The default music directory has been changed to /sdcard/music anyway, so
it is no longer required and actually more confusing to people, since
they will think they should put their music into ~/music, which will not
work with the default configuration of mpd.
The platform headers has the following macro:
#define MB_CUR_MAX __ctype_get_mb_cur_max()
where __ctype_get_mb_cur_max() tries to handle UTF-8 encodings.
However, even in Android 7.0 setlocale(LC_ALL, ""), which many
programs do at startup, doesn't work in that it sets the locale
as non-utf8:
https://android.googlesource.com/platform/bionic/+/nougat-release/libc/bionic/locale.cpp#139
So we just always consider us being in an utf-8 locale.
Also rebuild coreutils to fix#1136.
cat{open,close,gets} has been removed from libandroid-support as
they were just stubs there anyway. imagemagick manages fine without
them but needs to be rebuilt with its revision bumped.
This will make things as std::to_string() and other C++ features
work with a modern and supported C++ library.
We package up libc++_shared.so and bump the revision of every C++
using package to make it rebuild against it.
Users who have built C++ using libraries or programs will probably
need to rebuild them if they are linked against Termux-supplied
libraries, as user code was previously linked against gnustl while
the system libraries are now using libc++, and it's not a good idea
to mix C++ standard libraries in a program.
