4ae4baac2a Cache command line source for exceptions
Source entered interactively can now be displayed in traceback output.  Also,
the REPL object is now available in its namespace, so that, for instance,
display options--like `spy`--can be turned on and off interactively.

Closes hylang/hy#1397.

fb6feaf082 Improve correspondence with Python errors and console behavior
Compiler and command-line error messages now reflect their Python counterparts.
E.g. where Python emits a `SyntaxError`, so does Hy; same for `TypeError`s.
Multiple tests have been added that check the format and type of raised
exceptions over varying command-line invocations (e.g. interactive and not).

A new exception type for `require` errors was added so that they can be treated
like normal run-time errors and not compiler errors.

The Hy REPL has been further refactored to better match the class-structured
API.  Now, different error types are handled separately and leverage more base
class-provided functionality.

Closes hylang/hy#1486.

cadfa4152b Make colored output configurable
Colored exception output is now disabled by default and configurable through
`hy.errors._hy_colored_errors` and the environment variable
`HY_COLORED_ERRORS`.

Likewise, Hy model/AST color printing is now configurable and disabled by
default.  The corresponding variables are `hy.models._hy_colored_ast_objects`
and `HY_COLORED_AST_OBJECTS`.

Closes hylang/hy#1429, closes hylang/hy#1510.

e468d5f081 Refactor REPL error handling and filter Hy internal trace output
These changes make the Hy REPL more closely follow `code.InteractiveConsole`'s
class interface and provide minimally intrusive traceback print-out filtering
via a context manager that temporarily alters `sys.excepthook`.  In other words,
exception messages from the REPL will no longer show Hy internal
code (e.g. importer, compiler and parsing functions).

The boolean variable `hy.errors._hy_filter_internal_errors` dynamically
enables/disables trace filtering, and the env variable
`HY_FILTER_INTERNAL_ERRORS` can be used as the initial value.

51c7efe6e8 Retain compiled source and file information for exceptions
This commit refactors the exception/error classes and their handling.
It also retains Hy source strings and their originating file information, when
available, all throughout the core parser and compiler functions.

As well, with these changes, calling code is no longer responsible for providing
source and file details to exceptions,

15c68455ec Use a fixed compiler in HyREPL
These changes make `HyREPL` use a single `HyASTCompiler` instance, instead of
creating one every time a valid source string is processed.

This change avoids the unnecessary re-initiation of the standard library
`import` and `require` steps that currently occur within the module tracked by a
`HyREPL` instance.

Also, one can now pass an existing compiler instance to `hy_repl` and
`hy_compiler`.

8b6646d5c9 Remove hy.core compilation requirement from hy package
Previously, when importing `hy` (and any of its sub-packages/modules), Hy source
compilation for `hy.core.language` was necessarily triggered.  This, in turn,
would trigger compilation of the other standard library source files.

This commit removes that chain of events and allows the `hy` package to be
imported without any Hy compilation.

Furthermore, `read` and `read_str` are now implemented in Python and the Hy
standard library files now handle their own dependencies explicitly (i.e. they
`import` and/or `require` the other standard library files upon which they
depend).

The latter changes were necessary, because the automatically triggered
compilation of `hy.core.language` (and associated standard library files) was
serving--implicitly--as a means of producing bytecode in an order that just
happened to work for any compilation occurring afterward.  This chain of
events/dependencies was extremely cryptic, brittle, and difficult to debug, and
these changes should help to remedy that.

Closes hylang/hy#1697.

86fda31ab1 Move compilation and parsing functions out of importer.py
Functions and variables relating to compilation and parsing have been moved to
`compiler.py` and `lex/__init__.py`, respectively.  Those functions are
  - `hy_parse` from `hy.importer` to `hy.lex`
  - `hy_eval`, `ast_compile`, and `calling_module` from `hy.importer` to
  `hy.compiler`

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.
