This allows us to reuse this code for MinGW builds.
Additionally disable coverage step for Linux clang - it looks like
Travis has a mismatch in the version of gcov info between clang and gcov
which causes gcov to crash - somehow this crash isn't picked up as a
build error.
This commit changes sanitize configuration to fail on the first error
and ignore floating-point division and overflow "errors" that trigger
when we test the corresponding functionality. This makes it possible to
run this on all commits - if new UB or memory safety issues are introduced,
asan/ubsan will catch them.
codecov.io does not seem to support lcov regex customization;
additionally, we can't just replace unreachable with LCOV_LINE_EXCL
in gcov file - so we have to patch the ##### indicator (which suggests
the line hasn't been hit) with 1.

Use find -exec instead of xargs to work around differences between xargs on OSX
and Linux.
Use -b option of gcov - for some reason gcov on Travis can't find .gcno files
otherwise (old version?).
And finally enable config=coverage again.
This expands and replaces the Travis-specific makefile by adding more options and correctly tracking header dependencies.
Also add wchar_t mode test to Travis configuration.
