a8fe95c5b6 Update test_preprocessor_exceptions
This test has been passing since b023ebd0b5, so I removed the xfail. I also rewrote the test to use pytest.raises.

87aced2370 Don't let HyExpression etc. inherit from HyList
This means the compiler no longer allows e.g. `(fn (x) ...)` in place of `(fn [x] ...)`.

c1a487cdf7 Move logic from macroexpand_1 to macroexpand
By ending macro-expansion immediately when appropriate, this change fixes a bug arising from the fact that NaN != NaN.

7bf2901364 Ban (except)
It's rarely useful, because it catches all exceptions, but it doesn't let you do anything other than return `None`. You can still get the same effect with `(except [])`.

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.

f332ad2eae Improve testing of hy2py
Instead of just checking that hy2py outputs a nonempty string and doesn't crash, we check that a hy2py-generated Python program works the same as the original Hy program.

This test suggests my plan to make hy2py output real Python has succeeded, so I updated NEWS accordingly.

291847af15 Make HyKeyword constructor consistent
The colon is now only part of its string representation and no longer
accepted as part of the constructor:

  :foobar == HyKeyword("foobar")

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

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.

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.
