Behdad Esfahbod c986ca15a6 Improve overflow avoidance
Better fix for 480406cd3e
This way we behave the same on 32bit and 64bit archs.

fix FDSelect fuzzing bug (#1539)
Rewrote struct FDSelect3_4.ranges as ArrayOf
Updated FDSelect3_4::sanitize () to call ranges.sanitize ()
nRanges now a function to return a reference to ranges.len

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 b5c12b9f4d print() is a function in Python 3 (#1520) 2018-12-30 15:37:28 +03:30
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...

* uncamelized non-struct types OpCode etc

* add byte_str_t copy ctor

* test

* test2

* undo tests

* fix bot failure

* undo the previous change

* fixed tabs, added inline

* Revert "fixed tabs, added inline"

This reverts commit 21163c30e9.

* fix tabs
