Documentation states that init scripts are executed in order and this
had been the case before 90df2a955e. This patch replaced the shell loop
around /env/init/* with a plain readdir which is not sorted at all.
Iterate over the files with glob() which guarantees sorted results.

The PATH environment variable is set at the shell prompt, but it is not
exported, so currently scripts can't execute other scripts in PATH
anymore. PATH used to be exported in the init script, but this part was
lost when converting the init script to C. Add it back.

When the checksum tag is disabled the CRC is most likely invalid.
And if the checksum tag is disabled and the CRC is actually invalid the
user doesn't care for it anyway.
This information only confuses the user so make it a debug message.

As dropping exceptions is no relicense, it's ok to do here without

Like Linux, barebox supports co-existence of multiple watchdog
devices. On boot, barebox enables only the default watchdog, which
is defined as the watchdog with highest non-zero priority.
The kernel handles all watchdogs the same and defers to userspace,
which watchdogs to service. It can be useful to have barebox tell
the system, which watchdog it activated, so it can service the same.
Having this feature behind a global variable adds 354 bytes to a
LZO compressed THUMB2 barebox. Users can opt out by toggling the
Kconfig option, which defaults to off.

We have the split by '=' snippet at multiple locations that parse
key=value pairs. Consolidate them to a single location. This makes code
a bit easier to read at the cost of an extra 8 bytes (LZO-compressed
THUMB2 barebox, static inline version is bigger).
No functional change.

The Kconfig help text as well the function name
machine_id_set_bootarg() suggest that enabling the Kconfig option is
sufficient to have barebox pass the machine id to the kernel.

setenv(var, "") to delete var is a barebox idiosyncrasy. Previous commit
added unsetenv and changed all users of setenv(var, ""), so lets set the
behavior of setenv to what's expected: set var to the empty string.
Previously, "" was turned into NULL, which meant it wasn't possible to
set variables to the empty string from the shell. This is now possible.

nvvar_add results in two calls to dev_set_param:
- once when the existing global variable is found and set
- once more when setting the nv variable
This results in an annoying but ultimately harmless message on startup:
ERROR: USB multi gadget already registered
ERROR: failed to create nv variable usbgadget.autostart: Device or
resource busy
Avoid this by ignoring usbgadget.autostart=1 after it succeeded once.
This issue should only affect $global.usbgadget.autostart, because all
other global variables are "simple" meaning that they have no setters
triggered.

If the SDRAM is mapped to address 0x0 and an image should be loaded to
to the SDRAM without offset, Barebox would normally trap the access as a
null pointer.
However, since Linux kernel commit cfa7ede20f13 ("arm64: set TEXT_OFFSET
to 0x0 in preparation for removing it entirely") no offset is the
default for arm64. Therefore, copying the image to 0x0 of the SDRAM is
necessary.
Disable the zero page trap for copying an image to address 0x0.

While reboot mode magic identifiers can be very board specific, we can
settle on common names to allow some generic reboot mode handling:
- loader -> drop to bootloader shell on next boot
- bootloader -> enable fastboot on next boot
- recovery -> display barebox boot menu
Boot modes loader and bootloader are admittedly a bit ambiguous, but
this nomenclature was chosen, because it's already in use on Android and
Rockchip systems.

So far, global.usbgadget.autostart=1 from the shell was without effect,
because the variable is only evaluated once at postenvironment_initcall.
Use the new globalvar_add_bool() to allow acting on the variable being
true at any time. This is necessary for scripts that want to enable
the usbgadget autostart functionality selectively without themselves
hardcoding the particularities of what is exported.

We have a _LAST_ERRNO of 3 decimal digits. strerror(_LAST_ERRNO) is ok,
but it's still possible that some code passes a non-error code int,
which will overflow the static buffer. Play it safe and bump up the
buffer size to at least 11 characters. This is enough to represent
all integers, with only 7 characters more static storage.
This way strerror(some_int_passed_by_mistake) will not invoke UB.

The service will bind to the network interface that provides the IPv4
