scripts/gdb: port to python3 / gdb7.7
I tried to use these scripts in an ubuntu 14.04 host (gdb 7.7 compiled against python 3.3) but there were several errors. I believe this patch fixes these issues so that the commands now work (I tested lx-symbols, lx-dmesg, lx-lsmod). Main issues that needed to be resolved: * In python 2 iterators have a "next()" method. In python 3 it is __next__() instead (so let's just add both). * In older python versions there was an implicit conversion in object.__format__() (used when an object is in string.format()) where it was converting the object to str first and then calling str's __format__(). This has now been removed so we must explicitly convert to str the objects for which we need to keep this behavior. * In dmesg.py: in python 3 log_buf is now a "memoryview" object which needs to be converted to a string in order to use string methods like "splitlines()". Luckily memoryview exists in python 2.7.6 as well, so we can convert log_buf to memoryview and use the same code in both python 2 and python 3. This version of the patch has now been tested with gdb 7.7 and both python 3.4 and python 2.7.6 (I think asking for at least python 2.7.6 is a reasonable requirement instead of complicating the code with version checks etc).
