Code implementing .receive_buf() callback can potentially call
serdev_device_write(), which will call serdev_device_poller(). We need
to make sure that such a call is a no-op in order to prevent
corrupting shared data buffer as well as breaking .receive_buf
callback that most likely does not expect that to happen.

It's hard to get more complicated things right in hush. This commit
converts the /env/bin/init script to C code. With this we get a better
error handling and better control what is being done.
If /env/bin/init exists in the environment then it is still executed
instead of the corresponding C code.

When global.autoboot_abort_key is set to ctrl-c then the user is
expected to press ctrl-c to get to the prompt. The user might press
ctrl-c before the init script runs the "timeout" command. In this
case the init script is aborted at arbitrary places which leads to
inconsistent results depending on the place it is aborted.
This patch introduces the global.console.ctrlc_allowed variable.
When this variable is set to false ctrl-c is ignored entirely.
The variable is set to false by default and changed to true in
the init script.

It's easy to get stuck in an infinite loop in the hush shell:
while true; do sleep 1; done
The 'sleep' command will check for ctrl-c with the ctrlc() function. This
will abort the sleep command. Hush then checks for ctrl-c again in the
loop. The ctrl-c in the buffer has already been eaten by the sleep
command, so the loop will continue.
With this patch we remember the presence of a ctrl-c character in a
variable instead of checking for a new character each time. The
variable must be resetted explicitly by calling ctrlc_handled() which
will be called by the shell in the outer loop.

In contrast to other architectures, R.Pi debug UART config was placed
under the "System Type" menu, not under the "Debugging -> low-level
debugging port". This made this setting easy to miss when enabling low
level debug mesages.
While at it use the existing base address defines rather than defining
them again in Kconfig.

For platforms such as the at91, the boot ROM imposes an upper limit
on barebox file size. Prior to 5a1a5ed253 ("ARM: images: use piggydata"),
BAREBOX_MAX_PBLX_SIZE seems to have been the way to go for limiting
the size of the final barebox binary when using the PBL.
With pblx removed, this variable is of no use, so have the existing
BAREBOX_MAX_IMAGE_SIZE replace its functionality.
Currently BAREBOX_MAX_IMAGE_SIZE is only checked against in the non-PBL
case, so add a check in the PBL case as well.

Since kernel 4.16 the memory nodes got a @<reg> suffix so the fixup
won't work correctly anymore, because instead of adapting the extisting
one the fixup creates a new node and keeps the old (maybe incorrect)
node.
To be compatible with the old and new layout delete the found memory
node and create a new one. The new node follows the new @<reg> style.
The patch also renames the node parameter to make it clearer.

Linux userspace with recent glibc versions lets barebox-state suffer from
linux/stat.h redefining 'struct statx' and because of that switched to the
inclusion of sys/stat.h instead, see dt-utils commit 1c80e31872ae ("src: fix
compilation for glibc version 2.27.9000-36.fc29 and newer").
We can follow this switch in barebox without any problems, too, as in barebox
sys/stat.h includes linux/stat.h (and adds some more definitions on top that
don't hurt us here).
