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 b981326ae9 microkernel: remove last remnants of 'process' from text
There is no concept of a "process" in the system, so remove last
mentions of that concept from free-form text (doc, comments, macro
parameter names).

Allan Stephens 61fa627f74 doc: Terminology change - signalling -> synchronization
The kernel's services previously referred to as "signalling services",
which include object types such as semaphores, events, and mutexes,
are now referred to as "synchronization services". This term more
clearly conveys their use as a means to synchronize the operation
of two or more entities within the kernel.

Allan Stephens 46c5f12a1f doc: Overhaul of Zephyr Kernel Primer overview section
A complete rewrite of the Overview section. The revised text
provides a more logical and comprehensive introduction to the
main concepts and capabilities of Zephyr, without providing
an excessive level of detail. (Those details should be provided
by the remaining sections of the Kernel Primer.)

This rewrite has also resulted in some small changes to the
About Zephyr and other Kernel Primer sections.

Benjamin Walsh 87564a4602 pipes/mailboxes: rename functions using mem blocks
task_pipe_put_async -> task_pipe_block_put

  task_mbox_put_async -> task_mbox_block_put

  task_mbox_data_get_async_block -> task_mbox_data_block_get
  task_mbox_data_get_async_block_wait -> task_mbox_data_block_get_wait
  task_mbox_data_get_async_block_wait_timeout ->
       task_mbox_data_block_get_wait_timeout

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.

Removes an unnecessary level of headings in the microkernel and
nanokernel sections of the Zephyr kernel documentation, providing
users with direct access to the major service areas of the
microkernel and nanokernel from the main kernel web page. Also
greatly reduces the introductory text for these 2 sections,
since users can now easily find out what the various subsections
provide by simply clicking on them.
