[Libguestfs] [PATCH 0/23] factor and const-correctness

[Jim Meyering]

This started as a simple warning-elimination change.
I'll get back to that series shortly ;-)
It turned into a factorization and constification exercise
during which I got a taste of ocaml.  Thanks to Rich Jones
for help with a few snippets in generator.ml.

The overall result is that many previously-manually-maintained
bits from daemon/*.c functions are now hoisted into the automatically-
generated (by generator.ml) file, stubs.c.  Now, many of the
interfaces in daemon/*.c (with declarations in the autogenerated
file, daemon/actions.h) that were not const-correct are.
