Juan Manuel Cruz 4613fc8c74 arc: adapt to standard IRQ_CONNECT_STATIC signature.
IRQ_CONNECT_STATIC takes 6 arguments on other
architectures, but the ARC one had only 5.

Andrew Boie 2ec374a8df irq_offload: ARC implementation
Uses the "trap_s" exception to simulate entry into IRQ context;
offloaded functions run on the FIRQ stack.

Dmitriy Korovkin f1420515a7 irq: Add flags to IRQ_CONNECT_STATIC() macro and irq_connect() function
Flags allow passing IRQ triggering option for x86 architecture.
Each platform defines flags for a particular device and then
device driver uses them when registers the interrupt handler.

The change in API means that device drivers and sample
applications need to use the new API.

IRQ triggering configuration is now handled by device drivers
by using flags passed to interrupt registering API:
IRQ_CONNECT_STATIC() or irq_connect()

drivers to ARC architecture hiding arch specific calls under generic
functions. On ARC, auxiliary registers is conceptually comparable to
x86 ports, thus the possibility to bring sys_in/sys_out to access those.

Tomasz Bursztyka b4e795b78c arc: Fix the sys_io.h operations to work on both registers and addresses
- Finally switched from ldw/stw to ldh/sth, as Benjamin noticed in an
  earlier comment (I was using ARC ISA, and not ARC V2 ISA). So indeed
  ldw/stw are obsolete and equivalent to ldh/std.

- clear, set and test were not working in case of using a memory address
  which would not point to a register: bclr, bset and btst requires
  registers as operands, and cannot deal with pure memory address (i.e.
  something like [rx] is not valid), thus the requirement to load first
  the value pointed by the address into a register, operate on that
  register and storing the result of it into the pointed address.

Benjamin Walsh 0dcad8331b clarify use of term 'context'
The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.

APIs that had their names changed:

  - nano_context_id_t is now nano_thread_id_t
  - context_self_get() is now sys_thread_self_get()
  - context_type_get() is now sys_execution_context_type_get()
  - context_custom_data_set/get() are now
    sys_thread_custom_data_set/get()

The 'context' prefix namespace does not have to be reserved by the
kernel anymore.

The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):

  - struct ccs is now struct tcs
  - tCCS is now tTCS

Benjamin Walsh c1f9fd888d irq: make utility functions private
irq_handler_set, irq_priority_set and irq_disconnect have been made
private by prepending an underscore to their names:

	irq_priority_set -> irq_priority_set
	irq_disconnect -> irq_disconnect

The prototypes have been removed from header files when possible, and
extern statements used in C code where they were called.

_irq_priority_set() for ARM is still in the header file because
IRQ_CONFIG() relies on it.
