At init, qemu_chr_reset is always called with initial_reset_issued set to 1.
So checking for it to be set is not necessary.

The goal is eventually to get rid of all cpu_T register usage and to use
just short-lived tmp/tmp2 registers. This patch converts all the places where
cpu_T was used in the Thumb code and replaces it with explicit TCG register
allocation.

The neon_trn_u8, neon_trn_u16, neon_unzip_u8, neon_zip_u8 and neon_zip_u16
helpers used fixed registers to return values. This patch replaces that with
TCG code, so T0/T1 is no longer directly used by the helper functions.
Bugs in the gen_neon_unzip register load code were also fixed.

Currently each read/write of ARM register involves a LD/ST TCG operation. This
patch uses TCG memory-backed registers to represent the ARM register set. With
memory-backed registers the LD/ST operations are transparently generated by TCG
and host registers could be used to optimize the generated code.

When the synchronous read and write functions were dropped, they were replaced
by generic emulation functions. Unfortunately, these emulation functions don't
provide the same semantics as the original functions did.
The original bdrv_read would mean that we read some data synchronously and that
we won't be interrupted during this read. The latter assumption is no longer
true with the emulation function which needs to use qemu_aio_poll and therefore
allows the callback of any other concurrent AIO request to be run during the
read. Which in turn means that (meta)data read earlier could have changed and
be invalid now. qcow2 is not prepared to work in this way and it's just scary
how many places there are where other requests could run.
I'm not sure yet where exactly it breaks, but you'll see breakage with virtio
on qcow2 with a backing file. Providing synchronous functions again fixes the
problem for me.

Currently, suboptions (i.e. something like file=file for -drive) are rendered
as @code, so we're losing any @var highlighting in the man pages.
Replace them by @option, so that you actually can see what is a placeholder and
what is meant verbatim.

For NICs, net_init_client() returns the index into the NICInfo table.
qemu_opts_foreach() interprets non-zero as an error return an stops
iterating over the options.
So, if you have more than one '-net nic' on the command line, subsequent
'-net' options do not get processed.
Fix this by making net_client_init() only return non-zero if
net_init_client() returns an error.

Allow net clients to be created which are not connected to any vlan.
This is needed by Gerd in order to allow adding -device nic, where
the absence of a vlan parameter will not imply vlan=0. Also needed
to allow adding a -netdevice option which doesn't connect the backend
to a vlan.

Just use the name field instead since we now use the id paramater as
the name, if supplied. Only implication with this change is that if
id is not supplied, the value of the name paramater is used as an
id.
