Prep .c files for removing the #includes from */archdep.h * replace #include "archdep.h" with #includes of what is used, pulling in "syscall.h", "util.h", and "archdep.h" as needed * delete #include <sys/syscall.h> from syscall.h * only pull in <sys/stat.h> to the three files that use _dl_fstat(), forward declare struct stat in syscall.h for the others * NBBY is for <sys/select.h> macros; just use '8' in dl_printf.c * <machine/vmparam.h> is only needed on i386; conditionalize it * stop using __LDPGSZ: use _MAX_PAGE_SHIFT (already used by malloc.c) where necessary * delete other bogus #includes, order legit per style: <sys/*> then <*/*>, then <*>, then "*" dir.c improvement from jsg@ ok and testing assistance deraadt@

Fix a nasty mem leak in ld.so's own malloc. This was hard to diagnose, since malloc dumping and gdb do not help at all when studying ld.so. In the end it turns out ot be a simple merge error causing extra mmap calls. ok miller@ tb@

Delay processing of ld.so's own PT_GNU_RELRO section until after environment processing and malloc initialization, and then move variables set by those steps, including malloc's mopts structure, into the .data.rel.ro segment. This protects more data and eliminates the extra padding of the mopts. ok kettenis@

Redo the calculation of the alignment and placement of static TLS data to correctly take into account the segment p_align.
