In order to provide the same irq_connect() on all platforms
on x86, irq_connect() now uses a static array of interrupt
stubs. Device driver does not need to provide interrupt stub
to irq_connect() function.
Add NUM_DYNAMIC_STUBS configuration parameter, the number
of interrupt stubs used for dynamic interrupt registration.
Modify tests for unified interrupt register API
Tests that deal with interrupts are modified to work
with the new interrupt registration API.
Add CONFIG_NUM_DYNAMIC_STUBS option to dynamic interrupt projects
Projects that use dynamic interrupt handler registration on x86
have to include CONFIG_NUM_DYNAMIC_STUBS parameter in the
configuration.

IRQ_CONNECT_STATIC() macro provides static interrupt registration.
It creates an entry for _sw_isr_table, table of interrupt handlers.
IRQ_CONFIG() macro provides interrupt controller configuration.
On ARM platform it configures the priority of each interrupt.
_sw_isr_table is implemented the way that each of it's elements
is located in individual section. Sections are marked a "linkonce",
thus when a device driver declares an interrupt handler, it overwrites
the default _sw_isr_table entry.

In order to simplify x86 interrupt stub creation, each interrupt
controller implements an interrupt stub definition macro.
Add IRQ_CONNECT_STATIC() for static interrupt registration, and
construct the interrupt stubs name from device and interrupt
handler names.
Add IRQ_CONFIG() macro for the interrupt controller configuration.
On x86 platform it programs APIC to associate an IRQ number with
the interupt vector.
Add HPET_TIMER0_INT_PRI parameter to Quark platform header to
make it build correctly.

CPU_CORTEX_M3_M4 replaces CPU_CORTEXM3 as the umbrella option for Cortex M3/M4
processors.
NOTE: Selecting CPU_CORTEXM4 still currently forces the selection of
CPU_CORTEXM3. Breaking that forced select will be done in a later commit.

header. Not only was the (deleted) list both incomplete and wrong, keeping
it around and properly updated requires error prone maintenance.
