std.io: call the idiomatic std.mem.readInt functions
I originally called the Slice variants to work around
comptime code not supporting `@ptrCast`, but I fixed that
in 757d0665 so now the workaround is no longer needed.

breaking API changes to all readInt/writeInt functions & more
* add `@bswap` builtin function. See #767
 * comptime evaluation facilities are improved to be able to
   handle a `@ptrCast` with a backing array.
 * `@truncate` allows "truncating" a u0 value to any integer
   type, and the result is always comptime known to be `0`.
 * when specifying pointer alignment in a type expression,
   the alignment value of pointers which do not have addresses
   at runtime is ignored, and always has the default/ABI alignment
 * threw in a fix to freebsd/x86_64.zig to update syntax from
   language changes
 * some improvements are pending #863

closes #638
closes #1733

introduce std.io.SeekableStream
Relevant #764

dwarf debug info is modified to use this instead of std.os.File
directly to make it easier for bare metal projects to take advantage
of debug info parsing

Add test for Queue.dump
To make dump testable added dumpToSteam which takes a stream as input
and added the stream as a paraemter to dumpRecursive.

Added test "std.atomic.Queue dump"

And to make the test more robust SliceOutStream.pos is now public. This
allows the user of SliceOutStream to know the length of the data captured.

std.io: PeekStream and SliceStream
SliceStream is a read-only stream wrapper around a slice of bytes. It
allows adapting algorithms which work on InStreams to in-memory data.

PeekStream is a stream wrapper which allows "putting back" bytes into
the stream so that they can be read again. This will help make
look-ahead parsers easier to write.

Pointer Reform: proper slicing and indexing (#1053)
* enable slicing for single-item ptr to arrays
 * disable slicing for other single-item pointers
 * enable indexing for single-item ptr to arrays

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'

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
