unix: Fix behaviour of COPT/NDEBUG for unix variants. Based on eg 1e6fd9f2b4072873f5d6846b19b2ef0ccc5e4e52, it's understood that the intention for unix builds is that regular builds disable assert, but the coverage build should set -O0 and enable asserts. It looks like this didn't work (even before variants were introduced, eg at v1.11) -- coverage always built with -Os and -DNDEBUG. This commit makes it possible for variants to have finer-grained control over COPT flags, and enables assert() and -O0 on coverage builds. Other variants already match the defaults so they have been updated.

unix: Add build variants, analogous to boards on bare-metal. Invoking "make" will still build the standard "micropython" executable, but other variants are now build using, eg, "make VARIANT=minimal". This follows how bare-metal ports specify a particular board, and allows running any make target (eg clean, test) with any variant. Convenience targets (eg "make coverage") are provided to retain the old behaviour, at least for now. See issue #3043.

unix/Makefile: Reserve CFLAGS_EXTRA/LDFLAGS_EXTRA for external use. When CFLAGS_EXTRA/LDFLAGS_EXTRA (or anything) is set on the command line of a make invocation then it will completely override any setting or appending of these variables in the makefile(s). This means builds like the coverage variant will have their mpconfigvariant.mk settings overridden. Fix this by using CFLAGS/LDFLAGS exclusively in the makefile(s), reserving the CFLAGS_EXTRA/LDFLAGS_EXTRA variables for external command-line use only.

all: Enable extra conversion warnings where applicable. Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out implicit floating point conversions, and add extra Travis builds using MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found previously. For the unix port -Wsign-comparison is added as well but only there since only clang supports this but gcc doesn't.

examples/usercmodules: Simplify user C module enabling. It's a bit of a pitfall with user C modules that including them in the build does not automatically enable them. This commit changes the docs and examples for user C modules to encourage writers of user C modules to enable them unconditionally. This makes things simpler and covers most use cases. See discussion in issue #6960, and also #7086. Signed-off-by: Damien George <damien@micropython.org>

unix: Make manifest selection match other ports. Changes are: - The default manifest.py is moved to the variants directory (it's in "boards" in other ports). - The coverage variant now uses a custom manifest in its variant directory to add frzmpy/frzstr. - The frzmpy/frzstr tests are moved to variants/coverage/.

examples: Add example code for user C modules, both C and C++. Add working example code to provide a starting point for users with files that they can just copy, and include the modules in the coverage test to verify the complete user C module build functionality. The cexample module uses the code originally found in cmodules.rst, which has been updated to reflect this and partially rewritten with more complete information.
