self-hosted libc detection
* libc_installation.cpp is deleted.
   src-self-hosted/libc_installation.zig is now used for both stage1 and
   stage2 compilers.
 * (breaking) move `std.fs.File.access` to `std.fs.Dir.access`. The API
   now encourages use with an open directory handle.
 * Add `std.os.faccessat` and related functions.
 * Deprecate the "C" suffix naming convention for null-terminated
   parameters. "C" should be used when it is related to libc. However
   null-terminated parameters often have to do with the native system
   ABI rather than libc. "Z" suffix is the new convention. For example,
   `std.os.openC` is deprecated in favor of `std.os.openZ`.
 * Add `std.mem.dupeZ` for using an allocator to copy memory and add a
   null terminator.
 * Remove dead struct field `std.ChildProcess.llnode`.
 * Introduce `std.event.Batch`. This API allows expressing concurrency
   without forcing code to be async. It requires no Allocator and does
   not introduce any failure conditions. However it is not thread-safe.
 * There is now an ongoing experiment to transition away from
   `std.event.Group` in favor of `std.event.Batch`.
 * `std.os.execvpeC` calls `getenvZ` rather than `getenv`. This is
   slightly more efficient on most systems, and works around a
   limitation of `getenv` lack of integration with libc.
 * (breaking) `std.os.AccessError` gains `FileBusy`, `SymLinkLoop`, and
   `ReadOnlyFileSystem`. Previously these error codes were all reported
   as `PermissionDenied`.
 * Add `std.Target.isDragonFlyBSD`.
 * stage2: access to the windows_sdk functions is done with a manually
   maintained .zig binding file instead of `@cImport`.
 * Update src-self-hosted/libc_installation.zig with all the
   improvements that stage1 has seen to src/libc_installation.cpp until
   now. In addition, it now takes advantage of Batch so that evented I/O
   mode takes advantage of concurrency, but it still works in blocking
   I/O mode, which is how it is used in stage1.

fix off-by-one error in std.unicode.utf8ToUtf16LeWithNull
and fix larger-than-one-byte sentinels when being freed

Thank you to João Pedro for identifying both problems and
providing example code to solve them.

0deab8fd3b Add std.mem.zeroes to the standard library
This zero initializes the type passed in. Can be used to zero
initialize c structs.

std.mem.compare: breaking API changes

   renamed to follow new style convention.
 * `std.mem.compare` is renamed to `std.mem.order`.
 * new function `std.math.order`

sentinel slicing improvements
* add runtime safety for slicing pointers, arrays, and slices.
 * slicing without a sentinel value results in non-sentineled slice
 * improved `std.debug.panic` handling of panic-during-panic

Replace @typeOf with @TypeOf in all zig source
This change was mostly made with `zig fmt` and this also modified some whitespace. Note that in some files, `zig fmt` produced incorrect code, so the change was made manually.

remove type coercion from array values to references
* Implements #3768. This is a sweeping breaking change that requires
   many (trivial) edits to Zig source code. Array values no longer
   coerced to slices; however one may use `&` to obtain a reference to
   an array value, which may then be coerced to a slice.

 * Adds `IrInstruction::dump`, for debugging purposes. It's useful to
   call to inspect the instruction when debugging Zig IR.

 * Fixes bugs with result location semantics. See the new behavior test
   cases, and compile error test cases.

 * Fixes bugs with `@typeInfo` not properly resolving const values.

 * Behavior tests are passing but std lib tests are not yet. There
   is more work to do before merging this branch.

string literals are now null terminated
this also deletes C string literals from the language, and then makes
the std lib changes and compiler changes necessary to get the behavior
tests and std lib tests passing again.

make std.net more portable
* Delete `std.net.TmpWinAddr`. I don't think that was ever meant to
   be a real thing.
 * Delete `std.net.OsAddress`. This abstraction was not helpful.
 * Rename `std.net.Address` to `std.net.IpAddress`. It is now an extern
   union of IPv4 and IPv6 addresses.
 * Move `std.net.parseIp4` and `std.net.parseIp6` to the
   `std.net.IpAddress` namespace. They now return `IpAddress` instead of
   `u32` and `std.net.Ip6Addr`, which is deleted.
 * Add `std.net.IpAddress.parse` which accepts a port and parses either
   an IPv4 or IPv6 address.
 * Add `std.net.IpAddress.parseExpectingFamily` which additionally
   accepts a `family` parameter.
 * `std.net.IpAddress.initIp4` and `std.net.IpAddress.initIp6` are
   improved to directly take the address fields instead of a weird
   in-between type.
 * `std.net.IpAddress.port` is renamed to `std.net.IpAddress.getPort`.
 * Added `std.net.IpAddress.setPort`.
 * `os.sockaddr` struct on all targets is improved to match the
   corresponding system struct. Previously I had made it a union of
   sockaddr_in, sockaddr_in6, and sockaddr_un. The new abstraction for
   this is now `std.net.IpAddress`.
 * `os.sockaddr` and related bits are added for Windows.
 * `os.sockaddr` and related bits now have the `zero` fields default
   to zero initialization, and `len` fields default to the correct size.
   This is enough to abstract the differences across targets, and so
   no more switch on the target OS is needed in `std.net.IpAddress`.
 * Add the missing `os.sockaddr_un` on FreeBSD and NetBSD.
 * `std.net.IpAddress.initPosix` now takes a pointer to `os.sockaddr`.
