Move bfd_init to bfd.c

init.c contains just one function that doesn't do much.  Move it to
bfd.c and give it something to do, initialising static state.  So far
the only initialisation is for bfd.c static variables.

The idea behind reinitialising state is to see whether some set of
flaky oss-fuzz crashes go away.  oss-fuzz stresses binutils in ways
that can't occur in reality, feeding multiple testcases into the
internals of binutils.  So one testcase may affect the result of the
next testcase.

	* init.c: Delete file.  Move bfd_init to..
	* bfd.c (bfd_init): ..here.  Init static variables.
	* Makefile.am (BFD32_LIBS): Remove init.lo.
	(BFD32_LIBS_CFILES, BFD_H_FILES): Remove init.c.
	* doc/local.mk: Remove mention of init.texi and init.c.
	* Makefile.in: Regenerate.
	* bfd-in2.h: Regenerate.
	* po/SRC-POTFILES.in: Regenerate.
