Big changeset that includes the work around keytab management.

Following the changelog history from my dev tree, some comments are useful imo

description:
transform the old ipa-getkeytab in a tool to add services as the new
ipa-getkeytab won't do it (and IMO it makes more sense to keep the
two functions separate anyway).

Messed a bit with hg commands.
To make it short:
- Remove the python ipa-getkeytab program
- Rename the keytab plugin test program to ipa-getkeytab
- Put the program in ipa-client as it should be distributed with the client
  tools

description:
If ber_peek_tag() returns LBER_ERROR it may just be that we are at the
end of the buffer. Unfortunately ber_scanf is broken in the sense that
it doesn't actually really consider sequence endings (due probably to the fact
they are just representation and do not reflect in the underlieing DER
encoding.)
