dereferencing a *u0 is comptime-known to be 0 2018-09-17 18:13:38 -04:00

remove zig build --init. add zig init-lib and zig init-exe 
init-lib creates a working static library with tests, and
init-exe creates a working hello world with a `run` target.

both now have test coverage with the new "cli tests" file.

fix incorrect error union const value generation 
closes #1442

zig needed to insert explicit padding into this structure before
it got bitcasted.

fix incorrect union const value generation 
closes #1381

The union was generated as a 3 byte struct when it needed to be
4 bytes so that the packed struct bitcast could work correctly.

Now it recognizes this situation and adds padding bytes to become
the correct size so that it can fit into an array.

* error.BadFd is not a valid error code. it would always be a bug to
   get this error code.
 * merge error.Io with existing error.InputOutput
 * merge error.PathNotFound with existing error.FileNotFound.
   Not all OS's support both.
 * add os.File.openReadC
 * add error.BadPathName for windows file operations with invalid
   characters
 * add os.toPosixPath to help stack allocate a null terminating byte
 * add some TODOs for other functions to investigate removing the
   allocator requirement
 * optimize some implementations to use the alternate functions when
   a null byte is already available
 * add a missing error.SkipZigTest
 * os.selfExePath uses a non-allocating API
 * os.selfExeDirPath uses a non-allocating API
 * os.path.real uses a non-allocating API
 * add os.path.realAlloc and os.path.realC
 * convert many windows syscalls to use the W versions (See #534)
