The standard library doesn't depend on rustc_bitflags, so move it to explicit
dependencies on all other crates. Additionally, the arena/fmt_macros deps could
be dropped from libsyntax.
Android should use 64-bit LFS symbols for `lseek` and `ftruncate`, lest
those offset parameters suffer a lossy cast down to a 32-bit `off_t`.
Unlike GNU/Linux, Android's `stat`, `dirent`, and related functions are
always 64-bit LFS compatible, and `open` already implies `O_LARGEFILE`,
so all those don't need to follow Linux. It might be nice to unify them
anyway, but those other LFS symbols aren't present in API 18 bionic.

Some struct members have a slighty different name on NetBSD. This has been fixed in the libc crate, but not in libstd, breaking the NetBSD build. Related C struct definition: http://nxr.netbsd.org/xref/src/sys/sys/stat.h?r=1.68#59
This also removes the broken `st_spare()` from MetadataExt, since it is private field reserved for future use.
@dhuseby In case this conflicts with any of your pending patches, feel free to intervene - I'm happy to withdraw this PR.

With these changes you can build a freestanding sysroot without using floating points using a Cargo.toml and copying the `deps` folder cargo outputs.
```
[package]
name = "sysroot"
version = "0.1.0"
[lib]
path = "lib.rs"
crate-type = ["rlib"]
[dependencies.core]
path = "../vendor/rust/src/src/libcore"
features = ["disable_float"]
[dependencies]
collections = { path = "../vendor/rust/src/src/libcollections" }
```

Remove alternate stack with sigaltstack before unmaping it.
Also reuse existing signal stack if already set, this is especially
useful when working with sanitizers that configure alternate stack
themselves.
This change depends on SS_DISABLE recently introduced in libc crate and updates
this git submodule accordingly.
Previously the docs suggested that '❤️' doesn't fit in a char because
it's 6 bytes. But that's misleading. 'a̚' also doesn't fit in a char,
even though it's only 3 bytes. The important thing is the number of code
points, not the number of bytes. Clarify the primitive char docs around
this.
The first time I read the docs for `insert()`, I thought it was saying it didn't update existing *values*, and I was confused. Reword the docs to make it clear that `insert()` does update values.
Because we no longer use `GetFileAttributesExW` FileAttr is never created directly from `WIN32_FILE_ATTRIBUTE_DATA` anymore. So we should no longer store FileAttr's attributes in that c struct.

Is this what you had in mind?
This follows the pattern already used for stat functions from #31551. Now
`ftruncate`, `lseek`, and `readdir_r` use their explicit 64-bit variants for
LFS support, using wider `off_t` and `dirent` types. This also updates to
`open64`, which uses no different types but implies the `O_LARGEFILE` flag.
Non-Linux platforms just map their normal functions to the 64-bit names.
