[Mono-dev] Add openat() etc. to Mono.Posix

[Steffen Kieß]

Hello,

some time ago I submitted a pull request which adds openat() and some
other methods to Mono.Posix:
https://github.com/mono/mono/pull/221

A related pull request for mono-tools (which is needed for the mono pull
request):
https://github.com/mono/mono-tools/pull/22


Is there anything else I should change in the pull request?


Best regards,
Steffen Kieß
