	* nec4102rom.c : New file implements rom monitor adapter for
        nec-vr4102 board. This board hosts the vr4111 chip. This file
        required extenstions to the monitor_ops structure, hooks for wiat
        filter, new flags. This version does not support more than one
        breakpoint and resuming after a breakpoint in 16 bit mode is
        completely disfunctional.  * monitor.h : Defined additional hooks
        for dmpregs, confinuer_hooks and wait_filter. These additions
        require that all rom monitor interfaces be recoded to to
        initializa monitor ops using assignments rather than static
        structure initialization.  Added new bits to flags
        MO_EXACT_DUMPADDR, MO_HAS_BLOCKWRITES
        * monitor.c (RDEBUG): Conditional tracing throughout the file.
        (fromhex): Now recognized upper cse hex digits
        (monitor_printf_noecho):
        (monitor_readchar): Tracing interferes with input timing.
        (monitor_open): Register different memory write functions with
        dcache_init if MO_HAS_BLOCKWRITES.
        (flush_monior_dcache): Added as an additional utilty.
        (monitor-resume): Call continue hook if one has been supplied.
        (monitor_wait_filter): New function Factored out of monitor wait
        and used if alternate wait-filter has not been provided.
        (monitor_wait): call alternate wait filter if provided.  Call
        monitor_dump_regs, a new function factored out from inline code.
        (monitor_dump_block): A new function used as a utility when
        monitors must dump several blocks of registers using different
        commands.
        (monitor_dump_regs): Call alternate function if provided. Uses new
        hook in monitor.h.
        (monitor_write_memory): Engage previouly added hook
        MO_FILL_USES_ADDR.
        (monitor_write_even_block): new function supports writing long
        blocks of 4byte words.
        (longlongendswap): new internal function
        (monitor_write_memory_longlongs): new function writes large blocks
        using command to enter a long long.
        (monitor_write-memory_block): new Function figures out which block
        mod to use.
        (monitor_read_memory): Can now handle dump formats in which the bytes
        preceeding the requested data is not printed.
	* monitor.h: Added new fields to the structure
