Instead of doing a recursive call into the src/ directory to build
the object files, hard link the source files into the daemon
directory and build them separately.
See:
http://www.redhat.com/archives/libguestfs/2009-November/msg00254.html
Thanks to Jim Meyering for noticing a typo in the original version.

This makes no functional change to the code. It just moves the
statvfs-related code out of daemon/stat.c into a new file called
daemon/statvfs.c.

The current groups are defined very conservatively using the
following criteria:
(a) Would be impossible to implement on Windows because of
sheer architectural differences (eg: mknod).
(b) Already optional (augeas, inotify).
(c) Not currently optional but not implemented on older RHEL and
Debian releases (ntfs-3g.probe, scrub, zerofree).
The optional groups I've defined according to these criteria are:
. augeas
. inotify
. linuxfsuuid
. linuxmodules
. linuxxattrs
. lvm2
. mknod
. ntfs3g
. scrub
. selinux
. zerofree
(Note that these choices don't prevent us from adding more
optional groups in future. On the other hand to avoid breaking
ABIs we would not wish to change the above groups).
The rest of this large commit is really just implementation:
Each optional function is classified using Optional "group"
flag in the generator.
The daemon has to implement a function
int optgroup_<name>_available (void);
for each optional group. Some of these functions are fixed at
compile time, and some do simple run-time tests.
The do_available implementation in the daemon looks up the correct
function in a table and runs it.
We document the optional groups in the guestfs(3) man page.
Also: I added a NOT_AVAILABLE macro in order to unify all the
existing places where we had a message equivalent to
"function __func__ is not available".

Start a new API allowing groups of functions to be tested for
availability.
There are two reasons for this:
(1) If libguestfs is built with missing dependencies (eg. no Augeas lib)
then the corresponding functions are disabled in the appliance. Up till
now there has been no way to test for this except to speculatively
issue commands and check for errors.
(2) When we port the daemon to Win32 it is likely that major pieces of
functionality won't be available (eg. LVM support). This API gives
a way to test for that.
There is no change for existing clients: you still have to check for
errors from individual API calls.
For new clients, you will be able to test for availability of particular
APIs.
Usage scenario (A): An LVM editing tool which requires
both the LVM API and inotify in order to function at all:
char *apis[] = { "inotify", "lvm2", NULL };
r = guestfs_available (g, apis);
if (r == -1) {
/* print an error and exit */
}
Usage scenario (B): A general purpose tool which optionally provides
configuration file editing, but this can be disabled, the result
merely being reduced functionality:
char *apis[] = { "augeas", NULL };
r = guestfs_available (g, apis);
enable_config_edit_menus = r == 0;

This change adds an explicit dependency on generator.ml for every file it
generates, except java files. Java is left for another time because it's
considerably trickier.
It also adds a build rule for src/libguestfs.la so it can be rebuilt as required
from other directories.
It does this by creating a top level make file, subdir-rules.mk, which can be
included from sub-directories. sub-directories need to define 'generator_built'
to include local files which are built by generator.ml, and they will be updated
automatically.
This fixes parallel make, and will automatically re-create generated files when
make is run from any directory.
It also fixes the problem which efad4f53 was targetting. Specifically,
src/guestfs_protocol.(c|h) had an erroneous dependency on stamp-generator, and
therefore generator.ml, despite not being directly created by it. This caused
them to be recreated every time generator.ml ran rather than only when
src/guestfs_protocol.x was updated, which cascaded into a daemon and therefore
appliance update.
This patch also changes the contents of the distribution tarball by including
files created by rpcgen.

This commit introduces a generic partition creation interface
which should be future-proof and extensible, and partially
replaces the old sfdisk-based interface.
The implementation is based on parted but is hopefully not too
dependent on the particulars of parted.
The following new calls are introduced:
guestfs_part_init:
Initialize a disk with a partition table. Unlike the sfdisk-
based interface, we also support GPT and other partition
types, which is essential to scale to devices larger than 2TB.
guestfs_part_add: Add a partition to an existing disk.
guestfs_part_disk:
Convenience function which combines part_init & part_add,
creating a single partition that covers the whole disk.
guestfs_part_set_bootable:
guestfs_part_set_name:
Set various aspects of existing partitions.
guestfs_part_list:
List partitions on a device. This returns a programming-friendly
list of partition structs (in contrast to sfdisk-l which cannot
be parsed).
guestfs_part_get_parttype:
Return the partition table type, eg. "msdos" or "gpt".
The following calls are planned, but not added currently:
guestfs_part_get_bootable
guestfs_part_get_name
guestfs_part_set_type
guestfs_part_get_type

truncate, truncate_size: Used to truncate files to a particular
size, or to zero bytes.
mkdir_mode: Like mkdir but allows you to also specify the
initial permissions for the new directory.
utimens: Set timestamp on a file with nanosecond accuracy.
lchown: Corresponding to lchown(2) syscall (we already have chown).
The implementation is complicated by the fact that we had to
add an Int64 parameter type to the generator.

* daemon/m4/gnulib-cache.m4: Add two modules: manywarnings, warnings.
* daemon/configure.ac: Implement --enable-gcc-warnings, and selectively
disable a few warning options that are either not useful or that provoke
too many warnings for now.
Define and AC_SUBST WARN_CFLAGS and WERROR_CFLAGS.
* daemon/Makefile.am (guestfsd_CFLAGS): Use $(WARN_CFLAGS)
and $(WERROR_CFLAGS), rather than just -Wall.

mkfs-b: Pass the -b (blocksize) parameter to mkfs.
mke2journal and friends: Lets you create external ext2 journals on
devices.
mke2fs-J and friends: Lets you create ext2/3/4 filesystems with
external journals.

* daemon/Makefile.am (SUBDIRS): Define.
(AM_CPPFLAGS): Define, to include from gnulib's lib/
(LDADD): Define, to link with gnulib's libgnu.a.
* daemon/configure.ac: Use AC_CONFIG_AUX_DIR([build-aux]),
gl_EARLY and gl_INIT.
(AC_CONFIG_FILES): Add lib/Makefile and tests/Makefile
* daemon/m4/gnulib-cache.m4: New file, generated by running
../.gnulib/gnulib-tool --import --with-tests hash
* daemon/.gitignore: Ignore all of the imported files.
build: tell bootstrap about daemon/
* bootstrap: Run gnulib-tool --update in daemon/.
Remove bootstrap's --gnulib-srcdir option, because it probably
didn't work, and even if it did, we've discovered that using
a separate git repo like that can lead to subtle mix-ups.

readlink command is used to read existing symbolic links.

This commit adds six calls to support Linux extended attributes.
They are:
getxattrs list all extended attributes for a file or directory
setxattr add/replace an extended attribute
removexattr remove an extended attribute
lgetxattrs \
lsetxattr (same as above, but operate on symbolic links)
lremovexattr /
See attr(5) for more information.
This also adds support for the FBuffer field type, which maps to
an XDR opaque<> or a C (int, char *) pair.

This patch allows you to do:
mkdir build
cd build
../configure ...
make
This will output all generated files to the build directory. Given that
autogen automatically runs configure, you can also do:
BUILDDIR=./build ./autogen.sh
which will do the right thing.
Also:
* Fix a dependency bug which means that guestfs_protocol.h
isn't automatically rebuilt.
* Re-running autogen.sh with no arguments won't blow away your previous
configure arguments.

This adds a readdir call (mostly intended for programs). The
return value is a list of guestfs_dirent structures.
This adds the new types 'struct guestfs_dirent' and
'struct guestfs_dirent_list', along with all the code to
return these in the different language bindings.
Also includes additional tests for OCaml and Perl bindings
to test this.

These commands are used to create block and char device
nodes or FIFOs (named pipes) in the filesystem.
The umask command is required also because the permissions
used by mknod are masked by the umask.
Also document and guarantee that the umask starts as 022.

command makes one with a label. The mkswap_U command makes one
with a known UUID.

initrd images. Update virt-inspector to use this instead of
the less efficient download/unpack locally method.
