dup2: fix more mingw problems

* lib/dup2.c (rpl_dup2) [_WIN32]: Avoid hanging when duplicating
fd to itself.
* doc/posix-functions/dup2.texi (dup2): Document the bug.
* lib/unistd.in.h (dup2) [REPLACE_FCHDIR]: Avoid name collision.
* lib/fchdir.c (dup2): Manage preprocessor macros correctly.
(rpl_dup2_fchdir): Rename from rpl_dup2, and let dup2 module take
care of mingw bugs.
