hayodea 94982d50b9 IoUringAssmEngn: map StagingBuff w/mmap; reg w/io_uring; add eventFd 
StagingBuffer:
We now allocate memory with mmap(MAP_ANONYMOUS) so that we can be
sure it can be pinned with io_uring_register_buffers(). This
ensures that if DMA is possible, it should be usable.

	IoUringAssemblyEngine:
We now register an eventfd with io_uring so that we can listen
for CQEs with boost::asio.

hayodea 9a4f80a9d6 libAttachmentSupport: convert into shared lib 
This ensures that the support routines in this library will be
exposed at the same vaddr to each object in the vaddrspace.

hayodea 5845f1a41d Bug:Boost: Use shlibs instead of header-only for call_stack::top_ 
This symbol is defined as a static member object inside of a
boost detail header. When boost headers are used in a project
that uses Boost in both the main binary as well as dlopen()'d
shlibs, the top_ symbol gets duplicated and the metadata gets
partitioned.

We use the Boost shlib to unify both the main binary and the
shlibs to use the same memory address for top_.

This involves marking the templated object call_stack::top_ as
"extern" and then declaring to Boost that we intend to use the
shlibs.

hayodea b3bf0e2cb9 StimBuff,commonLibs: Add libattachmentSupport, move fnptrs into .cpp files 
We move the methods in StimulusBuffer whose addresses are taken during
program execution into a separate static lib. This guarantees that
they'll have their own, single vaddr at runtime, at least within
each independent code module.

but not be issuing pcloud data.
