v0.6: "esp= support"
 Changes from v0.5:
	* KLIPS: _no_changes_
	* PLUTO: esp= configurabilty
	- added enum_search() to constants.c: returns value if strcmp()==0
	  Used by parsing logic tricks to allow searching in enum_names
	  arrays (thus avoiding yetanother duplication), eg:         
	  	"3des"  -> "ESP_3DES"
		"md5"   -> "AUTH_ALGORITHM_HMAC_MD5"
	- added "esp" parsing to utils/auto, default=3des
        - added msg.esp (string 7) to whack->pluto protocol 
	- new file alg_info.c for esp algo parsing logic
	  . build proposals with esp= ordered list only _ANDed_
	    with registered (runtime kernel) ESP algos
	  Eg: (assuming all these algos are loaded) in ipsec.conf
	    connection section:
	     <none> or esp=	# default: 3DES+{MD5,SHA1}
	     esp=3des-sha1	# only this: 3DES+SHA1
	     esp=aes,cast	# AES+{MD5,SHA1}, CAST+{MD5,SHA1}
	- alg_info_test: test utility for esp algo parsing, eg:
	      $ cd pluto
	      $ make alg_info_test    
	      $ ./alg_info_test  aes,cast,3des-sha1
		(12 = "ESP_AES", 1 = "AUTH_ALGORITHM_HMAC_MD5")
		(12 = "ESP_AES", 2 = "AUTH_ALGORITHM_HMAC_SHA1")
		(6 = "ESP_CAST", 1 = "AUTH_ALGORITHM_HMAC_MD5")
		(6 = "ESP_CAST", 2 = "AUTH_ALGORITHM_HMAC_SHA1")
		(3 = "ESP_3DES", 2 = "AUTH_ALGORITHM_HMAC_SHA1")

v0.5: "kidnapped CPU hero"
 Changes from v0.4:
  NOTE: you must _really_ clean the build area (*.o ) because some _MAX
        values have changed.

	* KLIPS
	- Changed SADB_EALG_MAX from 12 to 256 (to accomodate ESP enc ids
	  like ESP_SERPENT=252, ESP_TWOFISH=253)
	- Added timing measurement tests (cipher "bandwidth"), eg:
	   # modprobe ipsec_twofish test=1
	   # dmesg | tail -9
	   ipsec_twofish_init(enc_alg=253 name=twofish): ret=0
	   klips_debug:ipsec_ext_test: enc_alg=253 blocksize=16 \
	   		key_e_size=8892 keysize=16
	   klips_debug:ipsec_ext_test: cbc_encrypt=1 ret=1024
	   klips_debug:ipsec_ext_test: memcmp(enc, tmp) ret=1: OK.
	   klips_debug:ipsec_ext_test: cbc_encrypt=0 ret=1024
	   klips_debug:ipsec_ext_test: memcmp(dec,tmp) ret=0: OK.
	   klips_debug:ipsec_ext_test: decrypt speed=25200 KB/s
	   klips_debug:ipsec_ext_test: encrypt speed=28600 KB/s
	   ipsec_twofish_init(enc_alg=253): test_ret=0

	- Changed BLOWFISH to use asm versions if possible
	- Added SERPENT, TWOFISH from
		Dr Brian Gladman http://fp.gladman.plus.com/index.html
		(nicely hacked to un-global-ize sources)
	- Added CAST from 
		OpenBSD sources ("public domain")
		*tested Ok against OpenBSD 3.0*
	- Added NULL from
		me :)

	* PLUTO
	- (also touched by SADB_EALG_MAX changes) please _really_ clean
	  lib/*.o pluto/*.o before recompiling
	- esp_transform_name bumped to 256 entries (from about 12)
	- first attr.key_len processing (be careful, may break)
	  no negotiation, just use peers attr.key_len  if it's lower
	  than maxkeybits
	- patch from Nigel Metheringham to allow RH62/2.2.20 compilation

v0.4: 
	First release (should fill-in here :)
