Picking up build2 and updating the Changelog

There is no `extension-overrides.js` in a profile direcory anymore.

For some reason the switch from 60.0.1esr to 60.1.0esr is causing
to break our builds because the 32bit linker is not capable of linking
gkrust nor libxul due to address space limitations anymore.

We keep the configuration for 32bit Linux bundles as we shipped them in
our nightly builds over the past couple of weeks but are avoiding
building browser debug information for now.

Use make_path instead of mkdir to create all needed parent directories.

`intl.locale.matchOS` has been deprecated and the new preference is
`intl.locale.requested`, which is set by commit 473342ee. See bug
26073 for more information.

Changelog update and versions bump

Richard Pospesel authored Jun 19, 2018 and Georg Koppen committed Jun 22, 2018

The infrastructure for loading extension-overrides.js no longer
exists in ESR60, so these prefs had to be moved.

Unfortunately, we can't just dump the contents of extension-overrides.js
into 000-tor-browser.js.  The settings are actually partially built in
tor-browser-build to conditionally include various bridge strings as well
as localization settings.  So, we piggy back off this existing build
process and just append the contents of the partially generated
extension-overrids.js to 000-tor-browser.js.

Starting with content sandboxing being enabled our seatbelt profiles
have been broken (see: #22000). We should remove them for now to avoid
a broken experience in the alphas.

This commit adds support for building the 64-bit version of NSIS, and
also bumps the version to 3.03. Doing this enables us to build MAR files
in a 64-bit container for the 64-bit version of Tor Browser; see bug
26363 and bug 24477.

The pe_checksum_fix.py doesn't work in a 64-bit container with the
bundled python-pefile version so we build its latest version to fix this
issue. This change is borrowed from commit bb32ec91 and updates
python-pefile to 2017.11.5.

The Debian package and the patches are no longer required as all changes
were merged upstream in 3.01-1. (See the nsis changelog in Debian.)

Mozilla switched from Bzip2 to LZMA as compression algorithm for MAR
files during th Firefox 56. That means esr52-based Tor Browsers don't
understand LZMA yet. Thus, we still use Bzip2 for the first esr60-based
MAR files and switch afterwards to LZMA.

sandboxed-tor-browser is not maintained anymore and Yawning requested to
not ship it anymore in our alphas once we switch to Firefox 60 ESR.

Bumping Rust to 1.26.1 avoids intermittent Firefox compilation failures
we have seen, similar to those Mozilla got and documented in
https://bugzilla.mozilla.org/show_bug.cgi?id=1445413.

The fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1443823 makes
our workaround for https://bugzilla.mozilla.org/show_bug.cgi?id=1392604
obsolete, and we can remove it as it landed on esr60.

Also enable rust for all builds.

This commit adds support for building and bundling fxc2 which is
required for Windows cross-compilation on Linux.

We were setting the minSupportedInstructionSet attribute for the win32
updates only. We now set it on all platforms.

Add the htaccess_rewrite_rules option which can be used to specify
rewrite rules to be added to the generated .htaccess files.

The 32bit toolchain is not able to link libxul anymore with selfrando
enabled as the linker is running out of address space. We therefore
disable selfrando for 32bit for now.
