move some functions from exported header <openssl/dtl1.h> into "ssl_locl.h";
fix silly indentation (a TAB is *not* always 4 spaces)

PR: 959

resolved by recent commits.

(Also remove another "make update".)

branch (OpenSSL_0_9_7-stable) that do not appear similarly in
0.9.8-dev (CVS head).

Some obvious false positives have been eliminated: e.g., we do not
care about a simple "make update"; and we don't care about changes
identified to the 0.9.7 branch that were explicitly identified as
backports from head.

Eliminating all other entries (and finally this file), either as false
positives or as things that should go into 0.9.8, remains to be done.

Update dependencies.
