Guile-JSON 3.x is incompatible with Guile-JSON 1.x, which we relied on
until now: it maps JSON dictionaries to alists (instead of hash tables),
and JSON arrays to vectors (instead of lists). This commit is about
adjusting all the existing code to this new mapping.

The default value of the argument REGISTER-CLOSURE? of the ISO9660-IMAGE,
QEMU-IMAGE and SYSTEM-DOCKER-IMAGE procedures can be computed automatically,
since the operating-system definition is available in its context. When the
operating-system definition does not contain the GUIX-SERVICE-TYPE, do not
register the closure in the database of Guix, as it takes time and doesn't
serve a purpose.
* gnu/system/vm.scm (has-guix-service-type): Add predicate.

value.

(system-docker-image)[register-closures?]: Likewise.
(system-disk-image): Do not explicit a value for the REGISTER-CLOSURES?
argument of the ISO9660-IMAGE and QEMU-IMAGE procedure calls, so that its
default value is used instead.
* guix/scripts/system.scm (system-derivation-for-action): Do not explicit a
value for the REGISTER-CLOSURES? argument of the SYSTEM-DOCKER-IMAGE
procedure call, so that its default value is used instead.
Fixes a bug whereby building an image containing non-ASCII file names

This is an incompatible change visible to users via the 'initrd' field

In practice virtio modules were always available since 'base-initrd' was
always called with #:virtio? #t. This commit simply moves them to
'%base-initrd-modules' so that 'guix system' knows they're available.

Fixes a regression introduced in
bc499b113a, whereby the default initrd
used by 'expression->derivation-in-linux-vm' would lack all the usual
modules: virtio, nls_iso8859-1, etc.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass
#:linux-modules to 'base-initrd'.
This avoids the hard-coded "/dev/sda1", which only made sense when the
image is run with "qemu-system-x86_64 -hda", not when it's passed to
Xen, etc.
Reported by Andreas Enge <andreas@enge.fr>.
* gnu/system/vm.scm (system-qemu-image): Define 'root-uuid', use it as
the 'device' field for "/", and pass it to 'qemu-image'.
This improves the performance of the shared store for operations involving
lots of files, e.g. searching through the store.
* gnu/system/vm.scm (mapping->file-system): Add cache=loose to options.

module during derivation building.
* gnu/scripts/system.scm (bootloader-installer-derivation): Ditto.
* gnu/build/vm.scm (load-in-linux-vm): New argument #:target-arm32.
Use it to adapt command for qemu-system-arm. This implies to choose a
machine ("virt"), use the correct console port "ttyAMA0", disable KVM use
that is buggy on some ARM boards (Odroid XU4 for example) and use user mode
network stack instead of NIC. Gather all those options in a new variable
"arch-specific-flags".
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass
to load-in-linux-vm "#:target-arm32?" argument.
* gnu/system/vm.scm (qemu-img): Do not add EFI partition if we are targetting
ARM.
UEFI support on u-boot is still experimental, so do not add EFI partition on
ARM for now.
* gnu/system/vm.scm (system-disk-image, system-qemu-image,
virtualized-operating-system): Replace base-initrd by
(operating-system-initrd os).
The system produced were always using base-initrd even if the user had
defined a custom initrd based on raw-initrd in the os declaration.
* gnu/system/vm.scm (operating-system-uuid): Use 2^32 - 1 instead of
2^32 as hash size.
On some 32 bit system (ARM for example), 2^32 exceeds hash max
size (ULONG_MAX = 2^32 - 1).
* gnu/system/vm.scm (qemu-image): When guessing the root-size, use a lower
bound of 20 MiB, otherwise the root file system size is sometimes 0 MiB in
size.
This makes collisions less likely than when using a label to look up the
partition. See <https://bugs.gnu.org/27735>.
* gnu/system/vm.scm (operating-system-uuid): New procedure.
(system-disk-image): Define 'root-uuid' and use it for the root file
system. Pass it to 'iso9660-image' and 'qemu-image'.
Conceptually a UUID is just a bytevector. However, there's software out
there such as GRUB that relies on the string representation of different
UUID types (e.g., the string representation of DCE UUIDs differs from
that of ISO-9660 UUIDs, even if they are actually bytevectors of the
same length). This new <uuid> record type allows us to preserve
information about the type of UUID so we can eventually convert it to a
string using the right representation.
* gnu/system/uuid.scm (<uuid>): New record type.
(bytevector->uuid): New procedure.
(uuid): Return calls to 'make-uuid'.
(uuid->string): Rewrite using 'match-lambda*' to accept a single 'uuid?'
