e510742d43 microkernel: introduce support for private FIFOs
This enable defining FIFOs in source code in addition to
defining in MDEF files. This introduces the macro
DEFINE_FIFO(fifo_name). The FIFOs created this
way are the same, in functionality, as those defined in MDEF
files. They can be manipulated by the standard microkernel
FIFO APIs.

Define the FIFO using:

  DEFINE_FIFO(fifo1, depth, width);

and "fifo1" can be used, for example:

  task_fifo_put(fifo1);

or,

  task_fifo_get(fifo1);

etc.

To use the FIFO defined in another source file, simply add:

extern const kfifo_t fifo1;

to the desired C or header file.

This is in preparation to enable private FIFO support.
The struct needs to be moved into more visible header
so private FIFOs can be declared. This also renames
according to naming convention to be private kernel
objects.

the associated FIFO structure, rather than an index
into the microkernel's array of FIFO structures.

8232067646 samples/microkernel: add test for private semaphores
This adds unit test for microkernel private semaphores.
The code piggybacks to the public semaphores tests (by
including the same source files), so any updates to
the test will be applied to both.

Note that the prj.mdef are different for both tests, since
the private semaphores test move some of the semaphores
inside source code.

eddae0e0f2 sysgen: Don't generate mutex object id variables
It is no longer necessary to generate variables containing the
object id each public mutex. This capability was once needed to
allow kernel code to reference mutexes generated by the build
system (i.e. pseudo-private mutexes); however, the existence of
private mutexes renders this obsolete.

        ...
        task_mutex_unlock(mutex1);
    }

To use the mutex defined in another source file, simply add:

    extern const kmutex_t mutex1;

to the desired C or header file.

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.

2. A shorter prompt works better with menuconfig.
3. Removes IOAPIC selection as HPET_TIMER selection makes it implicit.
4. Removes LINK_AUX_COMPILER_LIBS selection as it does not exist.
5. Removes CPU_MINUTEIA selection to permit CPU_ATOM as a valid choice.

8b0271dd2c Adapt HPET driver to work with QEMU
Qemu implements HPET so that it is connected to IRQ 2, which makes
necessary to use it in legacy emulation mode.

Add legacy emulation mode to HPET driver.

Change the way the HPET driver is initialized. QEMU requires that
the mode (one shot or periodic) gets set prior loading comparator
value.

Add debugging mode to HPET driver to ease the next port.

9aeb08213f toolchain: add support for iamcu toolchain
See
https://groups.google.com/forum/#!topic/ia32-abi/cn7TM6J_TIg

for more details.

• Support IA32 without FPU.
• Minimum ISA: Pentium ISA without x87 FPU instructions.
• Don't allow mixing i386 object files with Intel MCU object files.
• Support floating point with software emulation:
     a. Long double is the same as double.
     b. Use __float80 for 80-bit double.
• Minimize memory footprint:
     a. Code size
     b. Data size
     c. Stack size

Here is the draft of Intel MCU psABI.   The differences from IA32
 psABI are

1. The minimum instruction set is Intel Pentium ISA minus instructions
for x87 floating point unit.
2. There are no x87 floating point registers.
3. There are no vector registers.
4. Segment registers are optional.
5. Support for TLS relocations are optional.
6. Scalar types larger than 4 bytes are aligned to 4 bytes.
7. There are no vector types.
8. _Decimal32, _Decimal64, and _Decimal128 types are optional.
9. long double type is the same as double.
10. float, double and long double types are passed and returned in
 general purpose registers.
11. _Decimal32 and _Decimal64 types are passed in general purpose
registers.
12. Aggregate types no larger than 8 bytes are passed and returned
in general purpose registers.
13. Stack is 4-byte aligned.
14. The auxiliary vector support is optional.
15. Register %edx has undefined value at process entry.
16. New ELF machine code: EM_IAMCU.
17. New predefined C/C++ pre-processor symbols: __iamcu and __iamcu__
