The get_maint_bp_addr procedure will be shared by other test suite, so move it to gdb-utils.exp. Following Andrew's suggestion, I renamed get_maint_bp_addr to gdb_get_bp_addr, since it would have handled normal breakpoints in addition to the internal ones. Note that there is still room for improvement in this procedure, which I indicated in comments nearby.

# Parameter:
|

# The parameter "num" indicates the number of the breakpoint to get.

# Note that *currently* this parameter must be an integer value.

# E.g., -1 means that we're gonna get the first internal breakpoint;

# Return:

# First address for a particular breakpoint.

# TODO:
|
|
# It would be nice if this procedure could accept floating point value.
