introduce std.fs.Dir.openFile and std.fs.Dir.createFile
These functions have flags parameters which cover all the use cases. The
other functions are now deprecated.

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.

51c5740879 Use a specific access mask in Dir.openDirListW instead of a generic one. Untested.
The actual desired access mask in this case seems quite confusing and badly documented. The previous combination of `GENERIC_READ` and `SYNCHRONIZE` seems both illegal and redundant according to the [`ntifs.h` documentation](https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntcreatefile), which specifies that `GENERIC_READ` should not be used for directories and includes `SYNCHRONIZE`. `winnt.h` contains a number of relevant-sounding flags such as `FILE_ADD_FILE`, `FILE_ADD_SUBDIRECTORY`, and `FILE_DELETE_CHILD` that do not show up in documentation at all. These are equal in value to file-specific flags that are documented as flags you should not specify when opening a directory.

17bc1f62a5 Split std.fs.Dir.openDir into openDirList and openDirTraverse to clarify what directories can be iterated. Closes ziglang/zig#3741.
The Windows-inspired nomenclature of "List" and "Traverse" was chosen over POSIX-style "Read" and "Path" (from `O_PATH`) for clarity. Using "Path" makes it look like the function is manipulating strings, and the generic "Read" ending isn't useful when there is no generic read method. Even in implementation details, `read` is never used.

Actual exploitation of the difference between the two functions will come in a later commit.

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.

get rid of std.os.foo.is_the_target
It had the downside of running all the comptime blocks and resolving
all the usingnamespaces of each system, when just trying to discover if
the current system is a particular one.

For Darwin, where it's nice to use `std.Target.current.isDarwin()`, this
demonstrates the utility that #425 would provide.

breaking: improve std.fs directory handling API
* Added `std.c.unlinkat` and `std.os.unlinkat`.
 * Removed `std.fs.MAX_BUF_BYTES` (this declaration never made it to
   master branch)
 * Added `std.fs.Dir.deleteTree` to be used on an open directory handle.
 * `std.fs.deleteTree` has better behavior for both relative and
   absolute paths. For absolute paths, it opens the base directory
   and uses that handle for subsequent operations. For relative paths,
   it does a similar strategy, using the cwd handle.
 * The error set of `std.fs.deleteTree` is improved to no longer have
   these possible errors:
   - OutOfMemory
   - FileTooBig
   - IsDir
   - DirNotEmpty
   - PathAlreadyExists
   - NoSpaceLeft
 * Added `std.fs.Dir.posix_cwd` which is a statically initialized
   directory representing the current working directory.
 * The error set of `std.Dir.open` is improved to no longer have these
   possible errors:
   - FileTooBig
   - IsDir
   - NoSpaceLeft
   - PathAlreadyExists
   - OutOfMemory
 * Added more alternative functions to `std.fs` for when the path
   parameter is a null terminated string. This can sometimes be more
   effecient on systems which have an ABI based on  null terminated
   strings.
 * Added `std.fs.Dir.openDir`, `std.fs.Dir.deleteFile`, and
   `std.fs.Dir.deleteDir` which all operate on an open directory handle.
 * `std.fs.Walker.Entry` now has a `dir` field, which can be used to do
   operations directly on `std.fs.Walker.Entry.basename`, avoiding
   `error.NameTooLong` for deeply nested paths.
 * Added more docs to `std.os.OpenError`

This commit does the POSIX components for these changes. I plan to
follow up shortly with a commit for Windows.

[breaking] standardize std.os execve functions
* `std.os.execve` had the wrong name; it should have been
   `std.os.execvpe`. This is now corrected.
 * introduce `std.os.execveC` which does not look at PATH, and uses
   null terminated parameters, matching POSIX ABIs. It does not
   require an allocator.
 * fix typo nonsense doc comment in `std.fs.MAX_PATH_BYTES`.
 * introduce `std.os.execvpeC`, which is like `execvpe` except it
   uses null terminated parameters, matching POSIX ABIs, and thus
   does not require an allocator.
 * `std.os.execvpe` implementation is reworked to only convert
   parameters and then delegate to `std.os.execvpeC`.
 * `std.os.execvpeC` improved to handle `ENOTDIR`. See #3415
