300c7c7035 tests: stub out virfilewrapper.c on Win32
The Win32 platform can not do link time overrides in the same way
that we can on POSIX / ELF based platforms, so we cannot build
the virfilewrapper.c code reliably. Just stub it out on Win32
so it is a no-op. Tests that use this file are already written
to skip on Win32.

058bf5549f tests: fix virfilewrapper
If __lxstat() and __xstat() functions are not available, build fails with:

  CC       virfilewrapper.o
virfilewrapper.c:180:5: error: no previous prototype for function '__lxstat' [-Werror,-Wmissing-prototypes]
int __lxstat(int ver, const char *path, struct stat *sb)
    ^
virfilewrapper.c:208:5: error: no previous prototype for function '__xstat' [-Werror,-Wmissing-prototypes]
int __xstat(int ver, const char *path, struct stat *sb)

Luckily, we already check presence of these functions in configure
using AC_CHECK_FUNCS, so just don't wrap these if they're not available.

ae60ea48bc tests: Add virfilewrapper -- the new super "mock"
This mock (which is actually not mock at all, see later) can redirect
all accesses to a path into another path.  There is no need to
create mocks for particular directories, you just create a directory
with all the data a redirect the test there.

In the future, this should also be able to register callbacks for
calls/paths, e.g. when the test is going to write into anything under
"/sys/devices", call function fce();  Then in the open() call we would
add information about the fd into some structure and in write() we
would call fce() with parameters like @path to write to, @data to
be written and pointer to optional return value, so that fce() itself
could stop the call from happening or change its behaviour.  But
that's an idea for a latter day.

This is not a mock because it will not be preloaded, but compiled in
the test itself.  See future patches for usage.
