fsck: add refs report function

Browse source 
Introduce a new struct "fsck_ref_report" to contain the information we
need when reporting refs-related messages.

With the new "fsck_vreport" function, add a new function
"fsck_report_ref" to report refs-related fsck error message. Unlike
"report" function uses the exact parameters, we simply pass "struct
fsck_ref_report *report" as the parameter. This is because at current we
don't know exactly how many fields we need. By passing this parameter,
we don't need to change this function prototype when we want to add more
information into "fsck_ref_report".

We have introduced "fsck_report_ref" function to report the error
message for refs. We still need to add the corresponding callback
function. Create refs-specific "error_func" callback
"fsck_refs_error_function".

Last, add "FSCK_REFS_OPTIONS_DEFAULT" macro to create default options
when checking ref consistency.
