* respect max_output_bytes
* std.ArrayList:
- make `allocatedSlice` public.
- add `unusedCapacitySlice`.
I removed the Windows implementation of this stuff; I am doing a partial
merge of LemonBoy's patch with the understanding that a later patch can
add the Windows implementation after it is vetted.
We were violating the POSIX standard which resulted in a deadlock on
musl v1.1.24 on aarch64 alpine linux, uncovered with the new ThreadPool
usage in the stage2 compiler.
std.os execv functions that accept an Allocator parameter are removed
because they are footguns. The POSIX standard does not allow calls to
malloc() between fork() and execv() and since it is common to both
(1) call execv() after fork() and (2) use std.heap.c_allocator,
Programmers are encouraged to go through the `std.process` API
instead, causing some dissonance when combined with `std.os` APIs.
I also slapped a big warning message on all the relevant doc comments.
Everybody gets what they want!
* AT_RANDOM is completely ignored.
* On Linux, MADV_WIPEONFORK is used to provide fork safety.
* On pthread systems, `pthread_atfork` is used to provide fork safety.
* For systems that do not have the capability to provide fork safety,
the implementation falls back to calling getrandom() every time.
* If madvise is unavailable or returns an error, or pthread_atfork
fails for whatever reason, it falls back to calling getrandom() every
time.
* Applications may choose to opt-out of fork safety.
* Applications may choose to opt-in to unconditionally calling
getrandom() for every call to std.crypto.random.fillFn.
* Added `std.meta.globalOption`.
* Added `std.os.madvise` and related bits.
* Bumped up the size of the main thread TLS buffer. See the comment
there for justification.
* Simpler hot path in TLS initialization.
Find the effective ELF load address in dl_iterate_phdr by computing the
difference between the in-memory phdr and its p_vaddr specified in the
ELF file.
This makes the dl_iterate_phdr test pass and restores the stack traces.
* add more abosolutes
* added wrong files
* adding 2 tests and changing the function signatures because of lazy analysis not checking them
* fix a bug that got uncovered by lazy eval
* Add compile error when using WASI with openDirAbsolute and accessAbsolute
* typo
There's no guarantee for the kernel definition to be ABI compatible with
the libc one (and vice versa).
There's also no guarantee of ABI compatibility between musl/glibc.
Fun, isn't it?

This commit resolves conflicts with the changes to std.os which removed
the EAGAIN error handling interactions with the event loop. The solution
to the conflict was to apply EAGAIN => return error.WouldBlock into the
improved windows networking branch.
