	* include/dlfcn.h: __libc_dlopen is now a macro calling
	__libc_dlopen_mode with the extra parameter RTLD_LAZY.
	(__libc_dlopen_mode): New prototype.
	* elf/dl-libc.c (__libc_dlopen_mode): Renamed from __libc_dlopen.  Add
	new parameter.  Store new parameter in mode field of structure passed
	to do_dlopen.
	(struct do_dlopen_args): Add new field mode.
	(do_dlopen): Pass mode from parameter structure to _dl_open.

	* sysdeps/unix/sysv/linux/hppa/sys/ucontext.h:
	Define mcontext_t as a sigcontext.
	* manual/crypt.texi (Cryptographic Functions): Mention that
	the MD5 one-way algorithm is compatible with BSD's.
