- both ARM and ARM_HYP haskell specs are now generated from the same set of files using cpp
- callbacks and platform files are merged into one directory (ARM)
- remove check-arm-hyp.py now that there are no ARM_HYP.lhs files
Since we are running with -Werror (maybe we shouldn't) and using cpp to
configure whether arguments are used or not depending on the arch (i.e.
ARM vs ARM_HYP), it makes no sense to make unused variables and imports
an error.
Open to ideas on where to go from here.
The kernel gains an entry point for hypervisor exception events, as well
as a way to add arch-specific handlers for these events.
We do this since the hypervisor has its own entry point into the kernel,
and that must be reflected in the top-level kernel entry interface.
For ARM target, which does not have hypervisor support, we add an no-op stub.
- replace ARM-specific constants and types with aliases which can be
instantiated separately for each architecture.
- expand lib with lemmas used in X64 proofs.
- simplify some proofs.

Hypervisor extensions add extra fault types which are entirely
arch-specific. While the concept of a VM fault exists on all platforms,
these faults are also arch-specific.
This change adds an ArchFault datatype and constructor to the generic
Faults and Failures, and moves VMFault into ArchFault for the ARM
platform.
NOTE: fault indices have changed (generic goes before arch) as per
the changes needed for SELFOUR-413, which is the seL4 C equivalent of
this commit.
* add arch faults and failures to SEL4.cabal
* introduce and handle IRQReserved
On ARM this does nothing, but on other platforms reserved IRQs are
actually used.
* split TCB into ArchTCB (userContext)
* changing ArchFault to make haskell-translator to work
