This gets rid of the last use of the 'which' module left in the tree. So not
only will this help 'configure' become a little more Python 3 compatible, but
we can now remove 'third_party/python/which'.

The configure sandbox has wrapped subprocess methods to add its own
encoded environment if none is provided, since bug 1520394. It only
makes sense that it normalizes the environment that comes in too,
avoiding caller in the configure sandbox to have to do it themselves.
OTOH, and while we're here, none of get_cmd_output, old_configure or the
sandbox were actually using the right encoding for this conversion, so
fix the configure sandbox to use the right one, and make it stop using
encode(), which does deep recursion that is not necessary here, and that
I'm trying to remove entirely.
Also while here, remove an unused import of encode().

Because most calling places in python configure don't actually want to
deal with encodings, although in practical terms they should, make
get_cmd_output handle it itself.
Places that explicitly do want bytes can keep using subprocess directly.

Bug 1520394 changed things such that the configure sandbox is using a
copy of os.environ. So when mozconfig injects environment changes, they
only affect the sandbox. Which means when the which module uses
os.environ to get PATH, it gets the original unmodified environment.
So instead of relying on the which module getting PATH itself, we feed
it with it. It's worth noting that the which module adds `.` on Windows,
but we don't copy this behavior, because in the context of configure,
it's actually not important (`.` would be the topobjdir).

Running rustc with an open fd 4 sometimes causes it to fail with an obscure
error when it tries to connect to a job server on that fd. Closing the fd
solves the problem.
close_fds does what we need, and is the default value in Python 3, but not
in Python 2.

Bug 1282866 removed the only configuration where it did something.
Since then, using it only leads to a configure error.

Currently, --enable-lto just implies --enable-linker=lld, which
essentially only works on Linux, and assumes one can't do lto with
anything other than lld. Which is not true. As a matter of fact, even
ld.bfd can do lto, as long as the gold plugin for llvm is available,
or when doing lto with GCC instead of clang.
Anyways, to allow more lto setups, we adapt the --enable-linker setup
to:
- work on macOS, which it currently doesn't, and add support for the mac
linker (ld64), which, unfortunately, doesn't have a clean way to be
detected, so work around that.
- default to lld if lto is enable, no linker was explicitly given, the
compiler is clang *and* the build target is not macOS.

LineIO currently attempts to convert bytes to unicode using the
system preferred encoding. This can obviously fail for some byte
sequences.
In many cases, the conversion is happening for purposes of logging.
In these cases, Unicode validation shouldn't be that important to
us.
So, this commit teaches LineIO to accept an argument defining its
Unicode error mode. We also teach relevant users of LineIO doing
logging to switch the default mode from "strict" to "replace" so
invalid Unicode byte sequences can be logged with the Unicode
replacement character.
During review, glandium pointed out that it may make better sense
to defer Unicode decoding to the logging layer instead of in LineIO.
I agree with this idea. But it can be implemented in another bug:
for now we should unbust the build system.

Often you only want to evaluate a function if all its dependencies
are true. Expressing this in a "when" can be difficult. So let's
add a convenience decorator for it.
The existing code for @depends_if() was refactored to take an
evaluation function as its first argument. This prevents some
duplicate code and turns @depends_if() and @depends_all() into
one-liners.

The values that we need to find in the registry can be inconsistent across
different installations, so we retrieve values from both views in our search
for a valid SDK. This also ensures this works for 32-bit and 64-bit python.
And include code to work around a bug on older Python versions.
