New port: security/peda: Python-based GDB extension for exploit development and debugging

PEDA (Python Exploit Development Assistance for GDB) is a plugin for GDB.
It extends GDB with a colorful text-based UI making it easier to work with
the debugger.

Note that PEDA requires that GDB is compiled with Python support.

Its key features are:

- Enhance the display of GDB: colorize and display disassembly codes,
  registers, memory information during debugging.
- Add commands to support debugging and exploit development.

+Now that PEDA is installed it can be used with gdb(1).
+
+Run the following command in the gdb prompt to load the plugin:
+
+```
+source %%LIBEXECDIR%%/%%UTILITY_NAME%%
+```
+
+In order to load PEDA automatically on gdb(1) launch add the line mentioned
+above to ~/.gdbinit:
+
+```
+echo "source %%LIBEXECDIR%%/%%UTILITY_NAME%%" >> ~/.gdbinit
+```
+
+Keep in mind that PEDA requires at least GDB 7.0 to work.
