[ANN] Version 3.0.0-rc1

[Arran Cudbard-Bell]

We are in feature freeze for 3.0. The configuration format and behaviour for 3.0 will be stable between now and the final release (as it was with release_3_0_0_rc0).

If you are planning on deploying 3.0 and have an existing 2.x.x configuration you were planning to migrate when the 3.0 is released, now would be a good time to try that, and to report any issues or problematic behavior changes you notice.

To provide a single point to test against, the release_3_0_0_rc1 tag has been created.

Behaviour changes since release_3_0_0_rc0:
* Fixed many more compiler warnings.
* LDAP schemas to load dynamic clients from LDAP
* the control socket is now marked "stable"
* Added RFC 6929 dictionary, along with a few others
* Clean up proxy ID allocation / re-allocation
* pairbasicfree() has been replaced by talloc_free()
* Added %{debug_attr:LIST} to print out at attributes in LIST
* The PAP module can now configurably *not* normalize passwords
* Remove support for %{#}, and add %{strlen:} expansion 

Bug fixes:
* Corrected more documentation to match the new behavior and config
* Corrected many minor typos and spelling mistakes in documentation
  and config files
* If the installation directory exists, don't re-install files
* add crlDistributionPoints to certificates for Windows phones.
* Use documentation IP addresses everywhere (192.0.2/24)
* Build fixes for clang related to the -rdynamic flag
* Allow "update" sections to update outer.reply
* Re-write module handler to work, the code is significantly cleaner,
and priority overrides work correctly in all cases, #404, #424
* CUI SQL fixes, #412
* Don't die in RB tree re-allocation of proxy ID
* Do a second pass over pre-compiled conditions, #421, #423
* Add "delete order" to rbtree, #416
  Also used by the proxy ID re-allocation code
* Fixed TCP socket close handlers to be simpler and more robust
* Allow ${..} expansion in `strings`
* moved EAP destructors to talloc, which wasn't done in -rc0
* Fix LDAP group comparisons, and other pair comparisons
* NULL terminate strings copied between VALUE_PAIRs correctly
* Fix !* when used with non-string attributes
* Fix `` exec in update sections
* Load libpython within rlm_python to ensure all required symbols are available
* Don't SEGV printing IPv6 Interface ID
* Don't SEGV evaluating dates in rlm_expiration
* Fix ./configure --with-shared-libs=no
* Fix crashes related to opaque request data and regular expressions
* Fix heimdal krb5 build
