Just a tiny cleanup inspired by the following comment:

I was just getting familiar with rts code base so I
thought might as well do this.

is used outside of the rts so we do this rather than just fish it out of
the repo in ad-hoc way, in order to make packages in this repo more
self-contained.

Pretty-printing CLabel relies on sdocWithDynFlags that we want to remove
(#10143, #17957). It uses it to query the backend and the platform.
This patch exposes Clabel ppr functions specialised for each backend so
that backend code can directly use them.

Separate word and string hash tables on the type level, and do not store
the hashing function. Thus when a different hash function is desire it
is provided upon accessing the table. This is worst case the same as
before the change, and in the majority of cases is better. Also mark the
functions for aggressive inlining to improve performance. {F1686506}

Previously there were numerous places in the RTS where we would fopen
with the "w" flag string. This is wrong as it will not truncate the
file. Consequently if we write less data than the previous length of the
file we will leave garbage at its end.
Fixes #16993.

Summary:
This shims out fopen and sopen so that they use modern APIs under the hood
along with namespaced paths.
This lifts the MAX_PATH restrictions from Haskell programs and makes the new
limit ~32k.
There are only some slight caveats that have been documented.
Some utilities have not been upgraded such as lndir, since all these things are
different cabal packages I have been forced to copy the source in different places
which is less than ideal. But it's the only way to keep sdist working.

In addition to more const-correctness fixes this patch fixes an
infelicity of the previous const-correctness patch (995cf0f356) which
left `UNTAG_CLOSURE` taking a `const StgClosure` pointer parameter
but returning a non-const pointer. Here we restore the original type
signature of `UNTAG_CLOSURE` and add a new function
`UNTAG_CONST_CLOSURE` which takes and returns a const `StgClosure`
pointer and uses that wherever possible.

The `nat` type was an alias for `unsigned int` with a comment saying
it was at least 32 bits. We keep the typedef in case client code is
using it but mark it as deprecated.

This will hopefully help ensure some basic consistency in the forward by
overriding buffer variables. In particular, it sets the wrap length, the
offset to 4, and turns off tabs.

Previously the code generator generated small code fragments labelled
with __stginit_M for each module M, and these performed whatever
initialisation was necessary for that module and recursively invoked
the initialisation functions for imported modules. This appraoch had
drawbacks:
- FFI users had to call hs_add_root() to ensure the correct
initialisation routines were called. This is a non-standard,
and ugly, API.
- unless we were using -split-objs, the __stginit dependencies would
entail linking the whole transitive closure of modules imported,
whether they were actually used or not. In an extreme case (#4387,
#4417), a module from GHC might be imported for use in Template
Haskell or an annotation, and that would force the whole of GHC to
be needlessly linked into the final executable.
So now instead we do our initialisation with C functions marked with
__attribute__((constructor)), which are automatically invoked at
program startup time (or DSO load-time). The C initialisers are
emitted into the stub.c file. This means that every time we compile
with -prof or -hpc, we now get a stub file, but thanks to #3687 that
is now invisible to the user.
There are some refactorings in the RTS (particularly for HPC) to
handle the fact that initialisers now get run earlier than they did
before.
The __stginit symbols are still generated, and the hs_add_root()
function still exists (but does nothing), for backwards compatibility.

Also changed exitcode of -1 to 1 in hpc.

The first phase of this tidyup is focussed on the header files, and in
particular making sure we are exposinng publicly exactly what we need
to, and no more.
- Rts.h now includes everything that the RTS exposes publicly,
rather than a random subset of it.
- Most of the public header files have moved into subdirectories, and
many of them have been renamed. But clients should not need to
include any of the other headers directly, just #include the main
public headers: Rts.h, HsFFI.h, RtsAPI.h.
- All the headers needed for via-C compilation have moved into the
stg subdirectory, which is self-contained. Most of the headers for
the rest of the RTS APIs have moved into the rts subdirectory.
- I left MachDeps.h where it is, because it is so widely used in
Haskell code.
- I left a deprecated stub for RtsFlags.h in place. The flag
structures are now exposed by Rts.h.
- Various internal APIs are no longer exposed by public header files.
- Various bits of dead code and declarations have been removed
- More gcc warnings are turned on, and the RTS code is more
warning-clean.
- More source files #include "PosixSource.h", and hence only use
standard POSIX (1003.1c-1995) interfaces.
There is a lot more tidying up still to do, this is just the first
pass. I also intend to standardise the names for external RTS APIs
(e.g use the rts_ prefix consistently), and declare the internal APIs
as hidden for shared libraries.

- .tix files are now a list of MixModule, which contain a hash of the contents of the .mix file.
- .mix files now have (the same) hash number.
This changes allow different binaries that use the same module compiled in the same way
to share coverage information.

- Now we use two pipes and a fork rather than use named pipes
- We use the HPCRIX env var to send the pipe numbers in %d:%d format
- We now always breakpoint for special events
- We check to see we are the original process before each breakpoint event
sub processes are not debugged; this lets us debug the debugger.

This large checkin is the new ghc version of Haskell
Program Coverage, an expression-level coverage tool for Haskell.
Parts:
- Hpc.[ch] - small runtime support for Hpc; reading/writing *.tix files.
- Coverage.lhs - Annotates the HsSyn with coverage tickboxes.
- New Note's in Core,
- TickBox -- ticked on entry to sub-expression
- BinaryTickBox -- ticked on exit to sub-expression, depending
-- on the boolean result.
- New Stg level TickBox (no BinaryTickBoxes, though)
You can run the coverage tool with -fhpc at compile time.
Main must be compiled with -fhpc.
