AdvaImg:

- freeimage extracted to the separate library;
- FI_INTERFACE removed, all references to it are replaced with direct calls of FreeImage_* functions;
- unified project for AdvaImg

+ * This routine is in charge of selecting the modules to be executed and
+ * making an initialization call to each one.
+ *
+ * Logically, this code belongs in jcmaster.c.  It's split out because
+ * linking this routine implies linking the entire compression library.
+ * For a transcoding-only application, we want to be able to use jcmaster.c
+ * without linking in the whole library.
