Revert "Parallelize depend file generation"
This reverts commit d5b6ec450f.

parallel depend ddc does not significantly speed up compilation,
intermediately generated .ddc files can cause problems if compilation is interrupted unexpectedly

Ville Juven 0476e30a6d mm/kmm_map: Add support to dynamically map pages into kernel virtual memory
This adds functionality to map pages dynamically into kernel virtual
memory. This allows implementing I/O remap for example, which is a useful
(future) feature.

Now, the first target is to support mapping user pages for the kernel.

Why? There are some userspace structures that might be needed when the
userspace process is not running. Semaphores are one such example. Signals
and the WDT timeout both need access to the user semaphore to work
properly. Even though for this only obtaining the kernel addressable
page pool virtual address is needed, for completeness a procedure is
provided to map several pages.

Jukka Laitinen 7f8bec7070 Add mm/mm_map virtual memory mapping list
The task_group specific list can be used to store information about
mmappings.

For a driver or filesystem performing mmap can also enable munmap by
adding an item to this list using mm_map_add(). The item is then
returned in the corresponding munmap call.

SPRESENSE e249a2f82f Makefile: Fix Make.dep not updated by config changes
Make.dep file should be updated by .config changed after first make.
There are 2 cases affected for this problem:

 1) Add source files by config symbol
 2) Include header files in #ifdef directive

These 2 cases may not be included in Make.dep and this may prevent the
differential build from working correctly.

Gregory Nutt d1a8a803e4 Build system: Get rid of the MOVEOBJ definition
Eliminate the MOVEOBJ definition from tools/Config.mk, Makefiles, and other locations.  The MOVEOBJ definition was used to work around the case where the object output of a compile or assemble is in a different directory than the source file.  The ZDS-II tools have no command line option to perform this move; MOVEOBJ handled the move as a post-compiler operation.

MOVEOBJ is no longer needed because this the ez80 COMPILE and ASSEMBLE definitions now handle all of the object file movement cases.
