add support for program_invocation[_short]_name this is a bit ugly, and the motivation for supporting it is questionable. however the main factors were: 1. it will be useful to have this for certain internal purposes anyway -- things like syslog. 2. applications can just save argv[0] in main, but it's hard to fix non-portable library code that's depending on being able to get the invocation name without the main application's help.

use __attribute__((const)) for errno and pthread_self if __GNUC__ is defined this is not too ugly and should result in significant code size and performance improvements for many programs.
