1. Minor fix for JCL_realloc() (don't call free(ptr) if ptr is null like in JCL_free);
2. 32/64-bit code variants collapsed by introducing several macros (which select the proper class name, primitive type, etc.);
3. new recognized macro (JCL_NO_JNIONLOAD) which removes the need for JNI_OnLoad (thus, if JCL_NO_JNIONLOAD is defined, it is
possible to link jcl.c statically).
