ida 7.7 sdk support

[thewolfram]

ida 7.7 sdk needs a flag in plugin_t class, which one we should use for this plugin?

#define PLUGIN_MOD  0x0001      ///< Plugin changes the database.
                                ///< IDA won't call the plugin if
                                ///< the processor module prohibited any changes.

#define PLUGIN_DRAW 0x0002 ///< IDA should redraw everything after calling the plugin.
#define PLUGIN_SEG 0x0004 ///< Plugin may be applied only if the current address belongs to a segment

#define PLUGIN_UNL  0x0008      ///< Unload the plugin immediately after calling 'run'.
                                ///< This flag may be set anytime.
                                ///< The kernel checks it after each call to 'run'
                                ///< The main purpose of this flag is to ease
                                ///< the debugging of new plugins.

#define PLUGIN_HIDE 0x0010      ///< Plugin should not appear in the Edit, Plugins menu.
                                ///< This flag is checked at the start.

#define PLUGIN_DBG  0x0020      ///< A debugger plugin. init() should put
                                ///< the address of ::debugger_t to dbg.

#define PLUGIN_PROC 0x0040      ///< Load plugin when a processor module is loaded. (and keep it
                                ///< until the processor module is unloaded)

#define PLUGIN_FIX 0x0080 ///< Load plugin when IDA starts and keep it in the memory until IDA stops

#define PLUGIN_MULTI    0x0100  ///< The plugin can work with multiple idbs in parallel.
                                ///< init() returns a pointer to a plugmod_t object
                                ///< run/term functions are not used.
                                ///< Virtual functions of plugmod_t are used instead.

#define PLUGIN_SCRIPTED 0x8000  ///< Scripted plugin. Should not be used by plugins,
                                ///< the kernel sets it automatically.
