Georgy Komarov d977761e76 addons: Reduce memory consumption ()
* addons: Reduce memory consumption

Parse dump files incrementaly using ElementTree.iterparse. Clean unused
resources during parsing.  This method is explained in following
article: https://www.ibm.com/developerworks/xml/library/x-hiperfparse/

Memory consumption was reduced about 30% (measured with mprof),
execution time increased about 5% (measured with time utility).
More description available in PR.

* Switch to lxml and update iterparse routines

Use lxml module instead default xml.etree. Lxml provides convenient
wrappers around iterparse method that accepts `tag` argument. That
easer incremental parsing routines to select specific tags from roottree
like `dump` and `dumps`.

Element.clear() method was replaced by `lxml_clean` because lxml
keeps additional information to nodes that should be removed.

Added note about large consumption RAM on large dump files.
This commit doesn't solve this problem completely, but provides a way
to improve current parser to add incremental Configuration serialization
later.

* Working on iterative parser

* Added iterative Configurations parser

* fix

* Fix varlist iteration

* make sure that standards node was loaded

addons: Change shebang to use Python 3 instead of Python 2 ()
Use Python 3 instead of Python 2 if addons are executed directly.
Running cert.py and misra.py against test/cfg/std.c.dump shows that
Python 3 needs only half the time compared to Python 2. I have tested
it repeatedly and the results are always the same. This is no surprise
at all. The memory footprint is very likely also significantly better
but i have not tested it.

IOBYTE e5220bdf0c make ellipsis ... a single token ()
* make ellipsis ... a single token

Using cppcheck -E to preprocess code with ellipsis produces output that
can't be compiled because ... is split into 3 tokens.

* try to fix addon

Oliver Stöneberg 13cf982b77 some small *.py script cleanup ()
* added CLion project folder to .gitignore

* adjusted project name in CMakeLists.txt

* avoid warning when compiling "Debug" with Visual Studio via CMake

There was a GCC-style compiler flag in the common flags in compileroptions.cmake which caused the following warning:
cl : Command line warning D9002 : ignoring unknown option '-O0'

* compileroptions.cmake: restored original formatting

* some small *.py script cleanups
