crtend: accurately check for the start of .ctors

For the hypothetic situation where crtbegin.o is not linked into the
binary, but crtend.o is, which results in the missing starting sentinel
in the ctors array, be careful to not iterate past the start of the
section.

Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

Rename __JCR_LIST__ to __JCR_END__ in crtend.c.

This is more consistent with the names used for .ctor and .dtor
symbols and better reflects __JCR_END__'s role.

csu: Fix dynamiclib/init_test:jcr_test on !HAVE_CTORS archs

.jcr still needs a 0-entry added in crtend, even on !HAVE_CTORS archs, as
we're still getting .jcr sections added -- presumably due to the reference
in crtbegin. Without this terminal, the .jcr section (without data) overlaps
with the next section and register_classes in crtbegin will be examining the
wrong item.

Merge ^/head r340869 through r340917.

Add the missing 0 at the end of the .jcr section.

Without this the dynamic library test was failing as it was calling
_Jv_RegisterClasses multiple times.

Merge ^/head r339813 through r340125.

Make the .ctors, .dtors, and .jcr markers as static. They shouldn't be
accessible from out of the files they are defined in.

Implement a BSD licensed crtbegin/crtend

These are needed for .ctors/.dtors and .jcr handling. The former needs
all the function pointers to be called in the correct order from the
.init/.fini section. The latter just needs to call a gcj specific function
if it exists with a pointer to the start of the .jcr section.

This is currently disabled until __dso_handle support is added.
