* common/openpgp-oid.c (openpgp_oid_to_str): Fix unsigned underflow.
* common/t-openpgp-oid.c (BADOID): New.
(test_openpgp_oid_to_str): Add test cases.

The code has an obvious error by not considering invalid encoding for
arc-2. A first byte of 0x80 can be used to make a value of less then
80 and we then subtract 80 from that value as required by the OID
encoding rules. Due to the unsigned integer this results in a pretty
long value which won't fit anymore into the allocated buffer.
The fix is obvious. Also added a few simple test cases. Note that we
keep on using sprintf instead of snprintf because managing the
remaining length of the buffer would probably be more error prone than
assuring that the buffer is large enough. Getting rid of sprintf
altogether by using direct conversion along with membuf_t like code
might be possible.

Be warned that this code is subject to further changes and that the
format will very likely change before a release. There are also known
bugs and missing code.

This is needed so that the agent will be able to export and import
OpenPGP secret keys. Add test case.
Removed unused function.
