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.

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 :)

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.

The mx_cprng_draw syscall has changed signature to separate the status
and size return values, rather than multiplexing them into a single
value with errors interpreted as a negative value. This patch tracks
that change.

The DirEntryExt::ino() implementation was omitted from the first
iteration of this patch, because a dependency needed to be
configured. The fix is straightforward enough.

It is good practice to implement Debug for public types, and
indicating what directory you're reading seems useful.

Implement `read_offset` and `write_offset`
These functions allow to read from and write to a file from multiple
threads without changing the per-file cursor, avoiding the race between
the seek and the read.

These functions allow to read from and write to a file in one atomic
action from multiple threads, avoiding the race between the seek and the
read.
The functions are named `{read,write}_at` on non-Windows (which don't
change the file cursor), and `seek_{read,write}` on Windows (which
change the file cursor).
