On the user side, coqtop and coqc take a list of warning names or categories
after -w. No prefix means activate the warning, a "-" prefix means deactivate
it, and "+" means turn the warning into an error. Special categories include
"all", and "default" which contains the warnings enabled by default.
We also provide a vernacular Set Warnings which takes the same flags as argument.
Note that coqc now prints warnings.
The name and category of a warning are printed with the warning itself.
On the developer side, Feedback.msg_warning is still accessible, but the
recommended way to print a warning is in two steps:
1) create it by:
let warn_my_warning =
CWarnings.create ~name:"my-warning" ~category:"my-category"
(fun args -> Pp.strbrk ...)
2) print it by:
warn_my_warning args

I've included some other changes that didn't happen in this PR.

This is a first step to relay location info in an uniform way, as needed
by warnings and other mechanisms.
The location info remains unused for now, but coqtop printing could take
advantage of it if so wished.

It has been accidentaly broken since early 2014 (and especially
in 8.5), no easy repair, I won't devote any more hours to this stuff.
Moreover no one seems to care apart from Emilio, but he's ok to work
on this in a separate repository or branch.
I left a dev/doc/ocamlbuild.txt file with a few words about this
experiment.

functions about interpretation, internalization, externalization of
notations.
Main syntactic changes:
- subst_aconstr_in_glob_constr -> instantiate_notation_constr
(because aconstr has been renamed to notation_constr long time ago)
- extern_symbol -> extern_notation
(because symbol.ml has been renamed to notation.ml long time ago)
- documentation of notations_ops.mli
Main semantic changes:
- Notation_ops.eq_glob_constr which was partial eq disappears: use
glob_constr_eq instead
- In particular, this impacts a change on funind which now use the
(fully implemented) glob_constr_eq
Somehow, instantiate_notation_constr should be in notation_ops.ml for
symmetry with match_notation_constr but it is bit painful to do.

We're back to a unique build phase (as before e372b72), but without
relying on the awkward include-deps-failed-lets-retry feature of make.
Since PMP has made grammar/ self-contained, we could now build
grammar.cma in a rather straightforward way, no need for
a specific sub-call to $(MAKE) for that. The dependencies between
files of grammar/ are stated explicitely, since .d files aren't
fully available initially.
Some Makefile simplifications, for instance remove the CAMLP4DEPS
shell horror. Instead, we generalize the use of two different
filename extensions :
- a .mlp do not need grammar.cma (they are in grammar/ and tools/compat5*.mlp)
- a .ml4 is now always preprocessed with grammar.cma (and q_constr.cmo),
except coqide_main.ml4 and its specific rule
Note that we do not generate .ml4.d anymore (thanks to the .mlp vs.
.ml4 dichotomy)

Coqdep_boot has almost no dependencies, and hence can be compiled
very early during the build, without relying on .ml.d files.
Some code of system.ml is now in a separate file minisys.ml,
which is also included in system.ml for compatibility.

This reverts commit a66b57ba4bba866bb626bde2b6fe3b762347eb3e.

This patch splits pretty printing representation from IO operations.
- `Pp` is kept in charge of the abstract pretty printing representation.
- The `Feedback` module provides interface for doing printing IO.
The patch continues work initiated for 8.5 and has the following effects:
- The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`,
`pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`,
`msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be
used instead.
- Feedback provides different backends to handle output, currently,
`stdout`, `emacs` and CoqIDE backends are provided.
- Clients cannot specify flush policy anymore, thus `pp_flush` et al are
gone.
- `Feedback.feedback` takes an `edit_or_state_id` instead of the old
mix.
Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.

Return the most appropriate evar_map for commands that can run on
non-focused proofs (like Check, Show and debug printers) so that
universes and existentials are printed correctly (they are global
to the proof). The API is backwards compatible.

This is not perfect yet, in particular the whole precedence system is a real
mess, as there is a real need for tidying up the Pptactic implementation.
Nonetheless, printing toplevel values is only used for debugging purposes, where
an ugly display is better than none at all.

An .emacs-ready elisp snippet to parse location of Anomaly backtraces

Some parts of Evarutils were related to the management of evars under constraints.
We put them in the Evardefine file.

When generating the OS X Coq + CoqIDE bundle, hdiutil often produces error
5341. This seems to be a known bug on Apple's side, occurring for some sizes of
dmg files. We try to change the current (problematic) size by adding a file
full of random bits.

We just reuse the same one weird old trick in CAMLP4 to compare keywords and
identifiers as tokens. Note though that the commit 982460743 does not fix the
keyword vs. identifier issue in CAMLP4, so that the corresponding test fails.
This means that since that commit, some code compiling with CAMLP5 does not
when using CAMLP4, making it a second-class citizen.
