nix dev-shell: Set IN_NIX_SHELL in the derivation
This ensures that stdenv / setup hooks take $IN_NIX_SHELL into
account. For example, stdenv only sets
NIX_SSL_CERT_FILE=/no-cert-file.crt if we're not in a shell.

Matthew Bauer 11d8534629 Use sandbox fallback when cloning fails in builder
When sandbox-fallback = true (the default), the Nix builder will fall
back to disabled sandbox mode when the kernel doesn’t allow users to
set it up. This prevents hard errors from occuring in tricky places,
especially the initial installer. To restore the previous behavior,
users can set:

  sandbox-fallback = false

in their /etc/nix/nix.conf configuration.

Matthew Bauer d171090530 Disable CLONE_NEWUSER when it’s unavailable
Some kernels disable "unpriveleged user namespaces". This is
unfortunate, but we can still use mount namespaces. Anyway, since each
builder has its own nixbld user, we already have most of the benefits
of user namespaces.

nix build: Add '--profile' flag
This replaces 'nix-env --set'. For example:

  $ nix build --profile /nix/var/nix/profiles/system \
      ~/Misc/eelco-configurations:nixosConfigurations.vyr.config.system.build.toplevel

updates the NixOS system profile from a flake.

This could have been a separate command (e.g. 'nix set-profile') but
1) '--profile' is pretty similar to '--out-link'; and 2) '--profile'
could be useful for other command (like 'nix dev-shell').

Niklas Hambüchen a96006d97f Get BOOST_LDFLAGS from autoconf, fix Ubuntu 16.04 build.
Our use of boost::coroutine2 depends on -lboost_context,
which in turn depends on `-lboost_thread`, which in turn depends
on `-lboost_system`.

I suspect that this builds on nix only because of low-level hacks
like NIX_LDFLAGS.

This commit passes the proper linker flags, thus fixing bootstrap
builds on non-nix distributions like Ubuntu 16.04.

With these changes, I can build Nix on Ubuntu 16.04 using:

    ./bootstrap.sh
    ./configure --prefix=$HOME/editline-prefix \
      --disable-doc-gen \
      CXX=g++-7 \
      --with-boost=$HOME/boost-prefix \
      EDITLINE_CFLAGS=-I$HOME/editline-prefix/include \
      EDITLINE_LIBS=-leditline \
      LDFLAGS=-L$HOME/editline-prefix/lib
    make

where

* g++-7 comes from gcc-7 from
  https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test,
* editline 1.14 from https://github.com/troglobit/editline/releases/tag/1.14.0
	was installed into `$HOME/editline-prefix`
  (because Ubuntu 16.04's `editline` is too old to have the function nix uses),
* boost 1.66 from
	https://www.boost.org/doc/libs/1_66_0/more/getting_started/unix-variants.html
	was installed into $HOME/boost-prefix (because Ubuntu 16.04 only has 1.58)

Niklas Hambüchen b49c3a9db5 Makefile.config.in: Remove HAVE_READLINE.
It was forgotten to be removed with
commit c5f23f10a8

in Makefile.config.

Niklas Hambüchen 717e821b99 autoconf: Allow overriding CFLAGS/CXXFLAGS from outside.
As is normal for autoconf-based projects.

For example, it is a common use case to do

    ./configure CXXFLAGS=-O0

This did not work for nix until now, because the `CXXFLAGS=` declaration
would unconditionally erase what the user had specified.

The custom `OPTIMIZE` flag is removed, but the default `-O3` is retained;
autoconf would default to `-g -O2` by default otherwise as documented on:

https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/C-Compiler.html

Niklas Hambüchen 20129bd83d autoconf: Fix AC_STRUCT_DIRENT_D_TYPE being used before AC_PROG_CC.
That was incorrect, because checking the dirent type already requires
a working compiler.

It had the effect that setting e.g. `: ${CFLAGS=""}` before `AC_PROG_CC`
as per `AC_PROG_CC`'s documentation would have no effect, because
`AC_STRUCT_DIRENT_D_TYPE` would automatically set CFLASGS.

(In a followup commit `: ${CFLAGS=""}` will be used, so it's important
to get this working first.)

Sergei Trofimovich fe068eca00 mk: add support for passing LDFLAGS to libs and bins
autotools-based systems usually allow user to
append own LDFLAGS like
    LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu"
at ./configure stage

This change plumbs LDFLAGS through similar to existing CXXFLAGS variable.

Niklas Hambüchen 57daa860e8 autoconf: Fix C++17 detection not working on Ubuntu 16.04.
And probably many other distributions.

Until now, ./configure would fail silently printing a warning

    ./configure: line 4621: AX_CXX_COMPILE_STDCXX_17: command not found

and then continuing, later failing with a C++ #error saying that some C++11
feature isn't supported (it didn't even get to the C++17 features).

This is because older distributions don't come with the
`AX_CXX_COMPILE_STDCXX_17` m4 macro.

This commit vendors that macro accordingly.

Now ./configure complains correctly:

    configure: error: *** A compiler with support for C++17 language features is required.

On Ubuntu 16.04, ./configure completes if a newer compiler is used, e.g. with
gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test
using:

    ./bootstrap.sh
    ./configure CXX=g++-7 --disable-doc-gen --with-boost=$(nix-build --no-link '<nixpkgs>' -A boost.dev)

Niklas Hambüchen 1f97b16b1d autoconf: Work around editline not being found on Ubuntu 16.04.
And probably other Linux distributions with long-term support releases.

Also update manual stating what version is needed;
I checked that 1.14 is the oldest version with which current nix compiles,
and added autoconf feature checks for some functions added in that release
that nix uses.

Niklas Hambüchen 96cd3d6073 autoconf: Change quotes in description.
