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

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. daemon/augeas.c | 25 +-- daemon/blockdev.c | 24 +-- daemon/checksum.c | 5 daemon/cmp.c | 8 - daemon/command.c | 6 daemon/cpmv.c | 12 - daemon/daemon.h | 22 +-- daemon/debug.c | 2 daemon/devsparts.c | 4 daemon/df.c | 4 daemon/dir.c | 50 +------ daemon/du.c | 5 daemon/ext2.c | 28 +--- daemon/fallocate.c | 5 daemon/file.c | 59 +------- daemon/find.c | 5 daemon/fsck.c | 4 daemon/glob.c | 5 daemon/grep.c | 29 +--- daemon/grub.c | 6 daemon/guestfsd.c | 2 daemon/headtail.c | 13 - daemon/hexdump.c | 5 daemon/initrd.c | 5 daemon/inotify.c | 6 daemon/link.c | 17 -- daemon/ls.c | 10 - daemon/lvm.c | 30 +--- daemon/mknod.c | 11 - daemon/mount.c | 54 +++---- daemon/ntfs.c | 4 daemon/readdir.c | 5 daemon/realpath.c | 5 daemon/scrub.c | 14 -- daemon/sfdisk.c | 24 +-- daemon/stat.c | 15 -- daemon/strings.c | 7 - daemon/swap.c | 45 +----- daemon/tar.c | 14 -- daemon/upload.c | 6 daemon/wc.c | 11 - daemon/xattr.c | 39 ++--- daemon/zero.c | 4 daemon/zerofree.c | 4 src/generator.ml | 362 ++++++++++++++++++++++++++++++----------------------- 45 files changed, 430 insertions(+), 590 deletions(-)
