add memmem()
memmem() is a nice GNU extension for searching a length limited string
in another one.
This compat version is based on the version found in glibc 2.2 (GPL 2);
I only removed the optimization of checking the first char by hand, and
generally tried to keep the code simple. We can add it back if memcmp
shows up high in a profile, but for now I prefer to keep it (almost
trivially) simple.
Since I don't really know which platforms beside those with a glibc
have their own memmem(), I used a heuristic: if NO_STRCASESTR is set,
then NO_MEMMEM is set, too.
