libs/libc/stdio/lib_libvsprintf.c: Resolves the integer field width problem if Issue 35 for the cases of long and long long integer types.
libs/libc/stdio/lib_libvsprintf.c: Resolves the integer field width problem if Issue 35 for the case of integer types.
libs/libc/stdio: Remove CONFIG_NOPRINTF_FIELDWIDTH. That option does, indeed, make the printf family of functions much smaller. But it also adds a lot of complexity and makes the functions non-standard. Removing this might break some of the tinier platforms but it is the best thing to do for long term maintanance for for OpenGroup.org compliance.
Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.
