* re-introduce `std.build.Target` which is distinct from `std.Target`.
`std.build.Target` wraps `std.Target` so that it can be annotated as
"the native target" or an explicitly specified target.
* `std.Target.Os` is moved to `std.Target.Os.Tag`. The former is now a
struct which has the tag as well as version range information.
* `std.elf` gains some more ELF header constants.
* `std.Target.parse` gains the ability to parse operating system
version ranges as well as glibc version.
* Added `std.Target.isGnuLibC()`.
* self-hosted dynamic linker detection and glibc version detection.
This also adds the improved logic using `/usr/bin/env` rather than
invoking the system C compiler to find the dynamic linker when zig
is statically linked. Related: #2084
Note: this `/usr/bin/env` code is work-in-progress.
* `-target-glibc` CLI option is removed in favor of the new `-target`
syntax. Example: `-target x86_64-linux-gnu.2.27`
closes#1907
1. behavior tests with --test-evented-io
2. std lib tests with --test-evented-io
3. fuzz test evented I/O a bit, make it robust
4. make sure it works on all platforms (kqueue, Windows IOCP,
epoll/other)
5. restart efforts on self-hosted
* 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)
* introduce std.atomic.Int
* add src-self-hosted/test.zig which is tested by the main test suite
- it fully utilizes the multithreaded async/await event loop so the
tests should Go Fast
* `stage2/bin/zig build-obj test.zig` is able to spit out an error if 2 exported
functions collide
* ability for `zig test` to accept `--object` and `--assembly`
arguments
* std.build: TestStep supports addLibPath and addObjectFile

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'
Commands are now separated more precisely from one another. Arguments
are parsed mostly using a custom argument parser instead of manually.
This should be on parity feature-wise with the previous main.zig but
adds a few extra code-paths as well that were not yet implemented.
Subcommands are much more prominent and consistent. The first argument
is always a sub-command and then all following arguments refer to that
command. Different commands display there own usage messages and options
based on what they can do instead of a one-for-all usage message that
was only applicable for the build commands previously.
The `cc` command is added and is intended for driving a c compiler. See #490.
This is currently a wrapper over the system cc and assumes that it
exists, but it should suffice as a starting point.
