Brandon T. Willard 010986e8ca Implement minimal macro namespacing and add tests
This commit adds just enough namespacing to resolve a macro first in the macro's
defining module's namespace (i.e. the module assigned to the `HyASTCompiler`),
then in the namespace/module it's evaluated in.  Namespacing is accomplished by
adding a `module` attribute to `HySymbol`, so that `HyExpression`s can be
checked for this definition namespace attribute and their car symbol resolved
per the above.

As well, a couple tests have been added that cover
- the loading of module-level macros
  - e.g. that only macros defined in the `require`d module are added
- the AST generated for `require`
  - using macros loaded from modules imported via bytecode
- the non-local macro namespace resolution described above
  - a `require`d macro that uses a macro `require` exclusively in its
    module-level namespace
- and that (second-degree `require`d) macros can reference variables within
  their module-level namespaces.

Closes hylang/hy#1268, closes hylang/hy#1650, closes hylang/hy#1416.
