breaking changes to zig build API and improved caching
* in Zig build scripts, getOutputPath() is no longer a valid function
   to call, unless setOutputDir() was used, or within a custom make()
   function. Instead there is more convenient API to use which takes
   advantage of the caching system. Search this commit diff for
   `exe.run()` for an example.
 * Zig build by default enables caching. All build artifacts will go
   into zig-cache. If you want to access build artifacts in a convenient
   location, it is recommended to add an `install` step. Otherwise
   you can use the `run()` API mentioned above to execute programs
   directly from their location in the cache. Closes #330.
   `addSystemCommand` is available for programs not built with Zig
   build.
 * Please note that Zig does no cache evicting yet. You may have to
   manually delete zig-cache directories periodically to keep disk
   usage down. It's planned for this to be a simple Least Recently
   Used eviction system eventually.
 * `--output`, `--output-lib`, and `--output-h` are removed. Instead,
   use `--output-dir` which defaults to the current working directory.
   Or take advantage of `--cache on`, which will print the main output
   path to stdout, and the other artifacts will be in the same directory
   with predictable file names. `--disable-gen-h` is available when
   one wants to prevent .h file generation.
 * `@cImport` is always independently cached now. Closes #2015.
   It always writes the generated Zig code to disk which makes debug
   info and compile errors better. No more "TODO: remember C source
   location to display here"
 * Fix .d file parsing. (Fixes the MacOS CI failure)
 * Zig no longer creates "temporary files" other than inside a
   zig-cache directory.

This breaks the CLI API that Godbolt uses. The suggested new invocation
can be found in this commit diff, in the changes to `test/cli.zig`.

compile error for import outside package path
closes #2024

there's a new cli option `--main-pkg-path` which you can use to choose
a different root package directory besides the one inferred from the
root source file

and a corresponding build.zig API:
foo.setMainPkgPath(path)

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.

std.io.FileInStream.init(file) -> file.inStream()

Andrew Kelley 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'

Andrew Kelley 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.

Andrew Kelley 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.
