Subject: [PATCH v2] Extend win32 error codes to errno mapping in win32error.c

The doserrors[] table in win32error.c maps win32 error codes to
errno so that the errors get handled uniformly by the callers
across postgres code in a platform-independent way. The mapping
table has covered the most common win32 errors, however, it
missed ERROR_INVALID_NAME which gets emitted when the file name,
directory name, or volume label syntax is incorrect. This error
on win32 platforms is easy to hit - for instance, sending a
malformed file name to open() system call.

The closest mapping for ERROR_INVALID_NAME is ENOENT, this commit
adds it to the doserrors[] mapping table.
