Comment:

 Thanks!  QUick review:

 IMO it's okay to remove id_to_fp.c in 0.2.5 if it's not even compiled.

 The "return -1" cases need to free the buffer if the buffer is non-NULL.

 In addition to the 8 calls to i2d_RSAPublicKey, there are 2 calls to
 i2d_DHParams, 2 calls to i2d_X509, and 4 calls to i2d_PublicKey. Probably,
 they could be simplified as well.
