Yonattan Louise 86ea4e6827 OS Awareness: Add microkernel object tracing.
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.

Dirk Brandewie 7a1e221733 init: add SYS_GET_DEVICE() macro to bury &__initconfig_* names usage.
Add a macro to retrieve the device structure for a config structure by
name.  This avoids the very error prone activity of the developer
having to *know* the way the internal object is named.

Dirk Brandewie ad5af93f25 x86: Add context value to loapic_mkstub and ioapic_mkstub macros
Add a context value to the ioapic and loapic mkstub macros to allow
the developer to specify a context value that will be passed on the
stack to the interrupt service routines.

All the invocations for the loapic_mkstub and ioapic_mkstub macros
have been changed to pass in 0 so there is no functional difference
ATM.  This change removes the need for drivers to have trampoline ISR
routines to pass a context vaule to their generic ISR routine.

This is the first step in getting rid of the hack where the driver
needs to look into the __initconfig_* linker objects.

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.

Peter Mitsis 5705d06874 x86: Properly initialize _interrupt_vectors_allocated[] bitmap
Updates the 'gen_idt' tool to generate a bitmap of (statically) allocated
interrupt vectors that is linked into the final image in a manner similar to
the static IDT. The kernel then uses this bitmap when dynamically connecting
an interrupt vector, thereby preventing the dynamic irq connections
from clobbering the static irq connections.

As a result of the addition of these two new fields, the gen_idt tool is

Fixes a bug in the x86 IRQ_CONNECT_STATIC() macro that resulted in setting
the DPL for the interrupt to the IRQ priority level.

Note 1: Using a proper value for the DPL (instead of the priority) prevents
the corruption of the other IDT fields.

Note 2: The priority of the IRQ is completely ignored.

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.

Daniel Leung 1c96cdeb52 i2c: simplify API and driver_api with generic transfer function
With the introduction of generic transfer function, it is no longer
needed to specify read or write functions explicitly in drivers.
All read/write functions can now thus call the generic transfer
function to achieve the same result.

With this change, the transfer function becomes mandatory, and
should always be available.

Daniel Leung ac0beb7034 i2c: add API for generic transfer
Add an API to I2C for generic transfer. This is for those data
transactions which are more complex than simple read or write.

One example use of this is to read register data from a slave
device. The master has to write the address of the register
to slave, then start reading from slave for register data.
In this situation, simple read or write is no longer
sufficient, as for some slave devices, they require RESTART
when data transfer direction changes. Doing a simple write via
i2c_write() results in STOP at end of transfer, which results
in the slave not responding to read request as it is not
expected to send anything back.
