Skylint: improve the naming conventions checker
Changes in behavior:
* Local variables are also allowed to be UPPER_SNAKE_CASE.
Upper case means that they're constants but this is not checked yet.
* Providers are required to be UpperCamelCase. A variable FooBar
is considered a provider if it appears in an assignment of the form
"FooBar = provider(...)"
* Shadowing of builtins (e.g. "True = False", "def fail()") is
not allowed
* The single-letter variable names 'O', 'l', 'I' are disallowed
since they're easy to confuse
* Multi-underscore names ('__', '___', etc.) are disallowed
* Single-underscore names may only be written to, as in
a, _ = tuple
They may not be read, as in "f(_)".
In the process, I also moved some code from UsageChecker to
AstVisitorWithNameResolution to prevent duplication in
NamingConventionsChecker.
