Convert the C code to using stdbool and true/false

Earlier we converted the C++ code to using true/false, and this converts
the C code to using the same style.

We already depended on stdbool.h in subsurfacestartup.[ch], and we build
with -std=gnu99 so nobody could build subsurface without a c99 compiler.

[Dirk Hohndel: small change suggested by Thiago Macieira: don't include
               stdbool.h for C++]
