* Build under bazel sandbox instead of /tmp, and remove redundant printf
Build artifacts under /tmp are not cleaned up after a failed build, for
the ease of debugging. However, this can quickly fill up the /tmp partition
if the build is large. Build under the sandbox directory instead, and
rely on standard bazel cleanup scheme.
Also remove a print from the cleanup function, which somehow causes empty
newlines to be printed in bazel build output.
* Avoid infinite recursion in symlink_to_dir.
This is a somewhat hackish approach to exclude *.ext_build_deps from
symlinks when creating the symlink forest. This is necessary in cases
where an entire directory is added to the includes, e.g. when setting
includes = ["."] where the directory itself contains a cmake_external()
rule that depends on the very rule containing the includes = ["."].
* Also avoid using a temp directory when bootstrapping make or cmake itself.
* Remove the ##tmpdir## shell toolchain command.
It is no longer necessary now that all its uses are gone.

* Allow setting env vars
Also, bring all runfiles of data deps along for execution - currently
data deps which consist of more than one file aren't copied into the
action, which means that they will fail at runtime when they try to use
their runfiles.
* Update docs
