target-xtensa: avoid double-stopping at breakpoints

env->exception_taken is set every time an exception is taken. It is used
to allow single-stepping to stop at the first exception handler
instruction. This however must exclude debug exceptions, as otherwise
first step from the instruction where breakpoint was hit stops at that
same instruction.
Also don't check env->exception_taken directly from the
gen_intermediate_code_internal, instead allocate and use TB flag
XTENSA_TBFLAG_EXCEPTION.

xhci: fix segfault

Guest trying to reset a endpoint of a disconnected device resulted in
xhci trying to dereference uport while being NULL, thereby crashing
qemu.  Fix that by adding a check.  Drop unused dev variable while
touching that code bit.

qemu-ga: build it even if !system

Move qemu-ga build check out of if softmmu.. into its own section.
We want to build qemu-ga for _guest_ even if system build isn't
done.  It is controlled separately using --enable-guest-agent.
Additionally, give error message if guest agent is requested but
not supported.

block/iscsi.c: Fix printf format error.

The error on armv7hl was:

block/iscsi.c: In function ‘is_request_lun_aligned’:
block/iscsi.c:251:26: error: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘int64_t’ [-Werror=format=]

                          ^

This also splits the long line to comply with qemu coding guidelines.

block: Disable driver-specific options for 1.6

We don't want to commit to the API yet before everything is worked out.
Like already for 1.5, disable it again for the 1.6 release. This commit
is meant to be reverted after the 1.6 release.

The disabling of the driver-specific options is achieved by applying the
old checks while parsing the command line.

pcnet: Flush queued packets on end of STOP state

Analogously to other NICs, we have to inform the network layer when
the can_receive handler will no longer report 0. Without this, we may
get stuck waiting on queued incoming packets.
