The switch case of writing PCI 1 IO base address had an extra break
statement that made part of the code unreachable. This did not cause a
problem as guests ususally leave this register at its default value.

Setting SYSTEMTAP_TAPSET to some value other than
/usr/share/systemtap/tapsets results in systemtap not finding the
standard tapset library any more, which in turn breaks tracing because
pid() and other standard systemtap functions are not available any more.
So using SYSTEMTAP_TAPSET to point systemtap to the qemu probes will
only work for the prefix=/usr installs because both qemu and system
tapsets in the same directory then. All other prefixes are broken.
Fix that by using the "-I $tapsetdir" command line switch instead.

The recently-added NBD context qemu:allocation-depth is able to
distinguish between locally-present data (even when that data is
sparse) [shown as depth 1 over NBD], and data that could not be found
anywhere in the backing chain [shown as depth 0]; and the libnbd
project was recently patched to give the human-readable name "absent"
to an allocation-depth of 0. But qemu-img map --output=json predates
that addition, and has the unfortunate behavior that all portions of
the backing chain that resolve without finding a hit in any backing
layer report the same depth as the final backing layer. This makes it
harder to reconstruct a qcow2 backing chain using just 'qemu-img map'
output, especially when using "backing":null to artificially limit a
backing chain, because it is impossible to distinguish between a
QCOW2_CLUSTER_UNALLOCATED (which defers to a [missing] backing file)
and a QCOW2_CLUSTER_ZERO_PLAIN cluster (which would override any
backing file), since both types of clusters otherwise show as
"data":false,"zero":true" (but note that we can distinguish a
QCOW2_CLUSTER_ZERO_ALLOCATED, which would also have an "offset":
listing).
The task of reconstructing a qcow2 chain was made harder in commit
0da9856851 (nbd: server: Report holes for raw images), because prior
to that point, it was possible to abuse NBD's block status command to
see which portions of a qcow2 file resulted in BDRV_BLOCK_ALLOCATED
(showing up as NBD_STATE_ZERO in isolation) vs. missing from the chain
(showing up as NBD_STATE_ZERO|NBD_STATE_HOLE); but now qemu reports
more accurate sparseness information over NBD.
An obvious solution is to make 'qemu-img map --output=json' add an
additional "present":false designation to any cluster lacking an
allocation anywhere in the chain, without any change to the "depth"
parameter to avoid breaking existing clients. The iotests have
several examples where this distinction demonstrates the additional
accuracy.

Commit 3fe9a838ec "dp8393x: Always use 32-bit accesses" set .impl.min_access_size
and .impl.max_access_size to 4 to try and fix the Linux jazzsonic driver which uses
32-bit accesses.
The problem with forcing the register access to 32-bit in this way is that since the
dp8393x uses 16-bit registers, a manual endian swap is required for devices on big
endian machines with 32-bit accesses.
For both access sizes and machine endians the QEMU memory API can do the right thing
automatically: all that is needed is to set .impl.min_access_size to 2 to declare that
the dp8393x implements 16-bit registers.
Normally .impl.max_access_size should also be set to 2, however that doesn't quite
work in this case since the register stride is specified using a (dynamic) it_shift
property which is applied during the MMIO access itself. The effect of this is that
for a 32-bit access the memory API performs 2 x 16-bit accesses, but the use of
it_shift within the MMIO access itself causes the register value to be repeated in both
the top 16-bits and bottom 16-bits. The Linux jazzsonic driver expects the stride to be
zero-extended up to access size and therefore fails to correctly detect the dp8393x
device due to the extra data in the top 16-bits.
The solution here is to remove .impl.max_access_size so that the memory API will
correctly zero-extend the 16-bit registers to the access size up to and including
it_shift. Since it_shift is never greater than 2 than this will always do the right
thing for both 16-bit and 32-bit accesses regardless of the machine endian, allowing
the manual endian swap code to be removed.

Instead of accessing N registers via a single address_space API
call using a temporary buffer (stored in the device state) and
updating each register, move the address_space call in the
register put/get. The load/store and word size checks are moved
to put/get too. This simplifies a bit, making the code easier
to read.

Per the DP83932C datasheet from July 1995:
4.0 SONIC Registers
4.1 THE CAM UNIT
The Content Addressable Memory (CAM) consists of sixteen
48-bit entries for complete address filtering of network
packets. Each entry corresponds to a 48-bit destination
address that is user programmable and can contain any
combination of Multicast or Physical addresses. Each entry
is partitioned into three 16-bit CAM cells accessible
through CAM Address Ports (CAP 2, CAP 1 and CAP 0) with
CAP0 corresponding to the least significant 16 bits of
the Destination Address and CAP2 corresponding to the
most significant bits.
Store the CAM registers as 16-bit as it simplifies the code.
Having now the CAM registers as arrays of 3 uint16_t, we can avoid
using the VMSTATE_BUFFER_UNSAFE macro by using VMSTATE_UINT16_2DARRAY
which is more appropriate. This breaks the migration stream however.

Currently when a LOAD CAM command is executed the entries are loaded into the
CAM from memory in order which is incorrect. According to the datasheet the
first entry in the CAM descriptor is the entry index which means that each
descriptor may update any single entry in the CAM rather than the Nth entry.
Decode the CAM entry index and use it store the descriptor in the appropriate
slot in the CAM. This fixes the issue where the MacOS toolbox loads a single
CAM descriptor into the final slot in order to perform a loopback test which
must succeed before the Ethernet port is enabled.

This is because the host_to_mips_errno[] uses errno as index,
for example:
static const uint16_t host_to_mips_errno[] = {
[ENAMETOOLONG] = 91,
...
and Haiku defines [*] ENAMETOOLONG as:
12 /* Error baselines */
13 #define B_GENERAL_ERROR_BASE INT_MIN
..
22 #define B_STORAGE_ERROR_BASE (B_GENERAL_ERROR_BASE + 0x6000)
...
106 #define B_NAME_TOO_LONG (B_STORAGE_ERROR_BASE + 4)
...
211 #define ENAMETOOLONG B_TO_POSIX_ERROR(B_NAME_TOO_LONG)
so the array ends up beeing indeed too big.
Since POSIX errno can't be use as indexes on Haiku,
rewrite errno_mips() using a switch statement.
