This addresses a long standing collision between userspace headers and
kernel headers only on ia64 systems. All other types have a __ prefix
in the ptrace headers except these two. Let's finally namespace these.
Verified that at least strace still builds after this change, as well
as after deleting all the struct hacks it has specifically for ia64.

All the other ptrace structures in this file have a __ prefix except this
new one. This in turn causes build problems for most packages that try to
use ptrace such as strace:
gcc -DHAVE_CONFIG_H -I. -I../.. -I../../linux/x86_64 -I../../linux \
-I./linux -Wall -Wwrite-strings -g -O2 -MT process.o -MD -MP \
-MF .deps/process.Tpo -c -o process.o ../../process.c

Since this struct was introduced in glibc-2.18, there shouldn't be any
real regressions with adding the __ prefix.

The sp check has to be moved up to the start of the func since it now
makes a system call and that'll clobber a lot of registers.

The new tst-setjmp-fp test has been failing on IA64 because the setjmp
and longjmp helpers take care of saving/restoring the fpsr register.
Per the C standards, this is incorrect, so disable that logic.

Rather than opencode the __GI_xxx logic, use proper hidden helpers.

This file has a few #if 0 code paths which cause a build time warning:
ports/sysdeps/unix/sysv/linux/ia64/ioperm.c:66:7: warning:
variable 'prot' set but not used [-Wunused-but-set-variable]
Rather than add more #if 0 around that variable, just delete the code
altogether. Not like it's going to ever be implemented.

Autoconf has been deprecating configure.in for quite a long time.
Rename all our configure.in and preconfigure.in files to .ac.

This function is now called from dl_open_worker with the GL(dl_load_lock)
lock held and no longer needs local protection. GL(dl_load_lock) also
correctly protects _dl_lookup_symbol_x called here that relies on the
caller to have serialized access to the data structures it uses.

This patch introduces two new convenience functions to set the default
thread attributes used for creating threads. This allows a programmer
to set the default thread attributes just once in a process and then
run pthread_create without additional attributes.

These macros often set up a variable that later macros sometimes do
not use. Add unused attribute to avoid that.
Similarly, the ia64 code tends to check the err field rather than
the val (which is opposite of most arches) leading to the same
kind of warning. Replace this with a dummy reference.

Function pointers on ia64 are like parisc -- they're plabels. While
the parisc port enjoys a gcc builtin for extracting the address here,
ia64 has no such luck.
Casting & dereferencing in one go triggers a strict aliasing warning.
Use a union to fix that.

The ia64_rse_is_rnat_slot func expects an unsigned pointer, but we're
passing in a signed pointer. The signness doesn't matter here, so
convert it to unsigned.

The recent change to clean up these defines missed the ia64 logic.

This feature is specifically for the C++ compiler to offload calling
thread_local object destructors on thread program exit, to glibc.
This is to overcome the possible complication of destructors of
thread_local objects getting called after the DSO in which they're
defined is unloaded by the dynamic linker. The DSO is marked as
'unloadable' if it has a constructed thread_local object and marked as
'unloadable' again when all the constructed thread_local objects
defined in it are destroyed.

Since we no longer support __ASSUME_POSIX_CPU_TIMERS, the ia64 code
no longer needs to override HAS_CPUCLOCK in the common file. Drop
the ia64 shim as well.
