initialize ex_pathlen to -1 so it isn't checked if pathlen
is not present.

set ucert to NULL in apps/pkcs12.c otherwise it gets freed
twice.

remove extraneous '\r' in MIME encoder.

Allow a NULL to be passed to X509_gmtime_adj()

Make PKCS#7 code use definite length encoding rather then
the indefinite stuff it used previously.

  Changes between 0.9.5a and 0.9.6  [xx XXX 2000]
 
+  *) Modification to PKCS#7 encoding routines to output definite
+     length encoding. Since currently the whole structures are in
+     memory there's not real point in using indefinite length 
+     constructed encoding. However if OpenSSL is compiled with
+     the flag PKCS7_INDEFINITE_ENCODING the old form is used.
+     [Steve Henson]
+
   *) Added BIO_vprintf() and BIO_vsnprintf().
