Re-add libsieve version 2.2.5.

This library was forked from CMS Sieve, it had existed here before.

Changes from fork:

libSieve 2.2.5
--------------

- Allowed CFLAGS to pass through Makefile.am
  (thanks to Bernard Johnson).

- Use # instead of __STRING for assertion stringification.

- Fixed off-by-one when reallocing space for repeated headers
  (thanks to Petri Laine).

libSieve 2.2.4
--------------

- Improved several test scripts.

- Fixed a memory leak in header parsing.

- Fixed a memory leak in comparator lookup.

- Accepted patch from Steffen Schuetz to respect :from in vacation action.

libSieve 2.2.3
--------------

- Numeric relational comparators were backwards.

libSieve 2.2.2
--------------

- Added more test scripts.

- Added support for RFC 3431 Relational comparators.

- Fixed segfault when parsing group syntax with empty address list.

libSieve 2.2.1
--------------

- Removed accidental dependency on Check.

- Added exception handling system.

- Added test runner scripts to sv_test.

libSieve 2.2.0
--------------

- Updated top-level README.

- Fixed address test not working.

- Fixed innocuous yet annoying GCC 4 warnings.

libSieve 2.1.13
---------------

- Fixed capabilities missingspaces.

- Fixed alloca.h in vasnprintf for FreeBSD.

libSieve 2.1.12
---------------

- Fixed namespace issue with vasnprintf.

libSieve 2.1.11
---------------

- Minor fixes to build with flex 2.5.33.

- Updated to Vacation draft 6.

- Updated to imap4flags.

- Dropped support for imapflags.

- Added callback for subaddress rather than
  using a hardcoded user+mailbox format.

- Added a callback for debug messages.

- Regex is always built in now.

- Fixed multiline "text: string ." blocks.

libSieve 2.1.10
--------------

- Fixed sieve2_listextensions.

- Fixed segfault when client returns null
  pointers from the getenvelope callback.

- Improved handling of extension require's.

- Fixed segfault when parsing zero length address.

libSieve 2.1.9
--------------

- Fixed subaddress, getenvelope and vacation.

- Added additional debugging messages.

- Added new and updated draft rfc's.

libSieve 2.1.8
--------------

- Created a testsuite of scripts and messages
  to exercise RFC and Draft comformance.

- Fixed a memory allocation issue that prevented
  the library from being used again after sieve2_free
  had been called.

libSieve 2.1.7
--------------

- Rewrote the API again. I finally like it!

- Settled on the LGPL for all of my new code.

- Replaced the RSA MD5 implementation with
  a public domain version.

- Documentation updated for the new API.

libSieve 2.1.6
--------------

- Added a set of error-retrieval functions.

libSieve 2.1.5
--------------
(formerly libsieve 2.2.0_pre3)

- CFLAGS now includes -Wall and compiles very
  cleanly. Messages from lex/yacc are benign.

- Namespace cleanups: internal global functions
  prefixed with "libsieve_" for consistency.

- Local regex library, borrowed from GNU glibc
  2.3.2. Used under LGPL license version 2.1.

- Compiles under Win32 with Visual C++, with
  many thanks to Brandon Knitter.

libSieve 2.1.4
--------------
(formerly libsieve 2.2.0_pre1)

- Sieve 2 API has begun. More changes should
  be expected during the 2.1 series.

- All later-CMU code removed and/or replaced;
  original licensing is now entirely old-CMU
  style and augmented by the GNU GPL as it is
  placed on all new code and applies to the
  distribution as a whole from here forward.

- "Poor man's parsers" for RFC 2/822 addresses
  and message headers replaced with lex/yacc.

- Extensive Valgrinding performed to identify
  memory leaks; no known leaks remain.

- Many more changes, amounting to perhaps a
  70% rewrite of all code.

libSieve 2.1.3
--------------

- Accepted patches from Timo Sirainen:

  - Added function xstrconcat
  - Changed strdup to strndup
  - Changed strcpy to xstrcpy
  - Changed uglies to xstrconcat
  - Rebuild .y and .l in Makefile.am
  - Changed int to size_t where applicable
  - Added explicit casting where applicable

- Accepted patches from Oliver Tappe:

  - Fixed examples for the web site
  - Removed useless headers
  - Now builds on BeOS

- Cleaned up lots of K&R style function declarations

libSieve 2.1.2
--------------

- Changed `timestamp` to $timestamp in configure scripts.

- Added missing autoconf and libtool scripts.

- Fixed a typo in index.html

libSieve 2.1.1
--------------

- First public release of the libSieve distribution.

- com_err library removed.

- Conversion to GNU autotools for the build process.

libSieve 2.1.0
--------------

- Forked from CMU Sieve 2.1.

- SourceForge project site and a new web site and CVS tree and prepared.

- Dependencies on libCyrus trimmed to a bare minimum.

+This code is a standalone library providing an interpreter for RFC 3028 Sieve
+and various extensions. It is based upon code distributed with the Cyrus Mail
+Server prior to CMU's switch to a more restrictive license. The libSieve API
+attempts to be easy to use and extensible, and replaces the more rigid API in
+the Cyrus Sieve implementation.
