The microkernel server now relies on the fact that the command packets,
events, and semaphores passed to it via its command stack are 32 bit
aligned. This change explicitly ensures this alignment, rather than
leaving it to the compiler's discretion.

Revises microkernel semaphore sub-system to allow ISRs and fibers
to give a semaphore without having to define a command packet set.
The microkernel server now supports a 3rd command type on its
command stack, allowing a semaphore to be given in a similar manner
to the one used for the existing "give event" command type.

This patch enables defining microkernel events within source code.
This is similar to other private kernel object patches.
The test has been modified a little bit due to the fact that
the event ID is now a memory address, instead of numeric ID.

Add a list for each kind of microkernel object. Add the register of
the public objects to the tracing lists in the dynamic initialization
function of sysgen.

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.
