When WSASocketW gets WSANOTINITIALISED, now it will lock a mutex to
safely call WSAStartup and then try again one time.
This implementation:
* Does not use recursion
* Contains a detailed doc comment explaining why things are how they are
* Is careful about which errors are surfaced in the respective error
sets. `std.os.socket` intentionally does not have "not initialised"
as one of the possible errors.
The atfork handler is executed even when fork()-ing threads that have
never initialized their local csprng. Handle this case gracefully
instead of raising a runtime error.
Fixes#8841
Some libc implementations (glib) deduplicate identical hooks, others
(musl, macos) do not and blindly append them to an internal list.
Ensure there's only a single call to pthread_atfork to prevent unbounded
memory use when lots of threads/forks are used.
Now that `@import` of a non-existent file name is a compile error, the
Zig installation needs to include files that end with test.zig. However
we still want to avoid bloat in the installation size, so we blank them
out instead of omitting them entirely.
Now AstGen of the full standard library can complete successfully on a
Zig installation rather than erroring out with file not found.
A previous commit from this branch incorrectly changed the usage of
`comptime` keyword, and broke the std lib tests. This commit adds
`comptime` to a few function calls, correcting the behavior.

We're going to want to improve the stage2 test harness to print
the source file name when a compile error occurs otherwise std lib
contributors are going to see some confusing CI failures when they cause
stage2 AstGen compile errors.
Let mmap allocate a block of memory that's wide enough to use with
MADV_WIPEONFORK, madvise granularity is the current system page size
(using a static buffer of mem.page_size bytes would be wrong, that's the
minimum page size).
As a result, we don't zero some random chunk of memory every time we
fork the process.

- this one might be problematic; start.zig looks for `main` in the
root source file, not `_main`. Not sure why there is an underscore
there in master branch.
Use .bold instead of .white, the effect is the same for light-on-dark
terminals but greatly improves the readability for dark-on-light ones.
Closes#8761
* std: fix overflow in math.scalbn32
* std: rewrite math.scalbn to be generic
* std: support f128 in math.isNormal
* std: enable f128 tests in math.scalbn
we only effectively need 1 control bit to represent 2 special states for
the metadata (free and tombstone)
this should reduce the number of actual element equality tests, but since
it's very low already, the impact is negligible
The `1 - shift` expression was computed using small unsigned types and
then casted to i32, producing either an underflow error or an incorrect
result.
Reported by `@notviri` in #8733
* for cross testing stage2 tests, we use `darling shell` command
since the path to the tested binary is relative to cwd
* for the `zig test` command, we simply use `darling` since the
path to the binary is absolute
Without this, and with `-Denable-qemu -Denable-foreign-glibc`,
i386-linux-gnu tests failed because the `-L` path passed to qemu
was "i386-linux-gnu" (nonexistent) rather than "i686-linux-gnu".
Fixes std lib and behavior tests when using these options to enable
test coverage with cross compiled glibcs.

Mainly I wanted Jakub's new macOS code for respecting stack size, since
we now depend on it for debug builds able to pass one of the test cases
for recursive comptime function calls with `@setEvalBranchQuota`.
The conflicts were all trivial.
