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 a35b366eb6 [breaking] delete ptr deref prefix op
start using zig-fmt-pointer-reform branch build of zig fmt
to fix code to use the new syntax

all of test/cases/* are processed, but there are more left
to be done - all the std lib used by the behavior tests

Andrew Kelley caefaf781e std.debug: dumpStackTrace & friends use DirectAllocator
this has the downside of failing to print a stack trace
when the system is out of memory (maybe we could add a
FallbackAllocator which tries DirectAllocator and falls
back on the 200KB preallocated buffer).

but for the more common use case when the system is not
out of memory, but the debug info cannot fit in
std.debug.global_allocator, now stack traces will work.

this is the case for the self hosted compiler.

Andrew Kelley 60b2031831 improvements to stack traces
* @panic generates an error return trace
 * printing an error return trace no longer interferes with
   normal stack traces.
 * instead of ignore_frame_count, we look at the return address
   when you call panic, and that's the first stack trace function
   makes stack traces much cleaner - the error return trace
   flows gracefully into the stack trace

Ben Noordhuis ab48934e9c add support for stack traces on macosx
Add basic address->symbol resolution support.  Uses symtab data from the
MachO image, not external dSYM data; that's left as a future exercise.

The net effect is that we can now map addresses to function names but
not much more.  File names and line number data will have to wait until
a future pull request.

Partially fixes #434.

Andrew Kelley 4a4ea92cf3 remove std.heap.IncrementingAllocator
Use std.heap.FixedBufferAllocator combined with
std.heap.DirectAllocator instead.

Andrew Kelley 46aa416c48 std.os and std.io API update
* move std.io.File to std.os.File
 * add `zig fmt` to self hosted compiler
 * introduce std.io.BufferedAtomicFile API
 * introduce std.os.AtomicFile API
 * add `std.os.default_file_mode`
 * change FileMode on posix from being a usize to a u32
 * add std.os.File.mode to return mode of an open file
 * std.os.copyFile copies the mode from the source file instead of
   using the default file mode for the dest file
 * move `std.os.line_sep` to `std.cstr.line_sep`

Andrew Kelley 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

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.

Andrew Kelley 2a25398c86 fix segfault when passing union enum with sub byte...
...field to const slice parameter

we use a packed struct internally to represent a const array
of disparate union values, and needed to update the internal
getelementptr instruction to recognize that.
