This change adds a `Version` type to moz.configure which is a small
wrapper around `distutils.version.Version`. It's suitable for wrapping
version numbers in configure checks and doing equality or greater-than
less-than comparisons in a sensible way.

This aligns with the triplets used by clang/llvm. Technically, this
won't break iOS builds still using -darwin triplets until we move
MOZ_IOS_SDK to moz.configure and actively reject non iOS targets with
the iOS sdk.
Also allow to distinguish iOS and OSX with target.os.
Because --enable-application is the current way to do things, transpose
it to configure.py, but since --enable-application=js doesn't make
sense, make it an alias of a new --enable-project option.
This only partially moves --enable-application out of old-configure.in
because there are a lot of other things intertwined with it.
This moves all the reading mozconfig, finding autoconf, refreshing the
old configure, and running the old configure into sandboxed
moz.configure. This effectively bootstraps the sandboxed python configure.
