Ebrahim Byagowi 5110f3da9a
Add an initial .clang-format config 
There are things can be improved on clang-format side I guess before
the full assertion, but is the best we can get for now I guess.

cclauss 26c5b54fb0 CircleCI: Test for Python 3 syntax errors and undefined names (#1522) 
Catch missing imports and errors like #1520 and #1521

__E901,E999,F821,F822,F823__ are the "_showstopper_" [flake8](http://flake8.pycqa.org) issues that can halt the runtime with a SyntaxError, NameError, etc. Most other flake8 issues are merely "style violations" -- useful for readability but they do not effect runtime safety.
* F821: undefined name `name`
* F822: undefined name `name` in `__all__`
* F823: local variable name referenced before assignment
* E901: SyntaxError or IndentationError
* E999: SyntaxError -- failed to compile a file into an Abstract Syntax Tree

cclauss f4da28b1f1 Python 3 fixes to gen-os2-unicode-ranges.py (#1521) 
In Python 3, __reload()__ was moved and __sys.setdefaultencoding()__ because the default is already utf-8.  Also __Error()__ is an _undefined name_ and __Exception()__ creates a generic exception.

Behdad Esfahbod fa333e34d6 [vector] Remove static_array 
Was good idea, but with C++ types with constructor/destructor, was getting in
the way as compiler was destructing those items where it was not desired.
Since C++ does not allow zero-sized arrays, just remove it...
