185b1cb1b7 libc/string: strcmp/strncmp cast unsigned char
Summary:
- Cast to unsigned char for strcmp and strncmp
- strcmp and strncmp are described following by opengroup.org

  The sign of a non-zero return value shall be determined by the sign
  of the difference between the values of the first pair of bytes
  (both interpreted as type unsigned char) that differ in the strings
  being compared.

  https://pubs.opengroup.org/onlinepubs/9699919799/functions/strcmp.html
  https://pubs.opengroup.org/onlinepubs/9699919799/functions/strncmp.html

Impact:
- strcmp and strncmp return value

Summary:
- I noticed that maix-bit:smp does not work with QEMU.
- Actually, QEMU supports sifive_u (not K210) but it works
  if FPU is disabled.
- This commit fixes this issue.

Impact:
- K210 with QEMU only

Testing:
- Tested with qemu-5.2

d6ef4849a9 syscall: Add call gate for get_environ_ptr
Now that the environment strings are stored as an array of strings,
they can be passed from the application via char **environ, which
is really defined as a function call to get_environ_ptr().

This works as is for flat build, but protected mode and kernel mode
require a call gate, which is added here.

4c1b66246d env_dup: Fix copying of env between address environments
If address environments are in use, it is not possible to simply
memcpy from from one process to another. The current implementation
of env_dup does precisely this and thus, it fails at once when it is
attempted between two user processes.

The solution is to use the kernel's heap as an intermediate buffer.
This is a simple, effective and common way to do a fork().

Obviously this is not needed for kernel processes.

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.
