e9ccfdd91d hmp: Add 'one-insn-per-tb' command equivalent to 'singlestep'
The 'singlestep' HMP command is confusing, because it doesn't
actually have anything to do with single-stepping the CPU.  What it
does do is force TCG emulation to put one guest instruction in each
TB, which can be useful in some situations.

Create a new HMP command  'one-insn-per-tb', so we can document that
'singlestep' is just a deprecated synonym for it, and eventually
perhaps drop it.

We aren't obliged to do deprecate-and-drop for HMP commands,
but it's easy enough to do so, so we do.

e726acd5b8 accel/tcg: Report one-insn-per-tb in 'info jit', not 'info status'
Currently we report whether the TCG accelerator is in
'one-insn-per-tb' mode in the 'info status' output.  This is a pretty
minor piece of TCG specific information, and we want to deprecate the
'singlestep' field of the associated QMP command.  Move the
'one-insn-per-tb' reporting to 'info jit'.

We don't need a deprecate-and-drop period for this because the
HMP interface has no stability guarantees.

93cbd6c91d softmmu: Don't use 'singlestep' global in QMP and HMP commands
The HMP 'singlestep' command, the QMP 'query-status' command and the
HMP 'info status' command (which is just wrapping the QMP command
implementation) look at the 'singlestep' global variable. Make them
access the new TCG accelerator 'one-insn-per-tb' property instead.

This leaves the HMP and QMP command/field names and output strings
unchanged; we will clean that up later.
