Replace all calls to access by gnupg_access

Browse source 
* common/sysutils.c (gnupg_access): New.  Replace all calls to access
by this wrapper.
* common/homedir.c (w32_shgetfolderpath): Change to return UTF-8
directory name.
(standard_homedir): Adjust for change.
(w32_commondir, gnupg_cachedir): Ditto.

Also use SHGetFolderPathW instead of SHGetFolderPathA on Windows.

This is required to correctly handle non-ascii filenames on Windows.
