We spare rewind(3)'s sentence because espie@ pointed out that it's a
warning - the function masks a potential error.
This commit also adds a sentence to X509_free clarifying that it's

There is long-standing consensus that err(1, NULL) is the best idiom
after failure of malloc(3) and friends.

The 'A' option elevated warnings to errors, and has been the default for some
time. Then warnings were effectively eliminated in favor of everything
being an error, but then the 'a' flag turned real errors into warnings!
Remove the 'a' option entirely. You shouldn't have used it anyway.

This is slightly less robust, but RAND_MAX must be one below a power
of two in both variants anyway.
Based on a suggestion by Matthew Martin.

1. Optionally add random "canaries" to the end of an allocation. This
requires increasing the internal size of the allocation slightly, which
probably results in a large effective increase with current power of two
sizing. Therefore, this option is only enabled via 'C'.
2. When writing junk (0xdf) to freed chunks (current default behavior),
check that the junk is still intact when finally freeing the delayed chunk
to catch some potential use after free. This should be pretty cheap so
there's no option to control it separately.

stubs for the executable from crtbegin.o into libc, which lets them be
excluded from static links that don't use them.
For this, drop the normal crt{begin,end}S.o from libc.so: the .init and .fini
sections for libc aren't called at the right times anyway, so it's good that
they're unused.  libc.so just needs __guard_local and the .note.openbsd.ident
section, so add them to stack_protector.c for now (this will be improved)

This provides consistent handling of SIGTHR between single- and multi-threaded
programs and is a step in the merge of all the libpthread overloads, providing
some ASM and Makefile bits that the other wrappers will need.
