Daniel Leung 851c6f8f60 microkernel: introduce private event objects
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.

Allan Stephens f330d5adfe microkernel: Don't initialize packets in a command packet set
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.

Allan Stephens 6ac33f2b9f kernel: Introduce sys_thread_busy_wait() API
Provides a way for a fiber or task to busy wait for a specified
period of time. This is useful in situations where a delay needs
to be performed without switching execution to another context,
such as:

1) It would take longer to switch to another context and then switch
   back again than to simply busy wait.

2) A delay is required by the kernel's main task (i.e. the nanokernel's
   background task or the microkernel's idle task). This task is not
   allowed to voluntarily relinquish the CPU because this would leave
   the kernel with nothing to execute in its place.

Allan Stephens ddaebc15b3 kernel: Eliminate use of main() in microkernel
Revises microkernel initialization code by incorporating the existing
_k_kernel_init() and main() routines into _main(). This optimizes kernel
initialization a bit, and allows application code to use main()
if desired -- for example, as the entry point to an application task.
The change also eliminates the need for sysgen to generate a routine
whose content is always the same.

This change preserves the existing order of operations done during
kernel initialization, and leaves further improvements for later.

Daniel Leung 8253b90cfc microkernel: add task pointer list
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.

Andrew Boie f18f102feb nanokernel: add optional ring buffer data type
This patch is based on some code contributed by Dirk Brandewie.

This is a generic data structure for queuing data in a FIFO ring
buffer. Any given data enqueued is annotated with an app-specific
type identifier, and small integral value. Use of a data pointer
is optional if the necessary information can be conveyed in the
annotations. We want all the metadata to fit in a single DWORD.
The ring buffer always contains at least one free dword in the
buffer to correctly distinguish between full and empty queues.

Concurrency control is almost nonexistent; depending on usage,
apps may want to introduce the usage of semaphores and/or mutexes
to preserve the integrity of the ring buffer or provide notifications
when data is available.
