d0b72e2590 GSoC/Buflib: Add buflib memory alocator to the core. 
The buflib memory allocator is handle based and can free and
compact, move or resize memory on demand. This allows to effeciently
allocate memory dynamically without an MMU, by avoiding fragmentation
through memory compaction.

This patch adds the buflib library to the core, along with
convinience wrappers to omit the context parameter. Compaction is
not yet enabled, but will be in a later patch. Therefore, this acts as a
replacement for buffer_alloc/buffer_get_buffer() with the benifit of a debug
menu.

See buflib.h for some API documentation.

bdb5974c0e Revert r21912 : "Storage API : remove undeeded target-specific functions" 
After a discussion mixed on mailing list and irc, it was agreed that
more abstraction for plugins is better (so developers don't have to add
a check to HAVE_DISK_STORAGE when writing disk-specific code)

8eba69f91b Storage API : remove undeeded target-specific functions 
storage_sleep, storage_spin, storage_spindown are only defined if #defiend (HAVE_DISK_STORAGE), not for MMC/ATA/SD
remove already unneeded nand_disk_is_active, nand_soft_reset

9f6e117e82 TCC NAND: The BLOCKS_PER_SEGMENT define was actually the number of planes mentioned in the Samsung NAND datasheet. Add this to the nand_id struct, so that it can be runtime detected (required for some D2s to boot). Use the struct directly instead of making a local copy, and format the nand_info table to 80 columns.

93f3367f42 Telechips NAND: much improved read reliability on D2/iAudio7. More work is required for M200/DAX, but an improvement is evident nonetheless. LPT buffers are now buffer_alloc'd after determining the required size, so most targets should also see a healthy reduction in RAM usage.

2f8a0081c6 Apply FS#9500. This adds a storage_*() abstraction to replace ata_*(). To do that, it also introduces sd_*, nand_*, and mmc_*. 
This should be a good first step to allow multi-driver targets, like the Elio (ATA/SD), or the D2 (NAND/SD).

d462a64a91 Initial commit of iaudio 7 port by Vitja Makarov (FS#9245). Port is at quite an advanced stage, but is troubled by the lack of a reliable NAND driver (similar to the Cowon D2 port) and is not yet suitable for non-developers.

ee72b3bbc6 Make the TCC780x NAND driver also build for 77x targets. This is work-in-progress stuff and does not yet work fully on 77x, but it's a step in the right direction. Also replace some magic numbers with #defines.
