1. Change --break input option format. Too much typing by taking decimal address. Change to hexadecimal input.
2. Allow ROM break point to continue to execution. The original ROM break point just replace instruction in ROM break point address with emul_op M68K_EMUL_BREAK. This just halts emulation right at the break point. The patch is less invasive than the original approach. It allows emulation to continue to run by pressing 'x' to exit from cxmon.
3. Add option --loadbreak which load break point from file before emulation start.

To enter break point, you need to run a m68k program in Macintosh guest OS. The program
executes a new emul_op instruction 0x7138. The program will be provided
in cxmon/utils folder in a separate commit. Once emulation is suspended,
you can enter below new cxmon command to manipluate break points:
ba [address] Add a break point
br [breakpoints#] Remove a break point. If # is 0, remove all break points.
bd [breakpoints#] Disable a break point. If # is 0, disable all break points.
be [breakpoints#] Enable a break point. If # is 0, enable all break points.
bi List all break points
bs "file" Save all break points to a file
bl "file" Load break points from a file
Once emulation PC reach break point address, it automatically suspends
and traps into cxmon.

Remove autotools generated files from the repository, provide a 'bootstrap'
script for regenerating them, and update the configure.ac and Makefile.am
files.
