getppid() on win32 (but only Win2k or later).
* process.c (get_ppid): remove win32 special logic.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@17553 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
because there is no path to set it on win32. this patch is derived
from [ruby-core:16787], submitted by Luis Lavena <luislavena at
gmail.com>

* process.c (save_redirect_fd, save_env_i, save_env, run_exec_dup2,
run_exec_open, run_exec_pgroup, run_exec_rlimit, rb_run_exec_options):
save parent's process environments.
!!!remark!!! these are not thread-safe.
* process.c (rb_spawn_internal): remove calling run_exec_options()
because cannot restore after spawn. we'll fix this later.
* io.c (pipe_open): ditto.
* test/ruby/test_process.rb (test_execopts_env): upcase environment
variable name for case insensitive platforms.
* win32/win32.c (init_env): set USER environment variable only when
USERNAME is available.

thread_cleanup_func not to touch pthread data.
pthread_cond_destroy in forked process may cause deadlock on
Debian GNU/Linux Etch on x86, x86-64 and IA64.
this doesn't cause resource leak because the process will exec soon.
