At the moment QEMU exits if trace point is not defined which makes
a developer life harder if he has to switch between branches with
different traces implemented.
This replaces error+exit wit WARNING if the tracepoint does not exist or
not traceable.

Extract the pid field from the trace record and print it.
Change the trace record tuple from:
(event_num, timestamp, arg1, ..., arg6)
to:
(event_num, timestamp, pid, arg1, ..., arg6)
Trace event methods now support 3 prototypes:
1. <event-name>(arg1, arg2, arg3)
2. <event-name>(timestamp, arg1, arg2, arg3)
3. <event-name>(timestamp, pid, arg1, arg2, arg3)
Existing script continue to work without changes, they only know about
prototypes 1 and 2.

It is useful to know the QEMU process ID when working with traces from
multiple VMs. Although the trace filename may contain the pid, tools
that aggregate traces or even trace globally need somewhere to record
the pid.
There is a reserved field in the trace event header struct that we can
use.
It is not necessary to bump the simpletrace file format version number
because it has already been incremented for the QEMU 2.1 release cycle
in commit "trace: [simple] Bump up log version number".

The wrapper functions _t_gen_mov_TN_env and _t_gen_mov_env_TN are only
used via their accompanying non-underscore macros. The check they add
on offset is thus pointless, since the compiler will complain if the
struct field passed to the macro is not part of the struct. Remove the
functions and make the macros directly expand to the appropriate
tcg_gen_{ld,st}_tl calls.
This conveniently avoids a warning due to _t_gen_mov_TN_env() being
unused.

Remove the t_gen_mov_TN_reg and t_gen_mov_reg_TN wrappers: the
latter is completely unused, and the former only used in a few
places (which are thus inconsistent with the rest of the decoder
which directly accesses cpu_R[]).

This is an intermediate step to bring TCX in line with CG3.
Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
CC: Andreas Färber <afaerber@suse.de>
The case statements in the CG3 read and write register routines have a maximum
value of CG3_REG_SIZE, so if a value were written to this offset then it
would overflow the register array.
Currently this cannot be exploited since the MemoryRegion restricts accesses
to the range 0 ... CG3_REG_SIZE - 1, but it seems worth clarifying this for
future review and/or static analysis.
