89bc3f35e7 Userdata export: Reduce image size by 20 bytes. 
Replace an array of const char* literals with a single const char*
literal containing all the messages in the rotating prompt and an
array of alt_u8 containing the offsets of each message within the
literal.

This ends up yielding a larger size reduction than expected, a
healthy 20 bytes, despite a meager 8-byte difference in the size
of local variables and slightly more complex pointer math in
calculating the address of the current message within the string
literal.

32bbc49bf0 Userdata export: Fix menu behavior, particularly with the OSD. 
The behavior of the menu option was all over the place, and would
easily leave the OSD in a weird state, requiring the user to blindly
do something that completely redraws the OSD.

Fix this by making the behavior similar to that of the userdata import
feature, with the difference of giving a more specific error message
when something goes wrong.

b890446e3d Implement userdata export. 
A very simple implementation, as we are very short on remaining
block RAM. Simply blindly copies the entire userdata area to the
SD card. This may subject the SD card to some extra wear, as well
as potentially read-disturb some Flash memory pages, but this would
require more code.

53eedc9d08 sys_controller/Makefile: Add -flto to compiler/linker flags. 
This can (and does) considerably reduce the size of the resulting
binary, and as a bonus, the binary also does work. ;)

598705c7fa ulibSD/sd_io.c: Fix writing to SD card. 
There were a few things wrong with the SD card write implementation:
1. The protocol change regarding the interpretation of offsets
   introduced with SDHC cards was not taken into account in the write
   path, unlike in the read path.
2. All SPI writes involved in the process were actually issued as reads
   due to the use of the SPI_RW() function, the implementation of which
   seems to have gone through some churn. Likely just an instance of
   bit-rot.

71147c44dd Add 480x272 sampling/optimized mode for the PSP. 
This commit adds both a 480p input sampling mode and line2x optimized
mode for the PSP's 480x272 picture. The line2x optimized mode is enabled
automatically when the sampling mode is selected.

When in-game, the PSP outputs a letterboxed 480p picture. The active
portion of the screen is 480x272, but is treated as 480p (480x720).

In addition, a line2x optimized mode is added which produces a 960x544
output picture, which if desired the top + bottom pixels can be dropped
producing a 960x540 (qHD) picture.

To generate a qHD picture, use the following settings:

V. Active: 270
V. Backporch: 135

bab85e713b Increase max V. Backporch value from 63 to 236 
This change allows highly letterboxed content (e.g. the PSP's 480x272
picture in a 720x480 frame) to be "zoomed" to a full screen picture by
treating the letterbox as horizontal and vertical backporch.
