Daniel Leung 1367a98e9e Redefine microkernel task object identifier type
The opaque task object id type is now a pointer to
the associated task structure, rather than an index
into the microkernel's array of task structures.

This change is a pre-requisite to support for private
task objects, which are defined in source code.

Daniel Leung 39887c4358 microkernel: introduce support for private mailboxes
This enable defining mailboxes in source code in addition to
defining in MDEF files. This introduces the macro
DEFINE_MAILBOX(mailbox_name). The mailboxes created this
way are the same, in functionality, as those defined in MDEF
files. They can be manipulated by the standard microkernel
mailbox APIs.

Define the mailbox using:

  DEFINE_MAILBOX(mailbox1);

and "mailbox1" can be used, for example:

  task_mbox_put(mailbox1, &msg);

or,

  task_mbox_get(mailbox1, &msg);

etc.

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

extern const kmox_t mailbox1;

to the desired C or header file.

Allan Stephens 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.

Daniel Leung 811c838ff1 microkernel: introduce support for private mutexes
This enable defining mutexes in source code in addition to
defining in MDEF files. This introduces the macro
DEFINE_MUTEX(mutex_name). The mutexes created this way are
the same, in functionality, as those defined in MDEF files.
They can be manipulated by the standard microkernel

Sample usage:

    DEFINE_MUTEX(mutex1);

    void one_function(void)
    {
        task_mutex_lock_wait(mutex1);
        ...
        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.

Daniel Leung 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.
