fa54884131 Fix unit tests when run with PYTHONDONTWRITEBYTECODE
When set, it will conflict with any tests that generate bytecode
because they don't expect it to be set.

Fixable by sanitize the environment before forking, but we can't do
anything about import tests.

This is a pipenv default, and possibly a sane flag to set while doing
Hy development, so lets not let it be a hazard for developers to trip
over.

2b11b9be20 Automatically read and write bytecode
Importing or executing a Hy file now loads the byte-compiled version if it exists and is up to date, and if not, the source is byte-compiled after it's parsed.

This change can speed up Hy a lot. Here are some examples comparing run times of the current master (491b474e) to this commit, on my laptop with Python 3.6:

- `nosetests --exclude='test_bin'` goes from 3.8 s to 0.7 s (a 5-fold speedup)
- `hy -c '(print "hello world")` goes from 0.47 s to 0.20 s (a 2-fold speedup)
- Rogue TV's startup goes from 3.6 s to 0.4 s (a 9-fold speedup)

Accompanying changes include:

- `setup.py` now creates and installs bytecode for `hy.core`, `hy.contrib`, and `hy.extra`.
- The `hyc` command under Python 3 now creates bytecode in `__pycache__`, as usual for Python 3, instead of putting the `.pyc` right next to the source file like Python 2 does.

I've removed a test of `hy.extra.anaphoric.a-if` that triggers #1268 when the test file is byte-compiled and then hits some weird `macroexpand` bug or something when I try to work around that—Nose crashes when trying to produce an error message, and I can't seem to replicate the bug without Nose.

18acfe6495 Revert the extension of with-decorator to setv
This is no longer necessary now that `defn` always produces a `FunctionDef`.

To compensate, I've made small edits to two contrib modules and reverted a small test change.

e4a7b317e1 Make fn work like lambda and remove lambda (#1228)
* with-decorator: Allow a `setv` form as the form to be decorated

This feature is of dubious value by itself, but it's necessary to allow `defn` to create a lambda instead of a `def`.

* Make `fn` work the same as `lambda`

That is, allow it to generate a `lambda` instead of a `def` statement if the function body is just an expression.

I've removed two uses of with_decorator in hy.compiler because they'd require adding another case to HyASTCompiler.compile_decorate_expression and they have no ultimate effect, anyway.

In a few tests, I've added a meaningless statement in `fn` bodies to force generation of a `def`.

I've removed `test_fn_compiler_empty_function` rather than rewrite it because it seems like a pain to maintain and not very useful.

* Remove `lambda`, now that `fn` does the same thing

hy/compiler.py: import only handles HySymbol and HyList, bail on others
When (import) encounters anything but a HySymbol or HyList, raise an
exception, as that is not valid in Hy. Previously, anything other than a
HySymbol or HyList was simply ignored, turning that particular import
into a no-op, which was both wrong and confusing.

269da19d76 Make macros module-specific.
A macro is available in the module where it was defined and
in any module that does a require of the defining module.
Only macros defined in hy.core are globally available.
