39b888bd88 Access BusState::allow_hotplug using wraper qbus_is_hotpluggable()
It would allow to transparently switch detection whether Bus
is hotpluggable from allow_hotplug field to hotplug_handler
link and to drop allow_hotplug field once all users are
converted to hotplug handler API.

49cec38591 tests: usb: usb-uas hotplug test
checks that it's possible to hotplug usb-uas HBA and
then if it's possible to hot(un)plug scsi-disk to it.
Thest basically covers hot(un)plug on dummy HBAs

b6ca82feed tests: usb: usb-storage hotplug test
usb-storage is different from usual usb devices
in that it uses a child SCSI bus for underlying storage.
This commit verifies that the SCSI bus is hotpluggable, as
hotplug operation wouldn't succeed without it.

b231c103af target-mips: fix broken MIPS16 and microMIPS
Commit 240ce26a broke MIPS16 and microMIPS support as it didn't
care those branches and jumps don't have delay slot in
MIPS16 and microMIPS.

This patch introduces a new argument delayslot_size to the
gen_compute_branch() indicating size of delay slot {0, 2, 4}.
And the information is used to call handle_delay_slot() forcingly
when no delay slot is required.

There are some microMIPS branch and jump instructions that requires
exact size of instruction in the delay slot. For indicating
these instructions, MIPS_HFLAG_BDS_STRICT flag is introduced.

Those fictional branch opcodes defined to support MIPS16 and
microMIPS are no longer needed.

To correct this, copy the copyright information and license from
savevm.c, that's where the original code came from.

Luckily, very few changes were made on qemu-file.c after it was created.
All the authors who touched the code are being CCed, so they can confirm
if they are OK with the copyright/license information being added.

The alternative is to munge names .e.g. with "-in" or "-out" suffixes

10dc65dbb8 target-mips: split decode_opc_special* into *_r6 and *_legacy
For better code readability and to avoid 'if' statements for all R6 and preR6
instructions whose opcodes are the same - decode_opc_special* functions are
split into functions with _r6 and _legacy suffixes.

*_r6 functions will contain instructions which were introduced in R6.
*_legacy functions will contain instructions which were removed in R6.
