To make the documentation readable from the source I want to get rid of the
substitutions for the project name an code name. This does not add any values
and makes it unreadable when looking at the text files directly. It also causes
some issues when people use those without actually knowing what they represent,
resulting in some weird and redundant language.

This patch is based on some code contributed by Dirk Brandewie.
This is a generic data structure for queuing data in a FIFO ring
buffer. Any given data enqueued is annotated with an app-specific
type identifier, and small integral value. Use of a data pointer
is optional if the necessary information can be conveyed in the
annotations. We want all the metadata to fit in a single DWORD.
The ring buffer always contains at least one free dword in the
buffer to correctly distinguish between full and empty queues.
Concurrency control is almost nonexistent; depending on usage,
apps may want to introduce the usage of semaphores and/or mutexes
to preserve the integrity of the ring buffer or provide notifications
when data is available.

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

Previous names, focusing on 'async', were misleading, because:
- some of those APIs can be used synchronously as well
- other APIs can also do asynchronous transfer, and don't have 'async'
in their names
- the key concept of these APIs is that they use memory pool blocks
rather than raw data buffers.
