I found lots of places where we assume error will be set when calling one of our virtualised functions, such as db_open(), but error is only set when a system call fails, and it is not uncommon for us to fail a function internally without ever making a system call. That led to us passing back success when a function had in fact failed. I found two places where we relied on map_nt_error_from_unix() returning success when errno==0, but lots and lots of places where we relied on the reverse, so I fixed those two places. map_nt_error_from_unix() will now always return an error, returning NT_STATUS_UNSUCCESSFUL if errno is 0 (cherry picked from commit 69d40ca4c1af925d4b0e59ddc69ef8c26e6501d1) (This used to be commit 834684a524a24bb4eb46b4af583d39947dc87d95)

s3-lib Remove unused dos error codes from errmap_unix This also makes unix_nt_errmap private to errmap_unix.c and errormap.c so the tables themselves cannot be duplicate symbols until merged. Andrew Bartlett
