- Support for i18n in libNX_X11 is static only, has ever been.
 - Thus, the files XlcSL.[co], XlcDL.[co], XDefaultIMIF.[co],
   XDefaultOMIF.[co] and lcDynamic.[co] become obsolete.

doc/libNX_X11/lcUniConv: Move over the rather-documentary files 8bit_tab_to_h.c and cjk_tab_to_h.c to nx-libs's doc/ folder.

Creating libX11 symlinks breaks our builds in clean environments. Drop this
feature for now.

It must be rewritten to only create the symlinks after everything has been
built.

is_numeric is only needed if X11_t is defined.

Silences "warning: ‘is_numeric’ defined but not used [-Wunused-function]"

warning: "XTRANS_SEND_FDS" is not defined [-Wundef]

This define came in via the recent xtrans update.

warning: format ‘%p’ expects argument of type ‘void *’

This lifts xtrans to the state of this commit:

"""

It's simply obsolete, sloppy, compiler namespace pollution.  The
compiler is not allowed to predefine symbols that might conflict with
ordinary identifiers.  For backwards compatibility gcc currently
predefines i386 when compiling for x86 32-bit (but not 64-bit), but that
will go away.  It is also not defined if you specify -ansi when invoking
the compiler, because then it is seriously standards compliant.  Other
compilers shouldn't define it either.  Correct code shouldn't rely on it
being defined.  However __i386__ is safe and proper.
