hw: ccid-card-emulated: cleanup resource when realize in error path
The emulated_realize method was changed so that it jumps to a cleanup
label to de-initialize state upon error. This change failed to ensure
the success path exited the method before this point though. So the
mutexes are always destroyed even in normal operation. The result is
as crashtastic as expected:
$ qemu-system-x86_64 -usb -device usb-ccid,id=ccid0 -device ccid-card-emulated,backend=nss-emulated,id=smartcard0,bus=ccid0.0
qemu-system-x86_64: util/qemu-thread-posix.c:64: qemu_mutex_lock_impl: Assertion `mutex->initialized' failed.
Aborted (core dumped)

fw_cfg_reboot() gets option parameter "reboot-timeout" with
qemu_opt_get(), then converts it to an integer by hand. It neglects to
check that conversion for errors, and fails to reject negative values.
Positive values above the limit get reported and replaced by the limit.
This patch checks for conversion errors properly, and reject all values
outside 0...0xffff.

fw_cfg_bootsplash() gets option parameter "splash-time"
with qemu_opt_get(), then converts it to an integer by hand.
It neglects to check that conversion for errors. This is
needlessly complicated and error-prone. But as "splash-time
not specified" is not the same as "splash-time=T" for any T,
we need use qemu_opt_get() to check if splash time exists.
This patch also make the qemu exit when finding or loading
splash file failed.

The dmg file has many tables which describe: "start from sector XXX to
sector XXX, the compression method is XXX and where the compressed data
resides on".
Each sector in the expanded file should be covered by a table. The table
will describe the offset of compressed data (or raw depends on the type)
in the dmg.
For example:
[-----------The expanded file------------]
[---bzip table ---]/* zeros */[---zlib---]
^
| if we want to read this sector.
we will find bzip table which contains this sector, and get the
compressed data offset, read it from dmg, uncompress it, finally write to
expanded file.
If we skip zero chunk (table), some sector cannot find the table which
will cause search_chunk() return s->n_chunks, dmg_read_chunk() return -1
and finally causing dmg_co_preadv() return EIO.
See:
[-----------The expanded file------------]
[---bzip table ---]/* zeros */[---zlib---]
^
| if we want to read this sector.
Oops, we cannot find the table contains it...
In the original implementation, we don't have zero table. When we try to
read sector inside the zero chunk. We will get EIO, and skip reading.
After this patch, we treat zero chunk the same as ignore chunk, it will
directly write zero and avoid some sector may not find the table.
After this patch:
[-----------The expanded file------------]
[---bzip table ---][--zeros--][---zlib---]

This is a trivial patch to fix a wrong value for block terminator.
The old value was 0x7fffffff which is wrong. It was not affecting the
code because QEMU dmg block is not handling block terminator right now.
Neverthless, it should be fixed.

Add translation handlers for four logic MXU instructions.
It should be noted that there is an error in MXU documentation (dated
June 2017) regarding opcodes for this group of instructions. This was
confirmed by running tests on hardware, and also by looking up other
related public source trees (binutils, Android NDK). In initial MXU
patches to QEMU, opcodes for MXU logic instructions were created to
be in accordance with the MXU documentation, therefore the error from
was propagated. This patch corrects that, changing the involved code.
Besides that, as MXU was designed and implemented only for 32-bit
CPUs, corresponding preprosessor conditions were added around MXU
code, which allows more flexible implementation of MXU handlers.
