Fix current_exe() on DragonFly (again)
This is a follow up on [this pull request][1].
Since DragonFly 4.6.1 ([this commit][2]), the ```kern.proc.pathname```
sysctl works correctly, i.e. it does not return paths including a ```:```
(see [here][3]). Use it and don't try to fix old versions of DragonFly!
There are not many DragonFly installations out there that we can't
control and no one is compiling Rust from source. If someone wants to
run Rust on a pre-4.6.1 DragonFly system, the ports system should
provide a patch.

fix objc ABI in std::env::args
iOS use different calling convention for `objc_msgSend` depending on the platform. armv7 expect good old variadic arguments, but aarch64 wants "normal" convention: `objc_msgSend` has to be called mimicking the actual callee prototype.
https://developer.apple.com/library/content/documentation/General/Conceptual/CocoaTouch64BitGuide/ConvertingYourAppto64-Bit/ConvertingYourAppto64-Bit.html#//apple_ref/doc/uid/TP40013501-CH3-SW26
This currently breaks std::env:args() on aarch64 iOS devices. As far as I can tell, in the standard library, this is the only occurrence of ObjectiveC dispatching.

Add std::os::windows::process::CommandExt. Fixes #37827
This adds a CommandExt trait for Windows along with an implementation of it
for std::process::Command with methods to set the process creation flags that
are passed to CreateProcess.

Fuchsia support for std::process via liblaunchpad.
Now we can launch processes on Fuchsia via the Rust standard library! ... Mostly.
Right now, ~5% of the time, reading the stdout/stderr off the pipes will fail. Some Magenta kernel people think it's probably a bug in Magenta's pipes. I wrote a unit test that demonstrates the issue in C, which I was told will expedite a fix. https://fuchsia-review.googlesource.com/#/c/15628/
Hopefully this can get merged once the issue is fixed :)

refactored out some now-duplicated code into a 'process_common.rs'

On unix like systems, the underlying file corresponding to any given path may
change at any time. This function makes it possible to set the permissions of
the a file corresponding to a `File` object even if its path changes.

libstd: support creation of anonymous pipe on WinXP/2K3
`PIPE_REJECT_REMOTE_CLIENTS` flag is not supported on Windows < VISTA, and every invocation of `anon_pipe` including attempts to pipe `std::process::Child`'s stdio fails.
This PR should work around this issue by performing a runtime check of windows version and conditionally omitting this flag on "XP and friends".
Getting the version should be probably moved out of the function `anon_pipe` itself (the OS version does not often change during runtime :) ), but:
- I didn't find any precedent for this and assuming there's not much overhead (I hope windows does not perform any heuristics to find out it's own version, just fills couple of fields in the struct).
- the code path is not especially performance sensitive anyway.
