09e7987121 sched/addrenv: Fix system crash when process group has been deleted
There is currently a big problem in the address environment handling which
is that the address environment is released too soon when the process is
exiting. The current MMU mappings will always be the exiting process's, which means
the system needs them AT LEAST until the next context switch happens. If
the next thread is a kernel thread, the address environment is needed for
longer.

Kernel threads "lend" the address environment of the previous user process.
This is beneficial in two ways:
- The kernel processes do not need an allocated address environment
- When a context switch happens from user -> kernel or kernel -> kernel,
  the TLB does not need to be flushed. This must be done only when
  changing to a different user address environment.

Another issue is when a new process is created; the address environment
of the new process must be temporarily instantiated by up_addrenv_select().
However, the system scheduler does not know that the process has a different
address environment to its own and when / if a context restore happens, the
wrong MMU page directory is restored and the process will either crash or
do something horribly wrong.

The following changes are needed to fix the issues:
- Add mm_curr which is the current address environment of the process
- Add a reference counter to safeguard the address environment
- Whenever an address environment is mapped to MMU, its reference counter
  is incremented
- Whenever and address environment is unmapped from MMU, its reference
  counter is decremented, and tested. If no more references -> drop the
  address environment and release the memory as well
- To limit the context switch delay, the address environment is freed in
  a separate low priority clean-up thread (LPWORK)
- When a process temporarily instantiates another process's address
  environment, the scheduler will now know of this and will restore the
  correct mappings to MMU

Why is this not causing more noticeable issues ? The problem only happens
under the aforementioned special conditions, and if a context switch or
IRQ occurs during this time.

de1c184e6c boards/sim: support rc.sysinit
Follow: http://glennastory.net/boot/sysinit.html

This is first script that init runs is rc.sysinit. This
script does serval initialization tasks about basic service.

The boot sequence currently provided to the board level is:
board_earlyinitialize->
    board_lateinitialize(Peripherals driver, core driver, ...)->
	run rcS script(mount fs, run service) ->
	    board_appinitialize->

After this patch:
The boot sequence currently provided to the board level is:
board_earlyinitialize->
    board_lateinitialize(core driver,...)->
	run rc.sysinit script(mount fs, run core service) ->
	    board_appinitialize(Peripherals driver)->
		run rcS script(run other service)->

So, Peripheral drivers can do more with the file system and
core services.

c15b6701ce RISC-V: Implement option to run NuttX in supervisor mode (S-mode)
- Add config "ARCH_USE_S_MODE" which controls whether the kernel
  runs in M-mode or S-mode
- Add more MSTATUS and most of the SSTATUS register definitions
- Add more MIP flags for interrupt delegation
- Add handling of interrupts from S-mode
- Add handling of FPU from S-mode
- Add new context handling functions that are not dependent on the trap
  handlers / ecall

NOTE: S-mode requires a companion SW (SBI) which is not yet implemented,
      thus S-mode is not usable as is, yet.

## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.

This PR cleans up the logic so they're only listed once.

 ## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!

 ## Testing
CI will test all build
