The buffer is to be overwritten anyway, so there's no need to preserve its
contents.  Also, the old code leaked if the realloc were to fail.  All in all,
free-then-alloc is simpler.

kernel32/tests: Change to a win_skip() because we don't want to skip the GetConsoleCursorInfo(,NULL) test in Wine.

Add typegen_detect_type for detecting types useful during
client/server/proxy code generation.

widl: Use type_get_type to determine the types of types during C client, server and proxy code generation.

Use type_get_type and friends instead.

gdi32/tests: Don't test the height that is 1.75 times the original font height. This is unscaled in winnt yet doubled in win9x.

We can't assume that wctomb(Unicode default char) is identical to the Ansi
default char.
