remove linuxthreads.new, rename linuxthreads.old

Linuxthreads.new isn't really useful with the existence
of NPTL/TLS for well supported architectures. There is no
reason to use LT.new for ARM/MIPS or other architectures
supporting NPTL/TLS. It is not available for noMMU architectures
like Blackfin or FR-V. To simplify the live of the few uClibc-ng
developers, LT.new is removed and LT.old is renamed to LT.

-vda: here is why:
-headers contain libc_hidden_proto(foo).
-In libpthread/linuxthreads.old/sysdeps/pthread/bits/libc-lock.h
-adding libc_hidden_proto(foo) just before weak_extern (__pthread_initialize)
-will not warn:
-    /* libc_hidden_proto(foo) */
-    weak_extern (__pthread_initialize)
-    /* libc_hidden_proto(foo) */
-but adding after will! Which is extremely strange -
-weak_extern expands into just "#pragma weak __pthread_initialize".
-TODO: determine whether it is a gcc bug or what
-(see gcc.gnu.org/PR36282).
-For now, just include all headers before internals.h
-(they are again included in internals.h - maybe remove them there later)
