- no need for all the weak symbols
- define a new _VIS_END flag for UNVIS_END so that there are no collisions
between and vis and unvis flags.
- add bound versions of the vis and unvis functions that take the length of
the destination buffer. Unlike the OpenBSD ones they return -1 or NULL if
the buffer is not large enough, instead of silently truncating.
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.
Fixes floating point exceptions in _longjmp() during /etc/rc and
now NWS-3470D boots up to multi user with -current userland binaries.
Also fill BDslots in error path properly.
Rename __libc_init to _libc_init and call it explicitly from CSU code.
This enforces the constructor run order for newly linked programs.
Keep it as constructor with run-once semantic for binary compatibility.
Implement dl_iterate_phdr for statically linked programs.

to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

(to do long double), we need to not only handle the hardware exception
mask and cummulated flags, but also update/query the softfloat variables.
Since this may go away sometime (to make us psABI compliant), ifdef it
properly.
