NMD class has been deleted. The following methods are now declared as
static functions:
- public NMD::Disassemble method
- private NMD::Disassemble method
- private NMD::extract_op_code_value helper method
Also, the implementation of the print_insn_nanomips function and
nanomips_dis function is moved to the end of the nanomips.cpp file,
right after the implementation of the Disassemble function.

Pool tables are no longer declared as static fields of the NMD
class but as global static const variables. Pool struct is defined
outside of the class.
The NMD::Disassemble method is using the MAJOR Pool table variable, so
its implementation is moved to the end of the nanomips.cpp file,
right after the initialization of the MAJOR Pool table.

NMD class methods with the disassembly_function type like
NMD::ABS_D, NMD::ABS_S, etc. are removed from the class. They're now
declared global static functions. Therefore, typedef of the function
pointer, disassembly_function is defined outside of the class.
Now that disassembly_function type functions are not part of the NMD
class we can't access them using the this pointer. Thus, the use of
the this pointer has been deleted.

Helper methods from NMD class like NMD::renumber_registers,
NMD::decode_gpr_gpr4... etc. are removed from the class. They're now
declared global static functions.
Following helper methods have been deleted because they're not used by
the nanomips disassembler:
- NMD::encode_msbd_from_pos_and_size,
- NMD::encode_s_from_s_hi,
- NMD::neg_copy
Global functions used by those methods:
- nanomips_dis
- sign_extend
- extract_bits
have also been defined as static global functions.

We're deleting the m_pc field of the NMD class. It's now part of the
Dis_info struct that this patch introduces. Currently, the Dis_info
struct has just one field, m_pc, which we need for address calculation
in the ADDRESS function.
We're filling Dis_info at the entrance of the nanoMIPS disassembler.
I.e. print_insn_nanomips. Next, we're adding that information as an
argument wherever we need to.
Since NMD class now has no more fields, the NMD constructor is
also deleted.

The m_requested_instruction_categories field always has the same value,
ALL_ATTRIBUTES. The only use of that field is within the if statement.
When replaced with a specific value, the if statement is always false,
so it has been removed.
Now, when the only use of the m_requested_instruction_categories field
is removed, we can delete the field declaration and initialization in
the NMD class. Also, we're changing the way of the construction of the
NMD object in the nanomips_dis function.

Since there's no namespace feature in C, namespace img has been replaced
with adding the prefix "img" to the namespace members.
Prefix "img" has been added to the function names of functions that used
to be wrapped in namespace img. Those are img::format() functions.
I.e. replaced img::format with the img_format.
Typedef address that used to belong to namespace img now is called
img_address.

At present packaging the required DLLs of QEMU executables is a
manual process, and error prone.
Actually build/config-host.mak contains a GLIB_BINDIR variable
which is the directory where glib and other DLLs reside. This
works for both Windows native build and cross-build on Linux.
We can use it as the search directory for DLLs and automate
the whole DLL packaging process.

When `-D ${logfile} -d tid` is passed, qemu_log_trylock() creates
a dedicated log file for the current thread and opens it. The
corresponding file descriptor is cached in a __thread variable.
Nothing is done to close the corresponding file descriptor when the
thread terminates though and the file descriptor is leaked.
The issue was found during code inspection and reproduced manually.
Fix that with an atexit notifier.

Specify maximum possible APIC ID assigned for current VM session to KVM
prior to the creation of vCPUs. By this setting, KVM can set up VM-scoped
data structure indexed by the APIC ID, e.g. Posted-Interrupt Descriptor
pointer table to support Intel IPI virtualization, with the most optimal
memory footprint.
It can be achieved by calling KVM_ENABLE_CAP for KVM_CAP_MAX_VCPU_ID
capability once KVM has enabled it. Ignoring the return error if KVM
doesn't support this capability yet.

This patch adds support for asynchronously tearing down a VM on Linux.
When qemu terminates, either naturally or because of a fatal signal,
the VM is torn down. If the VM is huge, it can take a considerable
amount of time for it to be cleaned up. In case of a protected VM, it
might take even longer than a non-protected VM (this is the case on
s390x, for example).
Some users might want to shut down a VM and restart it immediately,
without having to wait. This is especially true if management
infrastructure like libvirt is used.
This patch implements a simple trick on Linux to allow qemu to return
immediately, with the teardown of the VM being performed
asynchronously.
If the new commandline option -async-teardown is used, a new process is
spawned from qemu at startup, using the clone syscall, in such way that
it will share its address space with qemu.The new process will have the
name "cleanup/<QEMU_PID>". It will wait until qemu terminates
completely, and then it will exit itself.
This allows qemu to terminate quickly, without having to wait for the
whole address space to be torn down. The cleanup process will exit
after qemu, so it will be the last user of the address space, and
therefore it will take care of the actual teardown. The cleanup
process will share the same cgroups as qemu, so both memory usage and
cpu time will be accounted properly.
If possible, close_range will be used in the cleanup process to close
all open file descriptors. If it is not available or if it fails, /proc
will be used to determine which file descriptors to close.
If the cleanup process is forcefully killed with SIGKILL before the
main qemu process has terminated completely, the mechanism is defeated
and the teardown will not be asynchronous.
This feature can already be used with libvirt by adding the following
to the XML domain definition to pass the parameter to qemu directly:
<commandline xmlns="http://libvirt.org/schemas/domain/qemu/1.0">
<arg value='-async-teardown'/>
</commandline>

Commit 47e83d9107 ended up unintentionally changing the control flow
of ppc_radix64_process_scoped_xlate(). When guest_visible is false,
it must not raise an exception, even if the radix configuration is
not valid.
This regression prevented Linux boot in a nested environment with
L1 using TCG and emulating KVM (cap-nested-hv=on) and L2 using
KVM. L2 would hang on Linux's futex_init(), when it tested how a
futex_atomic_cmpxchg_inatomic() handled a fault, because L1 would
start a loop of trying to perform partition scoped translations
and raising exceptions.

Profiling QEMU during Fedora 35 for PPC64 boot revealed that
6.39% of total time was being spent in helper_insns_inc(), on a
POWER9 machine. To avoid calling this helper every time PMCs had
to be incremented, an inline implementation of PMC5 increment and
check for overflow was developed. This led to a reduction of
about 12% in Fedora's boot time.
