WINEDEBUG=+all,-relay extract

During installation of proplusww.msi, a part of the Microsoft Office 2013
installer, via direct invocation of msiexec, the second Cabinet file is
mishandled, resulting in an installation failure and rollback.

At lines 11-24, the installer is seen accessing ProPsWW.CAB twice, then
following the MEDIA table lookup, at lines 981-988 it changes focus to
ProPsWW2.CAB but only accesses it once.

During a successful install on 1.7.22, the WINEDEBUG for both CAB files read
similarly. The ISO was mounted on /dev/loop0, during both successful and
unsuccessful installations.

I don't have the 1.7.22 WINEDEBUG, but if absolutely necessary I can
re-generate it.

In addition, at lines 1194-1195 a CDROM_SyncCache (ISO) error occurs. I don't
know whether the 1.7.22 WINDEBUG contained this.

I haven't had time to perform a bisect, but since 1.7.22 a change was made in
1.7.45 to the handling of CABs and so I have highlighted the commit which I
anticipate is the cause of the issue.

I haven't investigated any changes between 1.7.22 and 1.7.48 to the cdrom
module.
