Rename Memory exports. 
This update renames many of the declarations exported by
Data.Macaw.Memory so that we have more consistent names.

The majority of the existing names are now exported with DEPRECATION
warnings.  Some of the symbol declarations that were not used by the
Memory datatype have been moved to other modules.

The minor version of macaw-base has been incremented.

8b0c58c661 Make architecture type families injective 
This should cut down on the number of proxies/explicit type arguments
needed when dealing with these types.

Awkwardly, ArchTermStmt isn't injective, because PPC32 and PPC64 happen
to use exactly the same type. We could add an argument to that type and
then all the families could be injective.

d3f19048ce don't double-offset in pretty-printer 
The pretty-printer for Stmts takes a pretty-printer function as an
argument. This used when a Stmt stores an offset from the beginning of a
block can, but we don't have information about that block internally in
the Stmt.

An ArchState Stmt stores an ArchMemAddr, which is independent of the
block it's in. Previously we were treating the ArchMemAddr as an offset
and passing it to the pretty-printer function for offsets; in practice
this means most of them were printed as values about twice as big as
they were supposed to be.

Relocation support; various cleanups. 
This patch adds initial support for relocations in Macaw code
discovery, and adds other refactoring.

* It introduces a SymbolValue constructor to represent references to
  symbols within Macaw.
* The various cases for x86 mov are made explicit after the flexdis refactor
  broke the previous code.  We should now support segment register movs and
  give better error messages when seeing mov with control or debug registers.
* The generic exception operation is replaced with Hlt and UD2 terminal
  x86-specific statements.
* CodeAddrReason is split into FunctionExploreReason and BlockExploreReason to
  clarify whether a function or block was discovered.
* The Macaw pretty printer is changed to use write_mem in place of pointer syntax.
* Various other refactoring is made to clarify code.

2524b77cb5 base: Change the type of the address in the ArchState statement 
ArchMemAddr is easier to use than ArchAddrWord in downstream clients, and is

372d7d7208 Add a new macaw statement to record updates to machine registers 
The new statement is called `ArchState`, and has two fields: an address and a
map.  The address is the address of the instruction it is standing in for.  The
map contains a mapping from the *machine registers* that the instruction updated
to the *macaw values* that were assigned to those locations.

This is useful metadata for debugging, but is also required to do some types of
architecture-independent analysis (where we can still reason about machine
register contents).

Use architecture-specific identifyReturn in Discovery process. 
Instead of inline analysis of whether the instruction pointer has been
updated to contain the ReturnAddr symbolic value, defer the
determination of the call return to the (previously defined but
unused) architecture-specific handling.  This allows architectures
like ARM that perform modifications on the values loaded to the
instruction pointer (e.g. clearing lower bits) to provide their own
recognition of a return operation.

Also modifies the signature of identifyReturn to return a Sequence of
statements to match the identifyCall type signature.

Replaces the previously unused identifyX86Return with the inline
detection of IP == ReturnAddr.
