Modified files:
    contrib/dbsize : dbsize.c
    src/backend/access/transam: slru.c xlog.c
    src/backend/storage/file: fd.c
    src/include/storage: fd.h
    src/port       : copydir.c

Log message:
    Replace opendir/closedir calls throughout the backend with AllocateDir
    and FreeDir routines modeled on the existing AllocateFile/FreeFile.
    Like the latter, these routines will avoid failing on EMFILE/ENFILE
    conditions whenever possible, and will prevent leakage of directory
    descriptors if an elog() occurs while one is open.
    Also, reduce PANIC to ERROR in MoveOfflineLogs() --- this is not
    critical code and there is no reason to force a DB restart on failure.
    All per recent trouble report from Olivier Hubaut.
