* get rid of the pointless fences
* make seed_len 16 instead of 32, which is accurate since it was
already padding the rest anyway; now we do 1 pad instead of 2.
* secureZero to clear the AT_RANDOM auxval
* add a flag root source files can use to disable the start code. This
is in case people want to opt out of the initialization when they
don't depend on it.
std.crypto.random
* cross platform, even freestanding
* can't fail. on initialization for some systems requires calling
os.getrandom(), in which case there are rare but theoretically
possible errors. The code panics in these cases, however the
application may choose to override the default seed function and then
handle the failure another way.
* thread-safe
* supports the full Random interface
* cryptographically secure
* no syscall required to initialize on Linux (AT_RANDOM)
* calls arc4random on systems that support it
`std.crypto.randomBytes` is removed in favor of `std.crypto.random.bytes`.
I moved some of the Random implementations into their own files in the
interest of organization.
stage2 no longer requires passing a RNG; instead it uses this API.
Closes#6704
ad05509 introduced a fix for the wrong problem, the logic to align the
start of main_thread_tls_buffer was already there but was flawed.
Fix it for good and avoid wasting too many bytes for alignment purposes.
auto_hash must be extra careful when hashing integers whose bit size is
not a multiple of 8 as, when reinterpreted with mem.asBytes, may contain
undefined non-zero bits too.
- addrinfo: addr and canonname are switched (wrong layout)
- addrinfo, Flock, msghdr struct: use proper c_xxx type instead of fixed size. it should help using struct on all architectures supported by openbsd
Xnu's sigaction() only supports fetching a limited set of sa_flags, test
SA_SIGINFO instead of SA_RESETHAND as that's supported everywhere.
Add another check to make sure SA_RESETHAND works.

extension("a.") now returns "." instead of "".
This matches both Python and Node.js standard library behavior as well
as my personal opinion on how this function should be defined.
Apologies for missing this in the code review.
* Field global_cache_root was added to Builder struct along with
mandatory argument for build_runner.zig. Logic for using the custom
global cache was also added.
* The arguments --cache-dir and --global-cache-dir are no longer passed
directly through to build_runner.zig and are instead only passed through the
mandatory cache_root and global_cache_root arguments.
