Complete the ld.so boot cleanup: move most libc initialization from
_csu_finish() to _libc_preinit(), which is an .init_array function
in shared libc (and mark it INITFIRST) or a .preinit_array function
in static libc, grabbing the _dl_cb callback there from ld.so. Then
in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's
startup bits before main() gets control.

Other cleanups this permits:
- move various startup structures into .data.rel.ro
- the dl* stubs in libc can be strong and call the callbacks provided
via _dl_cb
- no longer need to conditionalize dlctl() calls on presence of _DYNAMIC

Enable LIBREBUILD to construct libc.so.*.a

libc.so can't be unloaded, so move the hidden atexit() and pthread_atfork()
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)

The only thing that was translated into multiple languages in OpenBSD
are the errno messages and signal names. Everything else is in
English. We are not planning to translate more text. Running a
mixed system with less than 1% of the text in native language makes
no sense. So remove the NLS support from libc messages. The
catopen(3) functions stay as they are.

Nuke the machinery to sync libkern with libc, it's not been used in the

From Jean-Philippe Ouellet

warn about implicit. misspelled function names in libc are deadly.

Fix catopen(3) for UTF-8 locales and update the implementation to POSIX-2008.

Catalogs had an arbitrary character set which was used regardless of locale.
Add UTF-8-encoded catalogs for libc error messages, and rename existing ones
to indicate their character sets. catopen(3) now chooses a catalog which
matches the locale's encoding, if available.

A couple small but long anticipated changes:

- Link libpthread.so with -znodlopen. Because libpthread overrides
the weak symbols in libc, we can't allow it to be dynamically
loaded or else libc's weak symbols might have already been
resolved by ld.so. (Also, major bump because this is technically
a backwards incompat change in behavior, although dlopen()ing
libpthread never really worked.)

- Link libc.so with -nodefaultlibs -lgcc. This ensures that libc
doesn't try to link against itself (which ld.so wouldn't like).

- Change GCC 4 to link shared objects with -lpthread and -lc as
appropriate, now that there's no issues with doing so. This means
that it's no longer necessary to patch software to use -pthread
instead of -lpthread. (Ports tree rejoice!)

Also, to preemptively answer this question: No, this does not
eliminate the need for LD_PRELOAD=libpthread.so. That's a separate
issue that won't be resolved until we eliminate libc's weak symbols.

Discussed extensively on email and icb over the past few months.
