af83ed5c46 Write all ranges of neighbouring characters with the same width using the range notation in charmaps/UTF-8
Writing ranges of neighbouring characters with the same with like this

    <U000E0100>...<U000E01EF>	0

in charmaps/UTF-8 is more efficient than writing many single character lines
like:

    <U000E0100>	0
    <U000E0101>	0

4f3647e46e Prefer new libm function wrappers for !LIBM_SVID_COMPAT.
The initial obsoletion of SVID libm error handling left the old
wrappers and __kernel_standard still being used for new ports and
static linking, just with macro definitions of _LIB_VERSION and
matherr that meant symbols with those names were never actually used
and the code for different error handling variants could be optimized
out.

This patch cleans things up further by eliminating the
__kernel_standard use for new ports and static linking.  Now, the old
wrappers no longer generate any code in the !LIBM_SVID_COMPAT case,
while the new errno-only wrappers that were added for float128 support
are now also used for float, double and long double in that case.

The changes are generally straightforward.  The w_scalb*_compat
wrappers continue to be used (scalb is obsolescent in the sense of not
being supported for float128, but is present in supported standards -
the 2001 edition of POSIX and earlier XSI versions - so remains
supported for static linking and new ports, as do the float and long
double variants that are existing GNU extensions).  Those wrappers
would only call __kernel_standard in the _LIB_VERSION == _SVID_ case.
Since we would like to be able to compile most of glibc without
optimization, relying on a static function whose only use is under an
if (0) condition being optimized away to avoid an undefined
__kernel_standard reference may not be a good idea.  Thus, the
relevant code in the scalb wrappers has LIBM_SVID_COMPAT conditionals
added to guarantee it's not built at all in the case where
__kernel_standard does not exist.

Just as i386 has its own w_sqrt_compat.c, so w_sqrt.c is also added.
ia64 gets dummy w_*.c to prevent those files being built where they
would conflict with the ia64 libm, as with its existing w_*_compat.c.

Conditions disabling code for !LIBM_SVID_COMPAT are needed in both the
math/ wrappers and in the long double wrappers in ldbl-opt (to avoid
them setting up aliases and symbol versions for undefined symbols).  I
hope that future cleanups to how libm function aliases and symbol
versioning are done will eliminate the need for most of the ldbl-opt
wrappers.

Tested for x86_64 and x86, and with build-many-glibcs.py.

99d6791899 Fix pcprofiledump cross-endian condition (bug 22086).
debug/pcprofiledump.c contains code that tries to handle other-endian
data.  This uses a condition "(word & 0xfffffff0) == bswap_32
(0xdeb00000)".  This condition is always false (the LHS always has the
low four bits zero, the RHS doesn't); a correct comparison would use
0x0fffffff.  This results in -Werror=tautological-compare build
failures with the tile version of bits/byteswap.h and mainline GCC.

https://sourceware.org/ml/libc-testresults/2017-q3/msg00400.html

This patch fixes the condition.  Tested for x86_64, and with

5a80d39d0d Obsolete pow10 functions.
This patch obsoletes the pow10, pow10f and pow10l functions (makes
them into compat symbols, not available for new ports or static
linking).  The exp10 names for these functions are standardized (in TS
18661-4) and were added in the same glibc version (2.1) as pow10 so
source code can change to use them without any loss of portability.
Since pow10 is deliberately not provided for _Float128, only exp10,
this slightly simplifies moving to the new wrapper templates in the
!LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10,
pow10f and pow10l to be defined by those templates.

Tested for x86_64, and with build-many-glibcs.py.

e0d2eb5a79 linux: Implement tmpfile with O_TMPFILE (BZ#21530)
This patch adds O_TMPFILE support to tmpfile on Linux.  This is
similar to the previous suggestion by Andreas Schwab [1] with the
difference the file descriptor creation is parameterized to
compartmentalize Linux only open flags (O_TMPFILE) on sysdeps.

Checked on x86_64-linux-gnu.

	Andreas Schwab  <schwab@suse.de>

	[BZ #21530]
	* include/stdio.h (__gen_tempfd): New function.
	* stdio-common/Makefile (routines): Add gentempfd.
	* stdio-common/gentempfd.c: New file.

	* stdio-common/tmpfile.c (tmpfile): First try to use a system specific
