47f8fd1d4d kernel: add K_INHERIT_PERMS flag
By default, threads are created only having access to their own thread
object and nothing else. This new flag to k_thread_create() gives the
thread access to all objects that the parent had at the time it was
created, with the exception of the parent thread itself.

d1f232c99a drivers: flash: Add API for retrieving a supported write-block-size
This path introduce API for retrieving a minimum write-block-size
supported by the flash driver.
This value can differ from the hardware alignment requirement
(as it does for nRF5x).

As the driver has a certain requirement for alignment
when writing, it is necessary to export this value for upper modules
which need to know the write-block-size (for instance, NFFS needs this).

0bfd810d13 i2c: deprecate use of union dev_config
There are several issues with the dev_config union used as a
convenience when calling the i2c_configure api.  One, the union is well
name spaced protected and doesn't convey use with just i2c.  Second
there are assumptions of how the bits might get packed by the union
which can't be guaranteed.  Since the API takes a u32_t lets change in
tree uses to using the macros to setup a u32_t and make the union as
deprecated.

c74983e8b4 kernel: remove some kernel objects from tracking
These are removed as the APIs that use them are not suitable for
exporting to userspace.

- Kernel workqueues run in supervisor mode, so it would not be
appropriate to allow user threads to submit work to them. A future
enhancement may extend or introduce parallel API where the workqueue
threads may run in user mode (or leave as an exercise to the user).

- Kernel slabs store private bookkeeping data inside the
user-accessible slab buffers themselves. Alternate APIs are planned
here for managing slabs of kernel objects, implemented within the
runtime library and not the kernel.

990bf16206 kernel: abolish __syscall_inline
This used to exist because in earlier versions of the system call
interfaces, an "extern" declaration of the system call implementation
function would precede the real inline version of the implementation.
The compiler would not like this and would throw "static declaration
of ‘foo’ follows non-static declaration". So alternate macros were
needed which declare the implementation function as 'static inline'
instead of extern.

However, currently the inline version of these system call
implementations appear first, the K_SYSCALL_DECLARE() macros appear in
the header generated by gen_syscalls.py, which is always included at the
end of the header file. The compiler does not complain if a
static inline function is succeeded by an extern prototype of the
same function. This lets us simplify the generated system call
macros and just use __syscall everywhere.

The disassembly of this was checked on x86 to ensure that for
kernel-only or CONFIG_USERSPACE=n scenarios, everything is still being
inlined as expected.
