fb6feaf082 Improve correspondence with Python errors and console behavior
Compiler and command-line error messages now reflect their Python counterparts.
E.g. where Python emits a `SyntaxError`, so does Hy; same for `TypeError`s.
Multiple tests have been added that check the format and type of raised
exceptions over varying command-line invocations (e.g. interactive and not).

A new exception type for `require` errors was added so that they can be treated
like normal run-time errors and not compiler errors.

The Hy REPL has been further refactored to better match the class-structured
API.  Now, different error types are handled separately and leverage more base
class-provided functionality.

Closes hylang/hy#1486.

86fda31ab1 Move compilation and parsing functions out of importer.py
Functions and variables relating to compilation and parsing have been moved to
`compiler.py` and `lex/__init__.py`, respectively.  Those functions are
  - `hy_parse` from `hy.importer` to `hy.lex`
  - `hy_eval`, `ast_compile`, and `calling_module` from `hy.importer` to
  `hy.compiler`

Closes hylang/hy#1695.

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.

87a5b117a1 Implement new importer using PEP-302 semantics
Python 3.x is patched in a way that integrates `.hy` source files into
Pythons default `importlib` machinery.  In Python 2.7, a PEP-302 "importer"
and "loader" is implemented according to the standard `import` logic (via
`pkgutil` and later pure-Python `imp` package code).

In both cases, the entry-point for the loaders is through `sys.path_hooks` only.
As well, the import semantics have been updated all throughout to utilize
`importlib` and follow aspects of PEP-420.  This, along with some light
patches, should allow for basic use of `runpy`, `py_compile` and `reload`.

In all cases, if a `.hy` file is shadowed by a `.py`, Hy will silently use
`.hy`.

3204a9e8a3 Streamline auto-promotion and position spoofing
Auto-promotion now occurs in only two cases: when we start the compiler and when we expand a macro. It's fully recursive so even a non-model nested in a model will be promoted.

This change fixes some regressions induced by the stricter type checks of the pattern-matching compiler.
