If the argument provided to pidfile(3) contains a '/', then the value is
considered to be an absolute/relative path and the pid file is created
in the given location.
Otherwise, pidfile(3) behaves as before and treats the provided value as
a basename to construct a pid file in /var/run/<basename>.pid. This means
that to create a pid file named "foo.pid" in the current directory, one
must specify "./foo.pid".
- Make the pidfile name generation functions return their value as a return
value, not an output pointer. And homogenize these into a single function.
- Free allocated memory. Not truly necessary because the test cases die
immediately anyway, but nice to do.
- Remove the pidfile__ prefix from test case names. (This was in advance of
some changes I want to propose to pidfile(3), but it turns out my approach
was flawed. Preemptive smartness is evil!)
- 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.

XXX the ugly sleep at the end is because ATF will mark an un-triggered
race condition (ie, the test passes unexpectedly) as a test failure otherwise.
