Corinna Vinschen e98d3eb3eb ctype: align size of category bit fields to small targets needs
E.g. arm ABI requires -fshort-enums for bare-metal toolchains.
Given there are only 29 category enums, the compiler chooses an
8 bit enum type, so a size of 11 bits for the bitfield leads to
a compile time error:

  error: width of 'cat' exceeds its type
    enum category cat: 11;
                  ^~~

Fix this by aligning the size of the category members to byte
borders.

Corinna Vinschen e186dc8661 towctrans_l: Always return a value from helper functions
touupper and toulower didn't return a value in all cases.  Worse,
this only broke Cygwin when building without optimization for debug
purposes.

Why GCC neglects to notice this is a mystery.

While at it, fix formatting.

Thomas Wolff c8d96a96ea make target for explicit Unicode data tables generation
Run 'make unidata' in newlib target directory to generate Unicode
data tables for libc functions wcwidth, tow* and isw*.

Thomas Wolff 41f72ab4d7 use generated character data
The tow* functions use an included case conversion table which can be
generated from Unicode data.
The isw* functions use a character categories table (provided by
categories.c) which can be generated from Unicode data.
Delegation between current-locale and specific-locale-dependent functions
was reverted towards the generic locale-dependent functions (*_l.c);
this is however only relevant on systems with non-Unicode wide character
locales, thus not on Cygwin.

Thomas Wolff f92f048528 Locale modifier @cjkwide to adjust ambiguous-width in non-CJK locales
Locale modifier @cjkwide makes Unicode "ambiguous width" characters
wide.  So ambiguous width characters can be enforced to have width 2
even in non-CJK locales. This gives e.g. users of "Powerline symbols"
the opportunity to adjust their width to the desired behaviour (and the
behaviour apparently expected by some tools) without having to set a CJK
locale and without losing consistence of terminal character width with
wcwidth/wcswidth locale width.

Thomas Preudhomme 7d09d0e261 Disable powf/log2?f/exp2?f optimization for single-precision Arm FPU
New optimized powf, logf, log2f, expf and exp2f yield worse performance
on Arm targets with only single precision instructions because the
double precision arithmetic is then implemented via softfloat routines.
This patch uses the old implementation when double precision
instructions are not available on Arm targets.

Testing: Built newlib with GCC's rmprofile Arm multilibs and compared
before/after -> only the above functions are changed and calls to them
(name change from logf to __ieee754_logf and similar). Testing the
changed function on a panel of values yields the same result before the
original patches to improve them and after this one. Double checking the
performance by looping the same panel of values being tested on Arm
Cortex-M4 does show the performance regression is fixed.
