Update headers for Linux 3.15.
This patch updates glibc headers for changes / new definitions in
Linux 3.15. In the course of my review I noticed that
IPV6_PMTUDISC_INTERFACE was absent from glibc despite the inclusion of
IP_PMTUDISC_INTERFACE; I added it along with IP_PMTUDISC_OMIT and
IPV6_PMTUDISC_OMIT. I did not add FALLOC_FL_NO_HIDE_STALE given the
kernel header comment that it is reserved.
Tested x86_64.
* sysdeps/unix/sysv/linux/bits/fcntl-linux.h [__USE_GNU]
(FALLOC_FL_COLLAPSE_RANGE): New macro.
[__USE_GNU] (FALLOC_FL_ZERO_RANGE): Likewise.
* sysdeps/unix/sysv/linux/bits/in.h (IP_PMTUDISC_OMIT): Likewise.
(IPV6_PMTUDISC_INTERFACE): Likewise.
(IPV6_PMTUDISC_OMIT): Likewise.
Only the sysdeps/unix/sysv/linux/bits/in.h part is backported in this
patch. The sysdeps/unix/sysv/linux/bits/fcntl-linux.h part was
completely superseded by glibc-rh1476120.patch, which uses
<linux/falloc.h> in favor of duplicated constants.
