Using madvise with MADV_DONTNEED to release memory back to the kernel
is not sufficient to change the commit charge accounted against the
process on Linux. It is OK however, when overcommit is enabled or is
heuristic. However, when overcommit is restricted to a percentage of
memory setting the contents of /proc/sys/vm/overcommit_memory as 2, it
makes a difference since memory requests will fail. Hence, we do what
we do with secure exec binaries, which is to call mmap on the region
to be dropped with MAP_FIXED. This internally unmaps the pages in
question and reduces the amount of memory accounted against the
process.

The ttyname and ttyname_r functions on Linux now fall back to
searching for the tty file descriptor in /dev/pts or /dev if /proc is
not available. This allows creation of chroots without the procfs
mounted on /proc.
Fixes BZ #14516.
Initially based on the versions found in wcsmbs/* ; these files have
been changed by hand unrolling, and adding some additional variables
to allow some read-ahead to occur, which then relieves some of the
wait-for-increment/wait-for-load/wait-for-compare-results pressure
that was slowing down every iteration through the while-loop.
For 64-bit Power7, These changes give an approx 20% throughput boost
for the wcschr and wcsrchr functions; and approx 40% boost for the
wcscpy function. 32-bit improvements appear to be slightly better
with ~ %30 and ~ %45 respectively. Results for Power6 closely match
those for power7.
Assorted tweaking, twisting and tuning to squeeze a few additional cycles
out of the memchr code. Changes include bypassing the shift pairs
(sld,srd) when they are not required, and unrolling the small_loop that
handles short and trailing strings.
Per scrollpipe data measuring aligned strings for 64-bit, these changes
save between five and eight cycles (9-13% overall) for short strings (<32),
Longer aligned strings see slight improvement of 1-3% due to bypassing the
shifts and the instruction rearranging.
The original runtime linker auditing interface described
by Solaris allows the 5th argument of la_pltenter() to be
modified. This patch cleans up the ldsodefs.h definitions
such that the 5th argument is not constant.
At one point the 5th argument *was* constant but this was
changed with commit 2413fdba7a.
This patch updates alpha, ia64, mips, sh and sparc with similar
changes.

* sysdeps/i386/i686/multiarch/strcmp-sssse3.S: Fix
segmentation fault for a case of two empty input strings.
* string/test-strncasecmp.c (check1): Renamed to...
(bz12205): ...this.
(bz14195): Add new testcase for two empty input strings and N > 0.
(test_main): Call new testcase, adapt for renamed function.
Pretty sure we require recent enough versions of gcc/binutils to make this
check pointless. I can't any logs in the last few years where this check
didn't return "yes".

(__ptrace_eventcodes): Add new value PTRACE_EVENT_SECCOMP from Linux 3.5.
(__ptrace_setoptions): Add new value PTRACE_O_TRACESECCOMP, adjust PTRACE_O_MASK.
- make LOGIN non-static, as it would make getlogin_r no more reentrant; change its type to string_t
- fail with ERANGE if NAME has not enough space for the actual login string
- copy with memcpy only the chars of the string
Create a new create_address_port subroutine to isolate the address port creation
(for both local and remove sockets), and use it inside HURD_DPORT_USE.
Also intialize APORT to MACH_PORT_NULL and make sure to always deallocate it,
when not null.
Add support for STT_GNU_IFUNC symbols and the new R_390_IRELATIVE
relocation. Provide optimized version of memcpy, memset, and memcmp
for z10 and z196.
