Reworks the internal design of a command packet set so that
the command packet array is split out into a separate variable
lying in uninitialized memory. This shrinks the command packet's
data section footprint to almost nothing.
Note: A side effect of this change is that it is no longer possible
to define a command packet set as a "static" variable since the
CMD_PKT_SET_INSTANCE() macro now generates two variables.

Due to similar padding issue as pipe, the list of task object
may not be used directly. As mentioned before, some compiler/linker
may pad the large 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.
When the stars align in a certain way, these task structs may be
corrupted. So add a task pointer list and use it for task
manipulation. The task list remains as it is beneficial to group
them together to take advantage of cache locality.

k_proc was a legacy leftover that does not make any sense, since there
is no concept of a "process" in the system. Rather, that data structure
refers to a 'task control block', i.e. the representation of a task
execution context from the microkernel's point-of-view (not to confuse
with the 'struct ccs', the representation of a thread execution context,
from the nanokernel's point-of-view).

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.

This enable defining memory maps in source code in addition to
defining in MDEF files. This introduces the macro
DEFINE_MEM_MAP(mem_map_name, ...). The memory maps created this
way are the same, in functionality, as those defined in MDEF
files. They can be manipulated by the standard microkernel
memory map APIs.
Define the memory map using:
DEFINE_MEM_MAP(mem_map1, blocks, block_size);
and "mem_map1" can be used, for example:
task_mem_map_alloc(mem_map1, ...);
or,
task_mem_map_free(mem_map1, ...);
etc.
To use the memory map defined in another source file, simply add:
extern const kmemory_map_t mem_map1;
to the desired C or header file.

The _k_mem_map_list was a static array generated by sysgen,
where it containing all pre-defined memory maps from MDEF file.
To support private memory map objects (aka, defining them within
source files), the list has to accommodate memory maps 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 memory
map pointers go into this section. By doing this, the list
can still be manipulated as an array.

The opaque memory map object id type is now a pointer to
the associated memory map structure, rather than an index
into the microkernel's array of memory map structures.
This change is a pre-requisite to support for private
memory map objects, which are defined in source code.

This enable defining pipes in source code in addition to
defining in MDEF files. This introduces the macro
DEFINE_PIPE(pipe_name, ...). The pipes created this
way are the same, in functionality, as those defined in MDEF
files. They can be manipulated by the standard microkernel
pipe APIs.
Define the pipe using:
DEFINE_PIPE(pipe1, size);
and "pipe1" can be used, for example:

or,
task_pipe_get(pipe1, ...);
etc.
To use the pipe defined in another source file, simply add:

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).
