15e5237469 storage: 64-bit sector offsets
* Create new 'sector_t' type alias:
    * uint64_t for all targets with HAVE_LBA48 or HAVE_SDUC
    * unsigned long for the everything else
 * Alter all storage APIs to use sector_t instead of 'unsigned long'
 * Alter Volume/Partition/storage info structures to use sector_t
 * Disk cache converted to sector_t
 * ATA Core:
    * convert to using sector_t for sector addresses and drive sizes
    * Always fill out upper 16 bits of LBA48 addresses
    * IDENTIFY INFO is fixed at 512 bytes, not SECTOR_SIZE
 * USB mass storage:
    * convert to using sector_t for sector addesses and drive sizes
    * Implement READ_16/WRITE_16 for LBA48 addresses
 * Convert FAT code to use sector_t for all sector references
 * output_dyn_value() now accepts int64_t instead of 'int'
 * Corrected "rockbox info" to work for (MULTIVOLUME & !MULTIDRIVE)
 * Better reporting of disk and (logical+physical) sector sizes in debug info
 * Detect SDUC cards and report on storage debug_info screen

To-do: SDUC

 * Refactor SD core to remove duplicate code in every driver
   * Card probe and init state machine
 * Implement core SDUC support
   * SD2.0 needs to be 2.0+ (fixed for jz47xx and x1000)
   * Host and Card ID (ACMD41)
   * 32-bit addressing for all read/write/erase operations (CMD22)
 * ADD SDUC to target device drivers, defining HAVE_SDUC as appropriate

1654efc313 Unify storage threads into one
* Editing a bunch of drivers' thread routines in order to
implement a new feature is tedious.

* No matter the number of storage drivers, they share one thread.
No extra threads needed for CONFIG_STORAGE_MULTI.

* Each has an event callback called by the storage thread.

* A default callback is provided to fake sleeping in order to
trigger idle callbacks. It could also do other default processing.
Changes to it will be part of driver code without editing each
one.

* Drivers may sleep and wake as they please as long as they give
a low pulse on their storage bit to ask to go into sleep mode.
Idle callback is called on its behalf and driver immediately put
into sleep mode.

* Drivers may indicate they are to continue receiving events in
USB mode, otherwise they receve nothing until disconnect (they
do receive SYS_USB_DISCONNECTED no matter what).

* Rework a few things to keep the callback implementation sane
and maintainable. ata.c was dreadful with all those bools; make
it a state machine and easier to follow. Remove last_user_activity;
it has no purpose that isn't served by keeping the disk active
through last_disk_activity instead.

* Even-out stack sizes partly because of a lack of a decent place
to define them by driver or SoC or whatever; it doesn't seem too
critical to do that anyway. Many are simply too large while at
least one isn't really adequate. They may be individually
overridden if necessary (figure out where). The thread uses the
greatest size demanded. Newer file code is much more frugal with
stack space. I barely see use crack 50% after idle callbacks
(usually mid-40s). Card insert/eject doesn't demand much.

* No forcing of idle callbacks. If it isn't necessary for one or
more non-disk storage types, it really isn't any more necessary for
disk storage. Besides, it makes the whole thing easier to implement.

a56f1ca1ed Cleanup MV/MD macros a little.
When using variadic macros there's no need for IF_MD2/IF_MV2 to deal
with function parameters. IF_MD/IF_MV are enough.

Throw in IF_MD_DRV/ID_MV_VOL that return the parameter if MD/MV, or 0
if not.
