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.

a9763b34cf Fix sys.modules for failed imports in Python 2.7
Newly imported modules with compile and/or run-time errors were not being
removed from `sys.modules`.  This commit modifies the Python 2.7 loader so that
it follows Python's failed-initial-import logic and removes the module from
`sys.modules`.

c0c5c9c699 Make cmdline Hy process unknown filetypes as Hy source
This change a Hy-preferring `runhy` that is used by cmdline Hy.  Standard
`runpy` is still patched so that it can run `.hy` files, but the default
behaviour for unknown filetypes is preserved (i.e. assume they are Python
source).

Closes hylang/hy#1677.

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.

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.

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

ffd85bcc3e Fixes a long-standing bug in import under Python 3.3 and later.
Our MetaImporter was being inserted at the end of sys.meta_path.
For Python prior to 3.3, this was fine since sys.meta_path
was empty by default. As of the completion of PEP 302 in Py3.3 and
later, there are several importers registered by default. One of
these was trying (and failing) to import simple Hy modules,
resulting in a failure to import anything inside __init__.hy.

This change simply inserts the Hy-specific importer at the front
of the list.

This was noted in issue #620 (great catch @algernon)

Example:

Which outputs:

  (['test.hy'],)

875d5f2ff5 Rewrite the bootstrap macros in hy
This gets rid of the dichotomy between bootstrap.py and macros.hy,
by making both files hy modules.

I added some error checking to make the macros more resilient. The
biggest (user-visible) change is the change in cond, which now only
accepts lists as arguments. Tests updated accordingly.

Closes: #176 (whoops, no more bootstrap)

df7bb1d29a Provide bin scripts for both Windows and *nix
Summary: This update does away with the scripts in bin and changes
setup.py to use entry_points in cmdline.py for the scripts 'hy' and
'hyc'.

This fixes installing and running on Windows.

The tests are updated to run the 'hy' script produced by setup.py
and not from bin/hy. This is more correct and makes the tox tests
run on both Window and *nix.

For running hy or nosetests directly in the source tree, you do have
to run 'python setup.py develop' first. But since tox runs and builds
dists, all tox tests pass on all platforms.

Also, since there is no built-in readline on Windows, the setup.py
only on Windows requires 'pyreadline' as a replacement.

Switched from optparse to argparse in cmdline.py

Instead of trying to manually separate args meant for
hy from args meant for a hy script, this switches from
optparse to argparse for the CLI.

argparse automatically peels out args meant for hy and leaves
the rest, including the user hy script in options.args.

This fixes the issue @paultag found running "hy foo" where
foo is not a real file. Also added a test that makes sure
trying to run a non-existent script exits instead of dropping
the user into the REPL.

Added argparse as setup.py resource (and removed from tox.ini) as well as removed uses of deprecated setf
