consolidated into the Operation structure. All reply parameters
are consolidated into the new SlapReply structure. Most operations
now have identical call signatures... Changes are not #ifdef'd,
revert to -r NO_SLAP_OP_BLOCKS if necessary to back out.

It has just occurred to me - duh - that the process ID of a back-shell
command is a perfectly good unique ID for it, and more useful than
any connection id/message id thingy. Doesn't need extra arguments
to the shell commands either, except a pid: line to abandon.
And msgid: can still be removed in a future version.
Here is a patch.

A surrogate parent is supposed to keep back-shell children from
deadlocking due to resources locked by a threading parent.
Implementation note: The surrogate parent closes all unused file
descriptors, so it logs errors to stderr instead of via Debug() and
uses relloc() instead of ch_realloc().
Also close a file descriptor leak if fork() fails in fork.c.

Here is a patch which does what I described. Of course, someone has
to decide if that is the right solution:-)
- Add an "opid:" line to the input to back-shell commands.
- Add an "abandonid: <opid> line to back-shell/abandon input.
- Replace message id with opid in back-tcl arguments.
- Add an abandonid = <opid> argument to back-tcl/abandon.
An opid (operation ID) is a "connection ID/message ID" string. I
would have liked to use another name to avoid confusion with struct
slap_op->o_opid, but I could not think of another apt word.
This also fixes ITS#1784 and ITS#1792. Since calling conventions
changed anyway, I fixed back-shell by adding abandonid: and making
opid: always be the ID of the current operation.

Includes support for update referral for each replicated backend.
Reworked replication test to use update referral.
Includes major rewrite of response encoding codes (result.c).
Includes reworked alias support and eliminates old suffix alias codes
(can be emulated using named alias).
Includes (untested) support for the Manage DSA IT control.
Works in LDAPv2 world. Still testing in LDAPv3 world.
Added default referral (test009) test.
Separates per backend type from per backend database initialization
and startup. Also supports per type / per backend shutdown.
New frontend startup/shutdown routines are also provided:
slap_init() slap_startup() slap_shutdown() slap_destroy()
New frontend->backend startup/shutdown is managed by:
backend_init() backend_startup() backend_shutdown backend_destroy
backend_init() now calls bi_init() to initial all function pointers
for the backend (excepting bi_init() which is now the only hardcoded
entry point). New entry points are detailed in slap.h struct
backend_info. backend_info is a per database type structure.
Besides the new startup/shutdown entry points, the new interface
also supports per backend type configuration options. One could have:
backend bdb2 (new Berkeley DB 2 backend)
bdb2_home /directory
database bdb2
...
*** This code is fairly experimental ***
*** Much cleanup and testing is still needed ***
see slap.h for details on struct backend_db and backend_info.
Most function and variable definitions are now preceded by its extern
definition, for error checking. Retyped a number of functions, usually
to return void. Fixed a number of printf format errors.
API changes (in ldap/include):
Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.
A number of `extern' declarations are left (some added by protoize), to
be cleaned away later. Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.
