Fix shell function symlink_contents_to_dir, add test
- test for the case when we symlink the contents of two directories with the same inner directories (include)
- the test data of the test for shell script helper also changes, as it uses the real shell toolchain implementation text
- Fixes the issue from #330
Fix shell_script_helper.bzl to replace function calls inside function texts.
Add test for shell_script_helper.bzl.
In particular, this fixes the case when some of the shell toolchain functions calls other shell toolchain functions (symlink_contents_to_dir and symlink_to_dir).
Allow to specify working directory for cmake_external
For LLVM case, when main CMakeLists.txt is in the /llvm subdirectory in the source tree

Rules_foreign_cc also currently is not using CcInfo.quote_includes.
Having them leads to symlinking directory trees without any reason.
Tests: we already have tests for transitive Bazel dependencies (//cmake_synthetic:test_bazel_transitive_deps, //cmake_with_bazel_transitive:test, //configure_with_bazel_transitive:test)
* Fix permission problem with replacing absolute path with sed, #306
- we can not modify files under Bazel's output directory
- so we can not modify pkg_config files, written there, for instance
- solution: only replace absolute paths in the files being created by the current target,
using the environment variable as the replacement value ($EXT_BUILD_DEPS)
* Wrap environment variable in ${} in replace string
Apparently, it is not the problem for build outputs, but deps directory that is created by script.
What is even more problematic is that this directory can be accessed while building this target in parallel for different configurations. So even if we clean it before using, we might break the build of the parallel target.
Solution: create temp directory to be used as deps directory.
(Additionally, this demonstrates the benefits of sandboxed execution.)
Be resilient with Bazel-built transitive dependencies duplicates
- it is possible that some duplicate libraries, built with Bazel, will be passed as inputs to cmake_external or configure_make. rules_foreign_cc should filter duplicates out rather then fail.
- add a test (which just builds the target) //cmake_synthetic:lib_with_duplicate_transitive_bazel_deps
Adapt rules_foreign_cc for working with libtool instead of ar.
- for CMake, pass "<TARGET>" as the output file when forming linker flags with cc_common. CMake will later replace <TARGET> with the actual output file. Fill CMAKE_C_CREATE_ARCHIVE and CMAKE_CXX_CREATE_ARCHIVE CMake variables with 'CMAKE_AR %Bazel-link-flags% <OBJECTS>' call, where CMAKE_AR will take the path to libtool.

- for configure_make, for the libevent example, we need to skip specifying the libtool from Bazel's toolchain as a linker, because libevent script uses it's own libtool and manages to pass the output file to it, but not to the libtool we are passing. Let it do so as it is a customized script.
Do it with specifying empty string for the $AR environment variable.
Other examples with configure_make work fine.
This fixes https://github.com/bazelbuild/bazel/issues/9258
* Build Android example on CI
Currently there aren't any actual test targets for the NDK example, but
building it is still useful to verify.
* Remove from windows
* Fix a way of wiping CMake cache entry values defined by toolchain from a command line, in case user specified empty values for these cache entries explicitly in cmake_external target
- it was a problem that we did not check that there was some value in the "toolchain" dict before we pop() - reported in comment in #292
- make code which does wiping empty values more explicit
* Additionally, if non-empty value for CMAKE_RANLIB was not specified by user or Bazel toolchain, put empty value for it to forbid CMake to auto detect it
context: https://github.com/bazelbuild/rules_foreign_cc/issues/252
* Add test for user's redefined value for CMAKE_BUILD_TYPE
* Implement support for "pure" GNU Make in make.bzl
Usage: load("@rules_foreign_cc//tools/build_defs:make.bzl", "make")
make(name = <name>, lib_source = <source>), please see more arguments
in make.bzl
Add test in examples/simple_make (runs only on Linux because of Makefile contents)
* examples: cmake_crosstool: Remove executable bit from BUILD
There is no reason for BUILD file to be an executable.

* examples: Add shebang to the bash script
print_bazel_version.sh is a bash script, but it did not contain a
shebang.

* Fix replace_in_files function in windows_commands.bzl
Filter files by types, where the absolute paths need to be replaced.
* Add one more hello world example
* Include test into windows list, remove from Mac OS list
* fix(cmake): Use "Debug" and "Release" instead of "DEBUG" and "RELEASE"
These values are case-sensitive in cmake and give this error currently:
```
CMake Error at CMakeLists.txt:23 (message):
CMAKE_BUILD_TYPE must be one of: Debug, Release (current value: 'RELEASE')
```
* update test data
The line number doesn't match the exact location of the position of the content. This is tolerable with patch command line tool, but it won't work with a more strict patch implementation.
Context: https://github.com/bazelbuild/bazel/pulls
Fix the code to work with Bazel HEAD:
- convert depset to list for iteration (libraries to link)
- _build_tools() are just creating the file, not contributing anything to the text of constructed BUILD file, so make a call to this method separately.
This PR adds @bazel_version repository which contains single def.bzl
file which contains a BAZEL_VERSION constant that can be used to perform
conditional logic bazed on the Bazel version.
As a result, rules_foreing_cc are now compatible with Bazel 0.24 - 0.27
(at least regarding configure_features :)
For cmake_external and configure_make, do not prepend relative install prefix path with "./", as it is recognized as relative and gets appended to the current build directory anyway, forming the path /tmp/something/./install_prefix - which does not make much sense.
