This the first step into prefixing all symbol names in the simplicity static
library.

C has no name spaces, and we want to ensure there are no symbol collisions with
other libraries.

This prefixes most symbol names in the simplicity static library.

clang-rename is very finicky, so the following bash script was used:

shopt -s globstar

    clang-rename -i -qualified-name=${SYMBOL} -new-name=simplicity_${SYMBOL} $(grep "${SYMBOL}(" *.c *.h include/**/*.h primitive/**/*.c primitive/**/*.h -l) -- -I include
done

other libraries.

clang-rename cannot rename macro generated functions, so this must be done by hand.

This prefixes the rest of the symbol names in the simplicity static library.

other libraries.

All of the other exported symbols begin with the "simplicity_" prefix.
We are renameing the "elements_simplicty_" API functions to be
"simplicity_elements_" instead so that everything consistently has the same prefix.
