I've checked in the changes to mark the release of version 2.9.  The
tree is not yet tagged, I'm waiting a short while to see whether there
are any brown bag bugs to fix.  The code has been extensively tested as
part of Red Hat's rawhide development.

There is one known potential problem with the name resolving which has
been extensively changed.  Under some circumstance (always involving
broken servers) requests are not completely processed.  Often a second
call fixes the problem.  This might be fixed in the latest code, maybe
not.  Unfortunately no reported has been able or willing to provide the
information needed to track down the problem.

Anyway, the user-visible change for this release include:

* Unified lookup for getaddrinfo: IPv4 and IPv6 addresses are now looked
  up at the same time.  Implemented by Ulrich Drepper.

* TLS descriptors for LD and GD on x86 and x86-64.
  Implemented by Alexandre Oliva.

* getaddrinfo now handles DCCP and UDPlite.
  Implemented by Ulrich Drepper.

* New fixed-size conversion macros: htobe16, htole16, be16toh, le16toh,
  htobe32, htole32, be32toh, le32toh, htobe64, htole64, be64toh, le64toh.
  Implemented by Ulrich Drepper.

* New implementation of memmem, strstr, and strcasestr which is O(n).
  Implemented by Eric Blake.

* New Linux interfaces: inotify_init1, dup3, epoll_create1, pipe2

* Implement "e" option for popen to open file descriptor with the
  close-on-exec flag set.  Implemented by Ulrich Drepper.

* Implement "b" mode for fmemopen.  In this mode writes writes don't
  implicitly add a NUL byte and seeks from the end of the buffer really
  use the buffer end, not the string length as the basis.
  Implemented by Ulrich Drepper.

* Many functions, exported and internal, now atomically set the
close-on-exec
  flag when run on a sufficiently new kernel.  Implemented by Ulrich
Drepper.

* Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu,
  Sinhala)
  Implemented by Pravin Satpute.

* New locales: sd_IN, sd_IN@devanagari, ks_IN@devanagari, ht_HT, en_AG,
nl_AW.
