This deletes much of the old proof code. Basically everything but the minimal necessary infra-structure for producing unsat cores. That includes dependency tracking in preprocessing, the prop engine proof and the unsat core computation code in the old proof manager. These should also go once we fully integrate into master the new proof infrastructure.
It also cleans interfaces that were using old-proof-code-specific constructs (such as LemmaProofRecipe). When possible or when it made sense standalone local proof production code was kept, but deactivated (such is in the equality engine and in the arithmetic solver).

Fixes all -Wshadow warnings and enables the -Wshadow compile flag globally.

This commit adds support for code generation of options with modes (enums). From now on option enums can be specified in the corresponding *.toml files without the need of extra code. All option enums are now in the options namespace.

* [DRAT] ClausalBitvectorProof
Created a class, `ClausalBitvectorProof`, which represents a bitvector
proof of UNSAT using an underlying clausal technique (DRAT, LRAT, etc)
It fits into the `BitvectorProof` class hierarchy like this:
```
BitvectorProof
/ \
/ \
ClausalBitvectorProof ResolutionBitvectorProof
```
This change is a painful one because all of the following BV subsystems
referenced ResolutionBitvectorProof (subsequently RBVP) or
BitvectorProof (subsequently BVP):
* CnfStream
* SatSolver (specifically the BvSatSolver)
* CnfProof
* TheoryProof
* TheoryBV
* Both bitblasters
And in particular, ResolutionBitvectorProof, the CnfStream, and the
SatSolvers were tightly coupled.
This means that references to and interactions with (R)BVP were
pervasive.
Nevertheless, an SMT developer must persist.
The change summary:
* Create a subclass of BVP, called ClausalBitvectorProof, which has
most methods stubbed out.
* Make a some modifications to BVP and ResolutionBitvectorProof as the
natural division of labor between the different classes becomes
clear.
* Go through all the components in the first list and try to figure
out which kind of BVP they should **actually** be interacting with,
and how. Make tweaks accordingly.
* Add a hook from CryptoMinisat which pipes the produced DRAT proof
into the new ClausalBitvectorProof.
* Add a debug statement to ClausalBitvectorProof which parses and
prints that DRAT proof, for testing purposes.
Test:
* `make check` to verify that we didn't break any old stuff, including
lazy BB, and eager BB when using bvminisat.
* `cvc4 --dump-proofs --bv-sat-solver=cryptominisat --bitblast=eager
-d bv::clausal test/regress/regress0/bv/ackermann2.smt2`, and see that
1. It crashed with "Unimplemented"
2. Right before that it prints out the (textual) DRAT proof.
* Remove 2 unneeded methods
* Missed a rename
* Typos
Thanks Andres!

* Split BitvectorProof into a sub/superclass
The superclass contains general printing knowledge.
The subclass contains CNF or Resolution-specific knowledge.
* Renames & code moves
* Nits cleaned in prep for PR
* Moved CNF-proof from ResolutionBitVectorProof to BitVectorProof
Since DRAT BV proofs will also contain a CNF-proof, the CNF proof should
be stored in `BitVectorProof`.
* Unique pointers, comments, and code movement.
Adjusted the distribution of code between BVP and RBVP.
Notably, put the CNF proof in BVP because it isn't
resolution-specific.
Added comments to the headers of both files -- mostly BVP.
Changed two owned pointers into unique_ptr.
BVP's pointer to a CNF proof
RBVP's pointer to a resolution proof
BVP: `BitVectorProof`
RBVP: `ResolutionBitVectorProof`
* clang-format
* Undo manual copyright modification
* s/superclass/base class/

* make LFSCBitVectorProof::printOwnedSort public
* Andres's Comments
Mostly cleaning up (or trying to clean up) includes.
* Cleaned up one header cycle
However, this only allowed me to move the forward-decl, not eliminate
it, because there were actually two underlying include cycles that the
forward-decl solved.
* Added single _s to header gaurds
* Fix Class name in debug output
