Draw connection between conjugate wp in the literature and our
exs_valid definition.
Add exs_valid_alt lemma, which is one of the main rules that is
different between wp and conjugate wp (or vs and).

- pull base-level empty_fail lemmas from AInvs into Monads.Empty_Fail
- apply consistent naming
- apply consistent [intro!, wp]
- make all non-conditional lemmas [simp]
- re-add context building to empty_fail rules, because the select_*
rules may need context to solve their side condition

- merge EmptyFailLib into Monads.Empty_Fail
- group Empty_Fail lemmas so it is clear where to add new ones
- add [empty_fail] so not every lemma has to declare multiple attributes
- add instructions

- apply modern style
- contract some proofs
- this commit includes some lemmas factored out from NonDetMonadVCG in
a previous commit

- style and some proof contraction
- `in_monad` set remains unchanged for now (could now add additional
lemmas, but they might break things)

- factor out valid_NF definition and lemmas into NonDetMonad_Total
- apply modern style and (very) occasional proof contraction in both
Signed-off-by: Gerwin Klein <gerwin.klein@proofcraft.systems>
- factor out valid_exs definition and properties into NonDetMonad_Sat
- apply modern style to both of these and More_NonDetMonadVCG
- factor out one lemma into Monad_Lib
- better grouping of lemmas in NonDetMonadVCG
- occasional proof contraction
Should contain no real semantic differences, but might have subtle
wp set changes due to reordering (to be fixed up in a later commit).

This should allow wpfix to automatically fix up projl/projr proofs.
This was previously not possible without drawing in Lib, but will now
be picked up by Lib since theLeft/theRight are now abbreviations.

Split up the material in NonDetMonadVCG into In_Monad, Det, Empty_Fail,
No_Fail, and No_Throw. Most of these can run concurrently and not all
applications need to include all of the material.

During the work on verifying the MCS kernel, many definitions
and rules were added to lib. This commit collects all of these,
with style improvements and some proof improvements.
In particular, this adds several results to deal with while loops,
such as corres_whileLoop

The projection operators should be definitions so that they are stable
under simp and case splits. This enables later projection stacks to
use abbreviations that remain stable.

- make None_Some_strg available generically in LevityCatch
- move word lemmas up into Word_Lib
- move wp lemmas up into lib + minor lib cleanup

While we do want to break up full OptionMonad terms in assumptions, we
do not usually want to break up projections.

wp rules for most operators such as return, get, gets are named
return_wp, get_wp, etc. Then when, whenE, unless, unlessE operators had
an additional hoare_.. prefix that this commit removes for more
consistency.

Moving `Monad_Equations.thy` and `More_NonDetMonadVCG.thy` into Monads
session enables us to remove the Lib and CLib session dependencies in
AutoCorres.
