On the svn-auth-x509 branch: Ise apr_size_t instead of int to store
ASN.1 and DER buffer lenghts. This incidentally fixes a compiler warning
in subversion/svn/auth-cmd.c.

* subversion/include/svn_x509.h
  (svn_x509_parse_cert): Change parameter buflen to apr_size_t.
* subversion/libsvn_subr/x509.h
  (_x509_buf): Change the len field to apr_size_t.
* subversion/libsvn_subr/x509parse.c
  (asn1_get_len, asn1_get_tag): Change parameter *len to apr_size_t.
   Update all callers.
  (svn_x509_parse_cert): Implement the prototype change.
