This is the first patch in a series of patches to cleanup tree.h to
reduce the exposure it has all over the compiler.
In this patch, I'm moving functions that are used once into the files
that use them, and make them private to that file. These functions
were declared extern in tree.h and called from exactly one place.
The patch does not move EVERY function. This usually happens
when the function uses private state from its original file, and
moving that private state would mean moving other functions that made
no sense to move.
Additionally, the patch removes functions that were never used.
In subsequent patches, I will be moving out of tree.h extern definitions
that should be grouped in other files (e.g., all functions defined in
some FOO.c will be moved to the corresponding FOO.h). This will allow
me to remove the inclusion of tree.h from some files.
