Add gradient filter and JPEG compression with an heuristic to detect how
lossy the comppression will be. This code has been adapted from
libvncserver/tight.c.
JPEG support can be enabled/disabled at compile time with --enable-vnc-jpeg
and --disable-vnc-jpeg.

This commit adds subsections for each device section.
Subsections is the way to handle information that don't need to be sent
to de destination of a migration because its values are not needed. It is
the way to handle optional information. Notice that only the source can
decide if the information is optional or not. The destination needs to
understand all subsections that it receives to have a sucessful load.

This reverts commit ed487bb1d69040b9dac64a4fc076d8dd82b131d6.
The conflicts are due to commit 4fc8d6711aff7a9c11e402c3d77b481609f9f486
that is a fix to the ide_drive_pre_save() function. It reverts both

When hw interrupt pending bits in CP0_Cause are set, the CPU should
see the hw interrupt line as active. The CPU may or may not take the
interrupt based on internal state (global irq mask etc) but the glue
logic shouldn't care.
This fixes MIPS external hw interrupts in combination with -icount.

The request completion callback of the LSI controller may start the next
request that can use the same tag as the completed one. As the latter is
still enqueued at that point, scsi_send_command will complain about the
tag reuse and cancel the completed request. That will cause a double
free later on when the completion path cleans up as well.
Fix this by dequeuing the request before invoking the callback.

This change fixes initialization of e1000's microwire EEPROM internal
state values so that qemu's e1000 emulation works on NetBSD,
which doesn't use Intel's em driver but has its own wm driver
for the Intel i8254x Gigabit Ethernet.
Previously set_eecd() function in e1000.c clears EEPROM internal state
values on SK rising edge during CS==L, but according to FM93C06 EEPROM
(which is MicroWire compatible) data sheet, EEPROM internal status
should be cleared on CS rise edge regardless of SK input:
"... a rising edge on this (CS) signal is required to reset the internal
state-machine to accept a new cycle .."
and nothing should be changed during CS (chip select) is inactive.
Intel's em driver seems to explicitly raise SK output after CS is negated
in em_standby_eeprom() so many other OSes that use Intel's driver
don't have this problem even on the previous e1000.c implementation,
but I can't find any articles that say the MICROWIRE or EEPROM spec
requires such sequence, and actually hardware works fine without it
(i.e. real i82540EM has been working on NetBSD).
This fix also changes initialization to clear each state value in
struct eecd_state individually rather than using memset() against
the whole structre. The old_eecd member stores the last SK and CS
signal levels and it should be preserved even after reset of internal
EEPROM state to detect next signal edges for proper EEPROM emulation.

Guest debugging is currently broken under CONFIG_IOTHREAD. The reason is
inconsistent or even lacking signaling the debug events from the source
VCPU to the main loop and the gdbstub.
This patch addresses the issue by pushing this signaling into a
CPUDebugExcpHandler: cpu_debug_handler is registered as first handler,
thus will be executed last after potential breakpoint emulation
handlers. It sets informs the gdbstub about the debug event source,
requests a debug exit of the main loop and stops the current VCPU. This
mechanism works both for TCG and KVM, with and without IO-thread.

When checking for I/O events in the tcg CPU loop, make sure that we
call qemu_wait_io_event_common for all CPUs, not only the current one.
Otherwise pause_all_vcpus may lock up or run_on_cpu requests may starve.
Rename qemu_wait_io_event to qemu_tcg_wait_io_event at this chance and
purge its argument list as it has no use for it.

If a cpu_exit request is pending, ensure that we leave the CPU loop
quickly. For this purpose, keep the global exit_request pending until
we are about to leave tcg_cpu_exec. Also, immediately break out of the
SMP loop if the request is set, do not run till the end of the chain.
This preserves the VCPU scheduling order in SMP mode.

If a signal hit after the env->exit_request check but before cpu_exec
updated env->current_tb, cpu_unlink_tb called from the signal hander
will not unlink the current TB. This may leave us stuck in a guest loop
if no further unlink is invoked.
Fix this by reordering current_tb update and exit_request check,
additionally enforcing the correct order via a compiler barrier.
