This patch cleans up some unneeded code. Releases some allocated
memory before the compiler quits and fixes a couple minor memory
leaks in the compiler and vvp code generator.
Remove the #ident and $Log$ strings from all the header files and
almost all of the C/C++ source files. I think it is better to get
this done all at once, then to wait for each of the files to be
touched and edited in unrelated patches.
