Prefix symbols from stb_image.h 

This makes it possible to link assimp statically into an executable with
another static library that includes stb_image.h without hiding its
symbols.

/* Use prefixed names for the symbols from stb_image as it is a very commonly embedded library.
Including vanilla stb_image symbols causes duplicate symbol problems if assimp is linked
statically together with another library or executable that also embeds stb_image.
Symbols are not prefixed if using Hunter because in such case there exists a single true
stb_image library on the system that is used by assimp and can be used by all the other
libraries and executables.
The list can be regenerated using the following:
cat <path/to/stb/stb_image.h> | fgrep STBIDEF | fgrep '(' | sed -E 's/\*|\(.+//g' | \
awk '{print "#define " $(NF) " assimp_" $(NF) }' | sort | uniq"
