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

k_proc was a legacy leftover that does not make any sense, since there
is no concept of a "process" in the system. Rather, that data structure
refers to a 'task control block', i.e. the representation of a task
execution context from the microkernel's point-of-view (not to confuse
with the 'struct ccs', the representation of a thread execution context,
from the nanokernel's point-of-view).

Basically, this does not work anymore:
task_timer_start(<timer>, 0, X, <sem>);
since it does not make much sense to have a timer with an expiry of 0
ticks. The code internally was setting the duration to be equal to the
period anyway. So, to achieve the same behaviour, do this:
task_timer_start(<timer>, X, X, <sem>);
This has the positive side-effect of removing a small block of logic
that was handling the cases where duration was 0.

putting the pointers to pipe, instead of the pipe objects

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. So use pointers here to
prevent padding.

This change removes the internal number-to-function mapping
of microkernel services. Instead, function pointers are used
to specify which service to use.
This is in preparation for private kernel objects. Before this,
only kernel objects that are defined in MDEF files would have
corresponding functions included in the final binary, via sysgen
by populating an array of number-to-function mapping. This
causes an issue when a certain type of objects are all defined
with source code, and never in MDEF file. The corresponding
mapping would be deleted, and the functions are never included
in the binary. For example, if no mutexes are defined in MDEF
file, the _k_mutex_*() functions would not be included.
With this change, any usage of private kernel objects will hint
to the linker that those functions are needed, and should not be
removed from final binary.
