bsd-user upstreaming: read, write and exit
This series of patches continues the effort to get system calls working
upstream. This series was cleaved off a prior series to give me time to rework
based on the feedback from the first time I posted these. read, write and exit
are implemented, along with a few helper functions and tracing.

hw/block/fdc-sysbus: Always mark sysbus floppy controllers as not having DMA
The sysbus floppy controllers (devices sysbus-fdc and sun-fdtwo)
don't support DMA. The core floppy controller code expects this to
be indicated by setting FDCtrl::dma_chann to -1. This used to be
done in the device instance_init functions sysbus_fdc_initfn() and
sun4m_fdc_initfn(), but in commit 1430759ec3e we refactored this code
and accidentally lost the setting of dma_chann.
For sysbus-fdc this has no ill effects because we were redundantly
also setting dma_chann in fdctrl_init_sysbus(), but for sun-fdtwo
this means that guests which try to enable DMA on the floppy
controller will cause QEMU to crash because FDCtrl::dma is NULL.
Set dma_chann to -1 in the common instance init, and remove the
redundant code in fdctrl_init_sysbus() that is also setting it.
There is a six-year-old FIXME comment in the jazz board code to the
effect that in theory it should support doing DMA via a custom DMA
controller. If anybody ever chooses to fix that they can do it by
adding support for setting both FDCtrl::dma_chann and FDCtrl::dma.
(A QOM link property 'dma-controller' on the sysbus device which can
be set to an instance of IsaDmaClass is probably the way to go.)

target/mips: Fix emulation of nanoMIPS BPOSGE32C instruction
There are currently two problems related to the emulation of the
instruction BPOSGE32C.
The nanoMIPS instruction BPOSGE32C belongs to DSP R3 instructions
(actually, as of now, it is the only instruction of DSP R3). The
presence of DSP R3 instructions in QEMU is indicated by the flag
MIPS_HFLAG_DSP_R3 (0x20000000). This flag is currently being properly
set in CPUMIPSState's hflags (for example, for I7200 nanoMIPS CPU).
However, it is not propagated to DisasContext's hflags, since the flag
MIPS_HFLAG_DSP_R3 is not set in MIPS_HFLAG_TMASK (while similar flags
MIPS_HFLAG_DSP_R2 and MIPS_HFLAG_DSP are set in this mask, and there
is no problem in functioning check_dsp_r2(), check_dsp()). This means
the function check_dsp_r3() currently does not work properly, and the
emulation of BPOSGE32C can not work properly as well.
Change MIPS_HFLAG_TMASK from 0x1F5807FF to 0x3F5807FF (logical OR
with 0x20000000) to fix this.
Additionally, check_cp1_enabled() is currently incorrectly called
while emulating BPOSGE32C. BPOSGE32C is in the same pool (P.BR1) as
FPU branch instruction BC1EQZC and BC1NEZC, but it not a part of FPU
(CP1) instructions, and check_cp1_enabled() should not be involved
while emulating BPOSGE32C.
Rearrange invocations of check_cp1_enabled() within P.BR1 pool
handling to affect only BC1EQZC and BC1NEZC emulation, and not
BPOSGE32C emulation.

semihosting/config: Merge --semihosting-config option groups
Currently we mishandle the --semihosting-config option if the
user specifies it on the command line more than once. For
example with:
--semihosting-config target=gdb --semihosting-config arg=foo,arg=bar
the function qemu_semihosting_config_options() is called twice, once
for each argument. But that function expects to be called only once,
and it always unconditionally sets the semihosting.enabled,
semihost_chardev and semihosting.target variables. This means that
if any of those options were set anywhere except the last
--semihosting-config option on the command line, those settings are
ignored. In the example above, 'target=gdb' in the first option is
overridden by an implied default 'target=auto' in the second.
The QemuOptsList machinery has a flag for handling this kind of
"option group is setting global state": by setting
.merge_lists = true;
we make the machinery merge all the --semihosting-config arguments
the user passes into a single set of options and call our
qemu_semihosting_config_options() just once.

protocol:
* when setting up, if the user didn't explicitly select either
native semihosting or gdb semihosting, we autoselect, with the
intended behaviour "use gdb if gdb is connected"
* when the semihosting layer attempts to do a syscall via gdb, we
silently ignore it if the gdbstub wasn't actually set up
However, if the user's commandline sets up the gdbstub but tells QEMU
to start rather than waiting for a GDB to connect (eg using '-s' but
not '-S'), then we will have gdbserver_state.init true but no actual
connection; an attempt to use gdb syscalls will then crash because we
try to use gdbserver_state.c_cpu when it hasn't been set up:

You can probably also get into this state via some odd
corner cases involving connecting a GDB and then telling it
to detach from all the vCPUs.
Abstract out the test into a new gdb_attached() function
which returns true only if there's actually a GDB connected
to the debug stub and attached to at least one vCPU.

Move the computation from gen_swstep_exception into a helper.
This fixes a bug when:
- MDSCR_EL1.KDE == 1 to enable debug exceptions within EL_D itself
- we singlestep an ERET from EL_D to some lower EL
Previously we were computing 'same el' based on the EL which
executed the ERET instruction, whereas it ought to be computed
based on the EL to which ERET returned. This happens naturally
with the new helper, which runs after EL has been changed.
