Move bfd_elf_bfd_from_remote_memory to opncls.c

bfd_elf_bfd_from_remote_memory is just a wrapper, and the function
could be implemented for other formats.  Move it to opncls.c because
it acts a little like some of the other bfd_open* routines.  Also give
it the usual FUNCTION etc. comment so prototypes and docs are handled
automatically.

	* elf.c (bfd_elf_bfd_from_remote_memory): Move to..
	* opncls.c: ..here, add FUNCTION comment.
	* bfd-in.h (bfd_elf_bfd_from_remote_memory): Delete prototype.
	* bfd-in2.h: Regenerate.

+DESCRIPTION
+	Create a new BFD as if by bfd_openr.  Rather than opening a
+	file, reconstruct an ELF file by reading the segments out of
+	remote memory based on the ELF file header at EHDR_VMA and the
+	ELF program headers it points to.  If non-zero, SIZE is the
+	known extent of the object.  If not null, *LOADBASEP is filled
+	in with the difference between the VMAs from which the
+	segments were read, and the VMAs the file headers (and hence
+	BFD's idea of each section's VMA) put them at.
+
+	The function TARGET_READ_MEMORY is called to copy LEN bytes
+	from the remote memory at target address VMA into the local
+	buffer at MYADDR; it should return zero on success or an
+	errno code on failure.  TEMPL must be a BFD for an ELF
+	target with the word size and byte order found in the remote
+	memory.
