IDAPython >7.4 compatibility issues

[slayermaster]

d.hookSeg() will not finish and running python script window wont go away until pressing cancel.

IDA Pro 7.7

Output shows AttributeError: 'idainfo' object has no attribute 'get_maxEA' when breakpoint met.

[slayermaster]

d.hookSeg() stuck was probably because the app has many calls, so it takes time to complete.
The get_maxEA error is from IDAPython >7.4 , can be fixed by changing get_inf_structure().get_maxEA() into ida_ida.inf_get_max_ea(). Same for minEA.

d.code_discovery = True however would not work, just hangs after the modifications above.

  a = Auto().win_code_discovery()
