By making the caller use the "namespace" keyword, the formatter
is given the right indentation hints.
Also makes it clearer synatactically. One day, this will be a
namespace alias (needs GCC 7).
Add a new CMake target, qa_all, which builds all
tests, tools and their deps.
Then, when KICAD_BUILD_QA_TESTS is set OFF, remove tests
and tools from the ALL target, so `make all` doesn't include
these builds.
This means even when you turn the KICAD_BUILD_QA_TESTS option
off, you still have the option to:
* Build individual tests: `make qa_pcbnew`
* Build all tests: `make qa_all_tests`
* Build all tools: `make qa_all_tools`
* Build all QA executables: `make qa_all`
This also will provide a place to hang extra logic for test routine
wrangling (e.g. by CI tools)
Update the "Compiling KiCad" dev docs.
Also, CMakeModules .cmake files should not be excluded from git
The SEXPR class is a useful general-purpose S-Expression library
class and can (maybe) be used else where. It also should get
test coverage, as even if noone else uses it, it's critical for the
kicad2step exporter.
Also add some test coverage for some kicad2step routines. For now,
they're not useful outside kicad2step, but they are at least a useful
reference for S-Expression parsing.
