* 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.
Fix #232 - enable usage of Bazel-built libraries as dependencies of cmake_external and configure_make.
- fix logic of reading library data described by C/C++ Bazel interface (as CcInfo.linking_context appeared)
- symlink transitive include directories under $EXT_BUILD_DEPS
- gather all possible transitive include directories to pass to CMake, pass transitive include directories to CMAKE_PREFIX_PATH so that the transitive include directories were scanned by CMake
- fix logic of passing transitive libraries into CPPFLAGS (configure_make)
- add test with the chain: Bazel lib -> CMake lib -> Bazel cc_test
- add synthetic configure-make test with the chain: Bazel lib -> configure_make lib -> Bazel cc_test
- also notice, that passed include directories from Bazel C/C++ Sandwich interface are not always existing; for now, make symlinking code resistant to that

* Windows, tests: fix for native test wrapper
In this PR:
- Update `@bazel_skylib` to 0.8.0, which has a
Windows-compatible unittest.bzl
- Fix unittest-using tests. Correct usage of
`unittest.end(env)` is to return its value.
Result: //test:all now passes with Bazel 0.25.0rc3
and --incompatible_windows_native_test_wrapper
* Register Skylib toolchains
* rules_foreign_cc_dep registers unittest toolchains
* Address review comments
* Add bazel_skylib_workspace to WORKSPACE files
* Remove stale toolchain init code
- explicitly pass the values of these options to corresponding compilation/link flags lists; add them to the end of the lists of they are not already there
- please see the test in test/standard_cxx_flags_test
* Improve outputs handling: wrapper script in shell-abstract manner
- extract wrapper script creation into a separate function,
- simplify the script and log names, also output the wrapper script text,
- introduce more shell primitives
related to #204
* Correct review comments
If the user passes empty string for some cache entry, for instance,
CMAKE_BUILD_TYPE, then the corresponding computed value
(computed from the Bazel's build type or Bazel C/C++ toolchain)
should not be used.
I.e., user passes "CMAKE_BUILD_TYPE": "", and there will be no
-DCMAKE_BUILD_TYPE in the cmake call.
Some configure scripts rely on being called from their parent directory (they call other files as if they are in the same directory). For this case, we should copy/symlink the contents of the directory under our build root, and run configure from there.
New attribute in configure_make rule: "configure_in_place".
Also, add documentation for configure_make.
* Register shell toolchain implementations in the correct order
so that the default implementation is the last
* Refactor shell toolchain to allow users register custom shell toolchains.
- define your own shell toolchain file(s) by copying @rules_foreign_cc//tools/build_defs/shell_toolchain/toolchains/impl:linux_commands.bzl,
and modifying the methods.
- create a mapping: a list of ToolchainMapping with the mappings between created file(s) and execution or/and target platform constraints.
- in the BUILD file of some package, call "register_mappings" macro from "@rules_foreign_cc//tools/build_defs/shell_toolchain/toolchains:defs.bzl", passing the mappings and toolchain_type_ = "@rules_foreign_cc//tools/build_defs/shell_toolchain/toolchains:shell_commands"
- in the WORKSPACE file of your main repository, when you initialize rules_foreign_cc, pass the mappings and the package, in which BUILD file you called "register_mappings" macro
* Correct typo
* Update README.md because of Bazel 0.22.0 release
- with Bazel 0.22.0, no flags are required to use rules_foreign_cc
- improve Bazel versions related information
- add link to "rules_foreign_cc take-aways"
* Correct headers in README
