environment handling fixes
* AC_CHECK_FUNCS: +setenv +unsetenv -putenv
(the check for putenv() wasn't used anyway)
* prefer setenv() to putenv() in cmd_setenv()
* prefer unsetenv() to putenv() in cmd_unsetenv()
- putenv("FOO") isn't legit everywhere
- putenv("FOO=") will only work on MinGW
* make the getenv command return an empty output if the variable wasn't found
* while here, split and sort AC_CHECK_FUNCS
|cos| on #ratpoison reported that environment variables weren't
properly removed, and proposed a different fix. thanks!
