[patch] Add watchpoint support to (and add supportingmethods to python-breakpoint.c)

Something that has been on my mind for awhile is that does not handle watchpoints very well. I like watchpoints, and use them all the time! So I propose this patch:

This patch adds watchpoint support to the command. I added two new methods to python_breakpoint.c to achieve this goal. As watchpoints only seemed to be represented as an expression, then the bppy_get_expression function had to be included to interrogate the expression behind the gdb breakpoint. To differentiate between the types of watchpoint (and other breakpoints ...), I added a bppy_get_type function along with supporting constants. Included are documentation entries also. I elected not to include catchpoint support as catchpoint "type" seems to be hidden behind the struct bp_ops function pointers in the breakpoint struct. If there is another way to differentiate between the different catchpoints by type, I'd be happy to add them into this patch, too.
