breaking changes to the way targets work in zig
* CLI: `-target [name]` instead of `--target-*` args.
   This matches clang's API.
 * `builtin.Environ` renamed to `builtin.Abi`
   - likewise `builtin.environ` renamed to `builtin.abi`
 * stop hiding the concept of sub-arch. closes #1526
 * `zig targets` only shows available targets. closes #438
 * include all targets in readme, even those that don't
   print with `zig targets` but note they are Tier 4
 * refactor target.cpp and make the naming conventions
   more consistent
 * introduce the concept of a "default C ABI" for a given
   OS/Arch combo. As a rule of thumb, if the system compiler
   is clang or gcc then the default C ABI is the gnu ABI.

std.debug.assert: remove special case for test builds
Previously, std.debug.assert would `@panic` in test builds,
if the assertion failed. Now, it's always `unreachable`.

This makes release mode test builds more accurately test
the actual code that will be run.

However this requires tests to call `std.testing.expect`
rather than `std.debug.assert` to make sure output is correct.

Here is the explanation of when to use either one, copied from
the assert doc comments:

Inside a test block, it is best to use the `std.testing` module
rather than assert, because assert may not detect a test failure
in ReleaseFast and ReleaseSafe mode. Outside of a test block, assert
is the correct function to use.

fixups, and modify std.mem.join and std.os.path.resolve API
* zig fmt
 * std.mem.join takes a slice of slices instead of var args
 * std.mem.join takes a separator slice rather than byte,
   and always inserts it. Previously it would not insert the separator
   if there already was one, violating the documented behavior.
 * std.mem.join calculates exactly the correct amount to allocate
   and has no call to allocator.shrink()
 * bring back joinWindows and joinPosix and the corresponding tests.
   it is intended to be able to call these functions from any OS.
 * rename std.os.path.resolveSlice to resolve (now resolve takes
   a slice of slices instead of var args)

fcbb7426fa use * for pointer type instead of &
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'

445b03384a introduce std.heap.ArenaAllocator and std.heap.DirectAllocator
* DirectAllocator does the underlying syscall for every allocation.
 * ArenaAllocator takes another allocator as an argument and
   allocates bytes up front, falling back to DirectAllocator with
   increasingly large allocation sizes, to avoid calling it too often.
   Then the entire arena can be freed at once.

The self hosted parser is updated to take advantage of ArenaAllocator
for the AST that it returns. This significantly reduces the complexity
of cleanup code.

docgen and build runner are updated to use the combination of
ArenaAllocator and DirectAllocator instead of IncrementingAllocator,
which is now deprecated in favor of FixedBufferAllocator combined
with DirectAllocator.

The C allocator calls aligned_alloc instead of malloc, in order to
respect the alignment parameter.

Added asserts in Allocator to ensure that implementors of the
interface return slices of the correct size.

Fixed a bug in Allocator when you call realloc to grow the allocation.

a2bd9f8912 std lib: modify allocator idiom
Before we accepted a nullable allocator for some stuff like
opening files. Now we require an allocator.

Use the mem.FixedBufferAllocator pattern if a bound on the amount
to allocate is known.

This also establishes the pattern that usually an allocator is the
first argument to a function (possibly after "self").

fix docs for std.cstr.addNullByte

self hosted compiler:
 * only build docs when explicitly asked to
 * clean up main
 * stub out zig fmt

3671582c15 syntax: functions require return type. remove ->
The purpose of this is:

 * Only one way to do things
 * Changing a function with void return type to return a possible
   error becomes a 1 character change, subtly encouraging
   people to use errors.

See #632

Here are some imperfect sed commands for performing this update:

remove arrow:

```
sed -i 's/\(\bfn\b.*\)-> /\1/g' $(find . -name "*.zig")
```

add void:

```
sed -i 's/\(\bfn\b.*\))\s*{/\1) void {/g' $(find ../ -name "*.zig")
```

Some cleanup may be necessary, but this should do the bulk of the work.

4543413491 std.io: introduce buffered I/O and change API
I started working on #465 and made some corresponding std.io
API changes.

New structs:
 * std.io.FileInStream
 * std.io.FileOutStream
 * std.io.BufferedOutStream
 * std.io.BufferedInStream

Removed:
 * std.io.File.in_stream
 * std.io.File.out_stream

Now instead of &file.out_stream or &file.in_stream to get access to
the stream API for a file, you get it like this:

var file_in_stream = io.FileInStream.init(&file);
const in_stream = &file_in_stream.stream;

var file_out_stream = io.FileOutStream.init(&file);
const out_stream = &file_out_stream.stream;

This is evidence that we might not need any OOP features -
See #130.
