* Remove uses of `car` and `cdr` in /hy

* Remove uses of `car` and `cdr` in quote tests

* Remove `car` and `cdr` in favor of `first` and `rest`

I beefed up the documentation and tests for `first` and `rest` while I was at it.

I defined `car` and `cdr` in native_tests.cons so the tests read a bit more naturally.

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

ed930edefe Allow keyword args in method calls before the obj (#1167)
Unlike Python, Hy allows the programmer to intermingle positional and keyword arguments. This change removes an exception to that rule for method calls, in which the method callee always had to be the first thing after the method. Thus, `(.split :sep "o" "foo")` now compiles to `"foo".split(sep="o")` instead of `HyKeyword("sep").split("o", "foo")`.

I don't see why you'd put this in the standard library. I guess it could be useful for when you're maintaining a library and you want to change the name of a function or macro but keep the old name around for a while so people's code doesn't break immediately. But that's a pretty limited purpose.

* put back import getargspec

* Give better error message on failed macro expansion

Better error messages work most of the time. In cases where there are
parameters that aren't valid in Python, error message shown is rather
ugly. But this is better than no error messages at all and such
macros with strange parameter names are rather rare.

* fix flake8 errors

14fddbe6c3 Give require the same features as import (#1142)
Give `require` the same features as `import`

You can now do (require foo), (require [foo [a b c]]), (require [foo [*]]), and (require [foo :as bar]). The first and last forms get you macros named foo.a, foo.b, etc. or bar.a, bar.b, etc., respectively. The second form only gets the macros in the list.

Implements #1118 and perhaps partly addresses #277.

N.B. The new meaning of (require foo) will cause all existing code that uses macros to break. Simply replace these forms with (require [foo [*]]) to get your code working again.

There's a bit of a hack involved in the forms (require foo) or (require [foo :as bar]). When you call (foo.a ...) or (bar.a ...), Hy doesn't actually look inside modules. Instead, these (require ...) forms give the macros names that have periods in them, which happens to work fine with the way Hy finds and interprets macro calls.

* Make `require` syntax stricter and add tests

* Update documentation for `require`

* Documentation wording improvements

* Allow :as in `require` name lists

4b0296d257 Don't check the type of arguments to inc, odd?, etc.
This allows them to be used with numeric types that aren't built in, such as NumPy arrays. Because Python uses duck typing, there's generally no way to know in advance whether a given value will accept a given operator. Of course, things like `(inc "hello")` will still raise a `TypeError`, because so does `(+ "hello" 1)`.

8d2143177e Overhaul macros to allow macros to ref the Compiler
This allows macros to take a keyword dict containing useful things by
defining a keyword argument. This allows us to pass in new objects
which might be handy to have in macros.

This changeset refactors module_name to become `compiler`, so that we
can pass the compiler itself into the macros as `opts['compiler']`.

This allows the macro to both get the macro name
(`compiler.module_name`), as well as use the compiler to build AST.

In the future, this will enable us to create "super-macros" which return
AST, not HyAST, in order to manually create insane things from userland.

For userland macros (not `defmacro`) the core.language `macroexpand`
will go ahead and make a new compiler for you.

26f342d580 Teach apply about symbol mangling
apply now mangles strings and keywords according to the Hy mangling
rules (by using the same function, now imported from
hy.lex.parser). With this change, if the dict passed to apply has
keywords, strings or quoted symbols, they'll get mangled, to turn them
into proper keys.

This only works for the cases where the keys are directly in the apply
params. A previously deffed dict, or key through a variable will not be
mangled.

b92049d119 Allow defclass to have properties/method with built-in names
To allow classes to have methods that match built-in names, yet, still
disallow them outside of defclass, keep an internal state whether
builtins are allowed in the current context.

By default, this is false. But defclass will set it to True when it
compiles its body, and set it back to the previous value when it's done
with that. We need to set back to the previous value to allow nested
defclasses to work properly.

This closes #783.

b362943365 compiler: Fix the kw argument needs value exception

Guard against a few invalid list comprehension cases
Some valid-looking list comprehensions, such as (genexpr x []) can crash
Python 2.7. The AST we generate from these cannot be expressed in
Python, but were valid in Hy.

Added two guards to guard against this, so we raise an error instead of
crashing Python.

Closes #572, #591 and #634.

Mangle trailing bangs on symbols
Postfixing functions with a bang, like set!, get!, etc are relatively
common. However, those names are not valid in python, so in the name of
python interoperability, lets mangle them to set_bang and get_bang,
respectively.

Closes #536.

defclass reimagined
defclass now has a new syntax:

 (defclass Name [BaseList]
   [property value
    property value] ;; optional

   (defn method [self]
     self.property))

Anything after the optional property list (which will be translated to a
setv within the class context) will be added to the class body. This
allows one to have side effects and complex expressions within the class
definition.

As a side effect, defining methods is much more friendly now!

Closes #850.
