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()

This functions - reusing _arc_v2_aux_reg_* ones - will ease porting
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.

- 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.

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

irq_handler_set, irq_priority_set and irq_disconnect have been made
private by prepending an underscore to their names:
irq_handler_set -> irq_handler_set
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.
