Previous names, focusing on 'async', were misleading, because:
- some of those APIs can be used synchronously as well
- other APIs can also do asynchronous transfer, and don't have 'async'
in their names
- the key concept of these APIs is that they use memory pool blocks
rather than raw data buffers.

The _k_pipe_list was a static array generated by sysgen,
where it containing all pre-defined pipes from MDEF file.
To support private pipe objects (aka, defining pipes within
source files), the pipe list has to accommodate pipes that
are not only processed through sysgen, but also those defined
within source files.
This is done by creating a new section in binary, and all pipe
pointers go into this section. By doing this, the pipe list
can still be manipulated as an array. The reason behind
putting the pointers to pipe, instead of the pipe objects
themselves, is that some compiler/linker may pad the large pipe
struct. For example, compiling under gcc and march=i686 pads
the struct to 32-byte alignment (march=atom to 64-byte alignment).
This causes issue with sizeof() and pointer arithmetic because
they have no idea about the padding. So use pointers here to
prevent padding.

The opaque pipe object id type is now a pointer to
the associated pipe structure, rather than an index
into the microkernel's array of pipe structures.
This change is a pre-requisite to support for private
pipes, which are defined in source code.
This also moves the required struct into more visible
headers such that private pipes can be declared.
Renaming the struct is also being done to conform to
naming convention for private kernel objects.
Since a couple structs have to be moved anyway, so
do the moving and renaming here too (contrary to what
have been done in the past, with separated patches).

This change removes the internal number-to-function mapping
of microkernel services. Instead, function pointers are used
to specify which service to use.
This is in preparation for private kernel objects. Before this,
only kernel objects that are defined in MDEF files would have
corresponding functions included in the final binary, via sysgen
by populating an array of number-to-function mapping. This
causes an issue when a certain type of objects are all defined
with source code, and never in MDEF file. The corresponding
mapping would be deleted, and the functions are never included
in the binary. For example, if no mutexes are defined in MDEF
file, the _k_mutex_*() functions would not be included.
With this change, any usage of private kernel objects will hint
to the linker that those functions are needed, and should not be
removed from final binary.
