This patch implements all ioctls currently implemented by device mapper,
enabling us to run dmsetup and kpartx inside of linux-user.

DirectFB-1.0 uses at least two of the four added ioctls, and the two
others were added for completeness. This patch was validated with the
program "vlock -all/-new".

The result needs to be converted as it is stored in an array of struct
ifreq and sizeof(struct ifreq) differs according to target and host
alignment rules.
This patch allows to execute correctly the following program on arm
and m68k:
#include <stdio.h>
#include <sys/ioctl.h>
#include <net/if.h>
#include <alloca.h>
#include <string.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
int main(void)
{
int s, ret;
struct ifconf ifc;
int i;
memset( &ifc, 0, sizeof( struct ifconf ) );
ifc.ifc_len = 8 * sizeof(struct ifreq);
ifc.ifc_buf = alloca(ifc.ifc_len);
s = socket( AF_INET, SOCK_DGRAM, 0 );
if (s < 0) {
perror("Cannot open socket");
return 1;
}
ret = ioctl( s, SIOCGIFCONF, &ifc );
if (s < 0) {
perror("ioctl() failed");
return 1;
}
for (i = 0; i < ifc.ifc_len / sizeof(struct ifreq) ; i ++) {
struct sockaddr_in *s;
s = (struct sockaddr_in*)&ifc.ifc_req[i].ifr_addr;
printf("%s\n", ifc.ifc_req[i].ifr_name);
printf("%s\n", inet_ntoa(s->sin_addr));
}
}

In case a chrooted build uses XEN or KVM, a looped mount needs to be done to setup the chroot.
The ioctl for loop mount works correctly for arm, mips, ppc32 and sh4, so its now activated.

Add a configure check for the existence of linux/fiemap.h and the
IOC_FS_FIEMAP ioctl. This fixes a compilation failure on Linux
systems which don't have that header file.

Implement the FS_IOC_FIEMAP ioctl using the new support for
custom handling of ioctls; this is needed because the struct
that is passed includes a variable-length array.
