This may break some stuff temporarily, but I want to
avoid the propagation of code that assumes this works.

null terminated name, and the system api's require null terminated 
strings anyway.

1) stop using MappedFile.
2) if profitable use the sys::path::MapInFilePages api to
   read the file.
3) otherwise fallback to read.

When sys::path::MapInFilePages is implemented, this provides
several benefits:

#1: this avoids fragmenting memory for small files.
#2: this avoids extraneous stat calls when the file size is known.
#3: this only keeps the file descriptor open while reading the 
    file, not for the duration of the lifetime of the memory 
    buffer.  This fixes a serious clang FD 'leak' problem.

I believe that this will work on a win32 machine, but I don't have
one to test on.  I'd appreciate it if someone could check.

not an mmapped file.  This more closely matches its requirements and
provides an implicitly null terminated buffer, something this
routine had to emulate itself before.

doesn't even work.

Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary
objects to a profile via dispatch to FoldingSetTrait<T>::Profile().

Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their
functionality is now replaced using the above mentioned member template.

Why?  Clients can now easily forward declare 'FoldingSetNodeID' without having
to include FoldingSet.h.
