During migration of dev-lua/* ebuilds to slotted lua, I noticed, that
many ebuilds use 'dev-lua/busted' for running tests. This change adds
support for running a test-runner, at first only 'busted' for now.
Also a non-color and plaintext output will be used for the test-runner 'busted'.
This is basically a copy of the test-runner section, written by mgorny,
which already exists in 'distutils-r1', but modified and adapted to lua.
In order to use this feature, you can define 'lua_enable_tests busted'
to setup everything needed for tests and run them. By default,
'dev-lua/busted' assumes, that tests are in the 'spec' folder.
If this is not the case, you can add a second argument to specify a
different folder. For example, if the folder is called 'foo', you can
just run 'lua_enable_tests busted foo'.
More test-runners can be added in future, if needed.
PATCH v2 has two changes:
- removed EAPI condition, as lua-utils is EAPI=7 only.
- make test_directoy as a local variable and use eval in src_test to
read it.
PATCH v3 has the right patch, as v2 was wrong.

+# @FUNCTION: lua_enable_tests
+# @USAGE: <test-runner> <test-directory>
+# @DESCRIPTION:
+# Set up IUSE, RESTRICT, BDEPEND and src_test() for running tests
+# with the specified test runner. Also copies the current value
+# of RDEPEND to test?-BDEPEND. The test-runner argument must be one of:
+#
+# - busted: dev-lua/busted
+#
+# Additionally, a second argument can be passed after <test-runner>,
+# so <test-runner> will use that directory to search for tests.
+# If not passed, a default directory of <test-runner> will be used.
+#
+# - busted: spec
+#
+# This function is meant as a helper for common use cases, and it only
+# takes care of basic setup. You still need to list additional test
+# dependencies manually. If you have uncommon use case, you should
+# not use it and instead enable tests manually.
+#
+# This function must be called in global scope, after RDEPEND has been
+# declared. Take care not to overwrite the variables set by it.
