Switch the SPARC target from the old unassigned_access hook to the
new do_transaction_failed hook.
This will cause the "if transaction failed" code paths added in
the previous commits to become active if the access is to an
unassigned address. In particular we'll now handle bus errors
during page table walks correctly (generating a translation
error with the right kind of fault status).

CPUClass method dump_statistics() takes an fprintf()-like callback and
a FILE * to pass to it. Most callers pass fprintf() and stderr.
log_cpu_state() passes fprintf() and qemu_log_file.
hmp_info_registers() passes monitor_fprintf() and the current monitor
cast to FILE *. monitor_fprintf() casts it right back, and is
otherwise identical to monitor_printf().
The callback gets passed around a lot, which is tiresome. The
type-punning around monitor_fprintf() is ugly.
Drop the callback, and call qemu_fprintf() instead. Also gets rid of
the type-punning, since qemu_fprintf() takes NULL instead of the
current monitor cast to FILE *.

The various TARGET_cpu_list() take an fprintf()-like callback and a
FILE * to pass to it. Their callers (vl.c's main() via list_cpus(),
bsd-user/main.c's main(), linux-user/main.c's main()) all pass
fprintf() and stdout. Thus, the flexibility provided by the (rather
tiresome) indirection isn't actually used.
Drop the callback, and call qemu_printf() instead.
Calling printf() would also work, but would make the code unsuitable
for monitor context without making it simpler.

with features converted to properties we can use the same
approach as x86 for features parsing and drop legacy
approach that manipulated CPU instance directly.
New sparc_cpu_parse_features() will allow only +-feat
and explicitly disable feat=on|off syntax for now.
With that in place and sparc_cpu_parse_features() providing
generic CPUClass::parse_features callback, the cpu_sparc_init()
will do the same job as cpu_generic_init() so replace content
of cpu_sparc_init() with it.

SPARCCPU::env was initialized from previously set properties
(with help of sparc_cpu_parse_features) in cpu_sparc_register().
However there is not reason to keep it there as this task is
typically done at realize time. So move post properties
initialization into sparc_cpu_realizefn, which brings
cpu_sparc_init() closer to cpu_generic_init().

It is a common thing amongst the various cpu reset functions want to
flush the SoftMMU's TLB entries. This is done either by calling
tlb_flush directly or by way of a general memset of the CPU
structure (sometimes both).
This moves the tlb_flush call to the common reset function and
additionally ensures it is only done for the CONFIG_SOFTMMU case and
when tcg is enabled.
In some target cases we add an empty end_of_reset_fields structure to the
target vCPU structure so have a clear end point for any memset which
is resetting value in the structure before CPU_COMMON (where the TLB
structures are).
While this is a nice clean-up in general it is also a precursor for
changes coming to cputlb for MTTCG where the clearing of entries
can't be done arbitrarily across vCPUs. Currently the cpu_reset
function is usually called from the context of another vCPU as the
architectural power up sequence is run. By using the cputlb API
functions we can ensure the right behaviour in the future.

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
