flash_eraseall.c: fix vda's breakage

- rephrase helptext for clarity

- improve wording

- by not calling getpagesize() twice we can save 2 bytes (walter harms)

- fix typo (thanks to Peter Kjellerstedt for noticing)

- Dual-license the config parser also under "LGLPv2.1 or later"
  (Vladimir Dronnikov)

make modutils compile again

depmod: accept and ignore -r (Linux kernle build needs this)

flash_eraseall: shrink

function                                             old     new   delta
flash_eraseall_main                                 1044    1006     -38

- add big busybox logo as transparent png

- bail out if screen resolution does not match PPM dimensions.
  Previously a 640x480 PPM on an e.g. 720x400 console would just segfault when
  reading the lines. While this bug should perhaps be fixed to handle such cases
  properly we just exit gracefully until somebody is willing to take care of it
  properly.

- document ppm header and skip whitespace

- update TODOs

- eliminate globals

- make it compile and shrink it a little bit (~-110 bytes)

- add some FIXMEs

- add flash_eraseall
This is the result after converting mtd-utils' flash_eraseall to BB.
The functionality given by this patch almost the same except that this
one does not support long options.
I needed this tool a system which does not have a lot of flash for RFS
and merging this into BB as the only way out.
