to insert an image.
Note that this implies that CoqIDE doesn't currently insert an error
header on the first error case. This could be easily solved, but for
anomalies we could do in any of the ways explained below.
There are thus two natural ways to handle anomalies here: One is to
tag them as errors, but add a text header, this is done now, with the
small optimization in the case the handled has access to the exception
itself. The second way is to add a new `Feedback.level` category and
tag the anomalies appropriately. We would need also to modify Fail in
this case, or to completely remove it from the protocol.
I guess feedback from the rest of developers is needed before
committing to a strategy, for now this patch should be good.

Previously, tags were associated to terminal styles, which doesn't make
sense on terminal-free pretty printing scenarios.
This commit moves tag interpretation to the toplevel terminal handling
module `Topfmt`.

For legacy reasons, pretty printing required to provide a "tag"
interpretation function `pp_tag`. However such function was not of much
use as the backends (richpp and terminal) hooked at the `Format.tag`
level.
We thus remove this unused indirection layer and annotate expressions
with their `Format` tags.
This is a step towards moving the last bit of terminal code out of the
core system.

Previously to this patch, Coq featured to distinct logging paths: the
console legacy one, based on `Pp.std_ppcmds` and Ocaml's `Format`
module, and the `Feedback` one, intended to encapsulate message inside a
more general, GUI-based feedback protocol.
This patch removes the legacy logging path and makes feedback
canonical. Thus, the core of Coq has no dependency on console code
anymore.
Additionally, this patch resolves the duplication of "document" formats
present in the same situation. The original console-based printing code
relied on an opaque datatype `std_ppcmds`, (mostly a reification of
`Format`'s format strings) that could be then rendered to the console.
However, the feedback path couldn't reuse this type due to its opaque
nature. The first versions just embedded rending of `std_ppcmds` to a
string, however in 8.5 a new "rich printing" type, `Richpp.richpp` was
introduced.
The idea for this type was to be serializable, however it brought
several problems: it didn't have proper document manipulation
operations, its format was overly verbose and didn't preserve the full
layout, and it still relied on `Format` for generation, making
client-side rendering difficult.
We thus follow the plan outlined in CEP#9, that is to say, we take a
public and refactored version of `std_ppcmds` as the canonical "document
type", and move feedback to be over there. The toplevel now is
implemented as a feedback listener and has ownership of the console.
`richpp` is now IDE-specific, and only used for legacy rendering. It
could go away in future versions. `std_ppcmds` carries strictly more
information and is friendlier to client-side rendering and display
control.
Thus, the new panorama is:
- `Feedback` has become a very module for event dispatching.
- `Pp` contains a target-independent box-based document format.
It also contains the `Format`-based renderer.
- All console access lives in `toplevel`, with console handlers private
to coqtop.
_NOTE_: After this patch, many printing parameters such as printing
width or depth should be set client-side. This works better IMO,
clients don't need to notify Coq about resizing anywmore. Indeed, for
box-based capable backends such as HTML or LaTeX, the UI can directly
render and let the engine perform the word breaking work.
_NOTE_: Many messages could benefit from new features of the output
format, however we have chosen not to alter them to preserve output.
A Future commits will move console tag handling in `Pp_style` to
`toplevel/`, where it logically belongs.
The only change with regards to printing is that the "Error:" header was
added to console output in several different positions, we have removed
some of this duplication, now error messages should be a bit more
consistent.

This reverts 4444768d3f4f9c4fcdd440f7ab902886bd8e2b09
(the mllib dependencies that should be surely tweaked more).
The logic for `fatal_error` has no place in `CErrors`, this is
coqtop-specific code.
What is more, a libobject caller should handle the exception correctly,
I fail to see why the fix was needed on the first place.

We also remove flushing operations `msg_with`, now the flushing
responsibility belong to the owner of the formatter.

This is what has always been used, so it doesn't represent a functional
change.
This is just a preliminary patch, but many more possibilities could be
done wrt tags.

Maxime points out that -notop cannot be used as the kernel requires
all constants to belong into a module. Indeed:
```
$ rlwrap ./bin/coqtop -notop
Coq < Definition foo := True.
Toplevel input, characters 0-23:
> Definition foo := True.
> ^^^^^^^^^^^^^^^^^^^^^^^
Error: No session module started (use -top dir)
Coq < Module M. Definition foo := True. End M.
Module M is defined
Coq < Locate foo.
Constant If you see this, it's a bug.M.foo
(shorter name to refer to it in current context is M.foo)
```
My rationale for the removal is that this kind of incomplete features
are often confusing to newcomers ─ it has happened to me many times ─
as it can be seen for example in #397 .

This commit is essentially moving files around. In particular, the corresponding
plugin still relies on a mllib file rather than a mlpack one. Otherwise, this
causes link-time issues for third-party plugins depending on modules defined
in the Ltac plugin.

Currently, the STM, vernac interpretation, and the toplevel are
intertwined in a mutual dependency that needs to be resolved using
imperative callbacks.
This is problematic for a few reasons, in particular it makes the
interpretation of commands that affect the document quite intricate.
As a first step, we split the `toplevel/` directory into two: "pure"
vernac interpretation is moved to the `vernac/` directory, on which
the STM relies.
Test suite passes, and only one command seems to be disabled with this
approach, "Show Script" which is to my understanding
obsolete. Subsequent commits will fix this and refine some of the
invariants that are not needed anymore.

Types were a bit difficult to read as they were mostly based on
anonymous products, this commit replaces them by named records and
refactors out some imperative code.
There is still quite a bit of room for improvement, but at least the
records provide a basis for more fine-grained understanding and
documentation.

Useful at least for debugging, useful to give a better message than
"this placeholder", even if in the loc is known in this case.
