350b6eec4d New API: guestfs_blockdev_setra: Adjust readahead for filesystems and devices.
This adds a binding for 'blockdev --setra', allowing you to adjust the
readahead parameter for filesystems and devices.

dbdfa79d91 daemon: blockdev: Allow extraarg to be 0.
No change, since extraarg is not actually used.

4fc44a0157 blockdev: Deprecate blockdev_setbsz and make it do nothing (RHBZ#624334).
This call never did anything.  Don't use it.  Also I have submitted a
patch upstream to remove the corresponding option from blockdev.

See RHBZ#1002825 for an explanation of why this call was always
useless.

Thanks: Masayoshi Mizuma

0306c98d31 daemon: collect list of called external commands
guestfsd calls many different tools. Keeping track of all of them is
error prone. This patch introduces a new helper macro to put the command
string into its own ELF section:

GUESTFSD_EXT_CMD(C_variable, command_name);

This syntax makes it still possible to grep for used command names.

The actual usage of the collected list could be like this:

  objcopy -j .guestfsd_ext_cmds -O binary daemon/guestfsd /dev/stdout |
  tr '\0' '\n' | sort -u

The resulting output will be used to tell mkinitrd which programs to
copy into the initrd.

9e0b31a2af appliance: Set $PATH instead of hard-coding paths to binaries everywhere.
Change the appliance so PATH includes common directories.  Thus
we don't need to hard-code paths to binaries (eg. "/sbin/fdisk")
everywhere.

e9c3711310 daemon: Don't need to prefix error messages with the command name.
The RPC stubs already prefix the command name to error messages.
The daemon doesn't have to do this.  As a (small) benefit this also
makes the daemon slightly smaller.

Code in the daemon such as:

  if (argv[0] == NULL) {
    reply_with_error ("passed an empty list");
    return NULL;
  }

now results in error messages like this:

  ><fs> command ""
  libguestfs: error: command: passed an empty list

(whereas previously you would have seen ..command: command:..)

84fc760439 generator.ml: use new "Pathname" designation
Nearly every file-related function in daemons/*.c is affected:
Remove this pair of statements from each affected do_* function:
-  NEED_ROOT (return -1);
-  ABS_PATH (dir, return -1);
and change the type of the corresponding parameter to "const char *".
* src/generator.ml: Emit NEED_ROOT just once, even when there are two or
more Pathname args.
