Mass storage gadget returns DELAYED_STATUS in stead of
USB_GADGET_DELAYED_STATUS while handling bulk reset request. Since
peripheral driver uses USB_GADGET_DELAYED_STATUS for delayed status
handling, therefore replace DELAYED_STATUS by USB_GADGET_DELAYED_STATUS
in mass storage driver.
Since, DELAYED_STATUS and hence EP0_BUFSIZE will no longer be used now,
so remove them.

If cdrom flag is set ro flag is implied. Try setting the ro first, and
only if it succeeds set the cdrom flag.

This will be required by configfs integration.

Show/store methods for sysfs attributes contain code which can be used
also by configfs. Make them abstract the source the lun and rw_semaphore
are taken from.

When configfs is in place, the luns will not be represented in sysfs,
so there will be no struct device associated with a lun.
In order to maintain compatibility and allow configfs adoption
sysfs is made optional in this patch.
As a consequence some debug macros need to be adjusted. Two new
fields are added to struct fsg_lun: name and name_pfx.
The "name" is for storing a string which is presented to the user
instead of the dev_name. The "name_pfx", if non-NULL, is prepended
to the "name" at printing time.
The name_pfx is for a future lun.0, which will be a default group in
mass_storage.<name>. By design at USB function configfs group's creation
time its name is not known (but instead set a bit later in
drivers/usb/gadget/configfs.c:function_make) and it is this name that
serves the purpose of the said name prefix. So instead of copying
a yet-unknown string a pointer to it is stored in struct fsg_lun.

Converting to configfs requires making the f_mass_storage.c a module.
But first we need to get rid of "#include "storage_common.c".
This patch makes storage_common.c a separately compiled file, which is
built as a utility module named u_ms.ko. After all mass storage users are
converted to the new function interface this module can be eliminated
by merging it with the mass storage function's module.
USB descriptors are exported so that they can be accessed from
f_mass_storage.
FSG_VENDOR_ID and FSG_PRODUCT_ID are moved to their only user.
Handling of CONFIG_USB_GADGET_DEBUG_FILES is moved to f_mass_storage.c.
The fsg_num_buffers static is moved to FSG_MODULE_PARAMETER users, so
instead of using a global variable the f_mass_storage introduces
fsg_num_buffers member in fsg_common (and fsg_config).
fsg_strings and fsg_stringtab are moved to f_mass_storage.c.
