Checking for errors in the file rename step

[adammoody]

AXL_Test is only meant to tell the caller whether calling AXL_Wait will block or not. The caller must always call AXL_Wait whether they have called AXL_Test or not. We don't want AXL_Test to do any "complete" work, it should only check and report status. Thus, we don't want to rename files here:

AXL/src/axl.c

Line 789 in d738fb7

axl_rename_files_to_final_names(id);

Also, we should consider a failed rename call to be a failed transfer. We should detect and report errors there, since it could mean that the temporary file never actually changed to the final file name:

AXL/src/axl.c

Line 723 in d738fb7

rename(dst, newdst);

We might also want to consider a transfer to have failed if we fail to copy the metadata:

AXL/src/axl_io.c

Line 615 in d738fb7

axl_meta_apply(dst_file, meta);

Resolved with #80

Oh, wait. The metadata issue is still unresolved. Will keep this open until that's also addressed.
