- Use the fact that unicode code currently does not support chars above 0xffff
(see utf8decode()), and change diacritic database's char code type to
unsigned short from int. Also comment out database entries above unsupported
range.
- Use const when possible.
- Iterate over buffer using the buffer's pointer, thus avoiding usage of some
variables, and avoiding multiple access to the same array item.

- Fix bug which cause wrong placement of characters in some specific conditions
- Fix multiple similar entries in cache
- Protect against negative x values passed to drawing function

We had 3 different references to the same value. Rockbox always uses a blocksize of 512 bytes for SD and we were using SECTOR_SIZE, SD_BLOCK_SIZE, & card_info[drive].blocksize to use this value. Now the only reference being used is SD_BLOCK_SIZE.

This commit corrects the display of diacritic characters, which exist in many
languages. Hopefully, it will make Rockbox much more usable for users of these
languages.
Diacritic information (which used to decide whether a given character is
diacritic or not) is taken from the Unicode Standard, Version 5.2.
This feature does not affect drawing performance much, as the diacritic
database is cached (simple MRU mechanism).
There may be room for further performance, footprint, and
code-reuse wise improvements, that could be worked on in the future.

Patch by Boris Gjenero (dreamlayers). Writes are retried on failure now so this should be safe.

Writes will now be retried if they fail, and will be done using multisector transfers which should be faster.

Flyspray: FS#10371

Only enabled on e200v2 and Fuze (crashes on clipv1)

When read it returns all enabled interrupt sources
When written it enables interrupt sources for each bit set
So just like VIC_INT_EN_CLEAR, we don't have to read the previous value
before writing to it (VIC_INT_EN_CLEAR is write-only anyway)
Thanks to Fred Bauer for spotting

We don't need to check the FIFO for MCI_RX_ACTIVE because we don't experience problems reading from the SD cards.
We need the MCI_TX_ACTIVE FIFO check during writes because some SD cards spend longer times in the PRG state
programming the data that has been written to them.

We use wait_for_state() before any command that requires a state prior to being sent. Waiting after a transfer is not needed.

The crc check on responses to sd commands was being bypassed due to a SD_APP_OP_COND special case. Now a short response is returned
even if the crc check fails so we can check the busy bit. The send_cmd() function still returns a false value but it loads the response
variable with the cmd response.

- two essential parts of Sansa AMS drivers are optimzed away in newer gcc, so mark them volatile.
- use "r" instead of "i" (which is apparently invalid syntax) for the input list in some inline assembly
