1b7dfd2839 Make HyKeyword a first class objects
HyKeywords are no longer an instances of string with a particular
prefix, but a completely separate object.

This means keywords no longer trip isinstance str checks, adding a
little bit of type safety to the compiler.

It also means that HyKeywords evaluate to themselves.

Closes #1352

4073c78069 Add -E support for Hy REPL
This commit adds -E support for Hy. Similar to Python, hy will ignore
all PYTHON* environment variables, e.g. PYTHONPATH and PYTHONHOME,
that might be set.

b27cdfed69 Fix defclass construction
Python Class AST expects a body which is a list of ast.Expr. Force
every entry to be stored as a statement. This means we'll preserve
print statements.

Python also doesn't construct docstrings in classes by setting a
__doc__ attribute, it does it by inspecting the first ast.Expr node of
the class. But this means we can remove the special handler for it.

84e1c65bcd Improve checks inside defclass
We need to make sure we're looking at HyExpression when trying to
determine if we're rewriting an __init__ expression.

d501d4d806 Mangle symbols at compile-time instead of parse-time
This means that a HySymbol remembers its original name. That is, `a-b` and `a_b` are different symbols although `(setv a-b 1)` and `(setv a_b 1)` set the same variable (namely, `a_b`).

Most of the edits in this commit are to switch underscores to hyphens in places where mangling hasn't happened yet.

I removed some lexer tests since the lexer no longer does any mangling.

4c38e2c9dd Rename reader macros to "sharp macros" (#1282)
They're not actually reader macros, since their arguments are parsed s-expressions, like a regular macro, not pre-parsed source text.

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.

5eb928356a Overhaul semantics of binary operators (#1261)
I've added shadow versions of many operators that didn't have one. And, I've changed the behavior of various binary operators with more or fewer than 2 arguments to make the shadow and real versions more consistent and to make the behavior more logical in either case. For details, see the additions to NEWS and the new file tests/native_tests/operators.hy, which simultaneously tests shadow and real operators.

Although there are a lot of changes, I've put them all in one commit because they're interdependent.

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.

7c203abe4d Fix bug with unset __name__ of one-line functions
The bug was a regression that I introduced in #1228.

I've created a new special form named `fn*` that works like the old `fn` (that is, it always creates a `FunctionDef`). Since this is intended only for internal use, like `with*`, I haven't documented it.
