Avoids redundant files.
And update various notices

Do not use test -a/-o.  Use shell features like &&, || or case...esac.
Use grep instead of egrep (but not the not-yet-portable Posix variant grep -E).
Based on a patch from Paul Eggert.

OpenLDAP 2.x is supported.

and ldap_next_attribute if using newer interface.  Current test for this
is an #if LDAP_API_VERSION >= 2004.

- Detects OpenLDAP 2.0 and builds correctly with it.
- Increment major version to 2, library file to libldaptcl2.0.so.
- Can now perform add/delete/replace modifications in a single command.
- Replaced calls to TclX_WrongArgs with core Tcl_WrongNumArgs to reduce
  dependency on Extended Tcl.
- Wrap dereference search control with #ifdef LDAP_OPT_DEREF.
- Deref during search should work.
- Add protocol_version option to ldap init command.
- Add LDAPTCL_PROTOCOL_VERSION_DEFAULT to allow specifying the default
  protocol version used.
- Add controlArray(timeout) to control timeouts during searches.
- Add controlArray(cache) to control caching current search results.
  (Experience has show this to be not very useful or not working correctly.
  Caching search results should probably be done in Ldaptcl rather than
  letting the LDAP API do it.)
- Add "compare" subcommand
- Add experimental trap subcommand (undocumented -- use at your own risk).

caused incorrect data in result array and possibly segmentation
violations when searches terminated due to errors such as timeout,
exceeding search limit, or the remote server going down in the middle
of a search.  Also correctly puts error message on top of
traceback stack (instead of randomly in memory per the stale result obj).

A segmentation violation could have manifested later in the program's
life, or perhaps during termination of the interpreter.

trap code.

in searches, and experimental "trap" subcommand.

Update single debug/release not to use service manager nor event manager.
Likely breaks MINGW32 port.

Known bug: cache enabled is known to cause Tcl to abort upon exit.

* all others: Added DESTDIR support
