Convert stderr message calling error_get_pretty() to error_report()

Convert stderr messages calling error_get_pretty()
to error_report().

Timestamp is prepended by -msg timstamp option with it.

Per Markus's comment below, A conversion from fprintf() to
error_report() is always an improvement, regardless of
error_get_pretty().

http://marc.info/?l=qemu-devel&m=137513283408601&w=2

But, it is not reasonable to convert them at one time
because fprintf() is used everwhere in qemu.

So, it should be done step by step with avoiding regression.

OptsVisitor: introduce basic list modes

We're going to need more state while processing a list of repeated
options. This change eliminates "repeated_opts_first" and adds a new state
variable:

  list_mode       repeated_opts  repeated_opts_first
  --------------  -------------  -------------------
  LM_NONE         NULL           false
  LM_STARTED      non-NULL       true
  LM_IN_PROGRESS  non-NULL       false

Additionally, it is documented that lookup_scalar() and processed(), both
called by opts_type_XXX(), are invalid in LM_STARTED -- generated qapi
code calls opts_next_list() to allocate the very first link before trying
to parse a scalar into it. List mode restrictions are expressed in
positive / inclusive form.

OptsVisitor: introduce list modes for interval flattening

The new modes are equal-rank, exclusive alternatives of LM_IN_PROGRESS.
Teach opts_next_list(), opts_type_int() and opts_type_uint64() to handle
them.

Also enumerate explicitly what functions are valid to call in what modes:
- opts_next_list() is valid to call while flattening a range,
- opts_end_list(): ditto,
- lookup_scalar() is invalid to call during flattening; generated qapi
  traversal code must continue asking for the same kind of signed/unsigned
  list element until the interval is fully flattened,
- processed(): ditto.

List mode restrictions are always formulated in positive / inclusive
sense. The restrictions for lookup_scalar() and processed() are
automatically satisfied by current qapi traversals if the schema to build
is compatible with OptsVisitor.

The new list modes are not entered yet.

OptsVisitor: don't try to flatten overlong integer ranges

Prevent mistyped command line options from incurring high memory and CPU
usage at startup. 64K elements in a range should be enough for everyone
(TM).

monitor: print the invalid char in error message

It's more friendly to print which char is invalid to user, especially
when user tries to input a float value and expect the monitor to round
it to int. Since we don't round float number when we look for a integer,
telling which char is invalid is less confusing.
