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.
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.

Kill config options by making them always on:
FEATURE_HTTPD_RELOAD_CONFIG_SIGHUP
FEATURE_HTTPD_CONFIG_WITH_MIME_TYPES
This makes httpd.c remotely readable - it had ~125 #ifdefs, now it has ~100.
The growth on a .config with all FEATURE_HTTPDs off is:

without it, determination of remaining lease time is unreliable.
Yes, it's costly in code size, but without it, dumpleases output
is misleading!

Lots of nasty, but hard to trip, races are fixed.
