monitor: Create monitor-internal.h with common definitions

Before we can split monitor/misc.c, we need to create a header file that
contains the common definitions that will be used by multiple source
files.

For a start, add the type definitions for Monitor, MonitorHMP and
MonitorQMP and their dependencies. We'll add functions as needed when
splitting monitor/misc.c.

- * Supported types:
- *
- * 'F'          filename
- * 'B'          block device name
- * 's'          string (accept optional quote)
- * 'S'          it just appends the rest of the string (accept optional quote)
- * 'O'          option string of the form NAME=VALUE,...
- *              parsed according to QemuOptsList given by its name
- *              Example: 'device:O' uses qemu_device_opts.
- *              Restriction: only lists with empty desc are supported
- *              TODO lift the restriction
- * 'i'          32 bit integer
- * 'l'          target long (32 or 64 bit)
- * 'M'          Non-negative target long (32 or 64 bit), in user mode the
- *              value is multiplied by 2^20 (think Mebibyte)
- * 'o'          octets (aka bytes)
- *              user mode accepts an optional E, e, P, p, T, t, G, g, M, m,
- *              K, k suffix, which multiplies the value by 2^60 for suffixes E
- *              and e, 2^50 for suffixes P and p, 2^40 for suffixes T and t,
- *              2^30 for suffixes G and g, 2^20 for M and m, 2^10 for K and k
- * 'T'          double
- *              user mode accepts an optional ms, us, ns suffix,
- *              which divides the value by 1e3, 1e6, 1e9, respectively
- * '/'          optional gdb-like print format (like "/10x")
- *
- * '?'          optional type (for all types, except '/')
- * '.'          other form of optional type (for 'i' and 'l')
- * 'b'          boolean
- *              user mode accepts "on" or "off"
- * '-'          optional parameter (eg. '-f')
