1bab46dca1 ffs: rename find_[first|last]_set to find_[lsb|msb]_set
The new names reflect better what the functions do: they find the first
bit set starting from the least or most significant bit, i.e. they find
the least or most significant bit set, in a 32-bit word.

c4ad73d3b6 ffs: do not use _inline versions of find_[first|last]_set
Standardize on using the find_[first|last]_set (non-inline) symbols
everywhere.

The non-inline versions provide absolutely no benefits, so they will be
removed in a subsequent commit, and the inline versions will have their
_inline suffix removed.

a73af53186 timers: prevent duration of 0 in timer_start/restart
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.

b8693ad72b timers: consolidate task_timer_start/restart()

implementation of the user-facing API.

Instead of using ENDLIST, create a new internal _USE_CURRENT_SEM symbol

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_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.

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.

To support private memory map objects (aka, defining them within

This is done by creating a new section in binary, and all memory
map pointers go into this section. By doing this, the list
can still be manipulated as an array.

815d64522f microkernel: put pipe pointer list into its own binary section
The _k_pipe_list was a static array generated by sysgen,
where it containing all pre-defined pipes from MDEF file.
To support private pipe objects (aka, defining pipes within
source files), the pipe list has to accommodate pipes that
are not only processed through sysgen, but also those defined
within source files.

This is done by creating a new section in binary, and all pipe
pointers go into this section. By doing this, the pipe list
can still be manipulated as an array. The reason behind
putting the pointers to pipe, instead of the pipe objects
themselves, is that some compiler/linker may pad the large pipe
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.

2285976f03 microkernel: redefine pipe object identifier type

This change is a pre-requisite to support for private

This also moves the required struct into more visible
headers such that private pipes can be declared.
Renaming the struct is also being done to conform to
naming convention for private kernel objects.
Since a couple structs have to be moved anyway, so
do the moving and renaming here too (contrary to what
have been done in the past, with separated patches).

74c8852d05 microkernel: remove kernel service dispatch table
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.
