Move USE_BDB support from bsd.databases.mk to its own file.

Also:
- Deorbit WANT_BDB_VER, one can use USES=bdb:<ver> instead.
- USE_BDB can't happen after bsd.port.pre.mk because it is a USES.

+# Provide support for Berkeley DB
+# Feature:	bdb
+# Usage:	USES=	bdb[:version]
+#
+#			  If no version is given (by the maintainer via the port or
+#			  by the user via defined variable), try to find the
+#			  currently installed version.  Fall back to default if
+#			  necessary (db5 if compatible).
+#			  This adds a "debug-bdb" make target which will dump the
+#			  related data.
+# INVALID_BDB_VER
+#			- This variable can be defined when the port does not
+#			  support one or more versions of Berkeley DB.
+# WITH_BDB_VER
+#			- User defined global variable to set Berkeley DB version.
+# <BDB_UNIQUENAME>_WITH_BDB_VER
+#			- User defined port specific variable to set Berkeley DB
+#			  version.
+# WITH_BDB_HIGHEST
+#			- Use the highest installed version of Berkeley DB.
+# WITH_BDB6_PERMITTED
+# 			- If defined, BerkeleyDB 6 is added to the
+# 			  default version set, making it eligible even
+# 			  if not already installed. This is due to its
+# 			  stricter Affero GNU Public License.
+#
+# These variables will then be filled in by this .mk file:
+#
+# BDB_LIB_NAME
+#			- This variable is automatically set to the name of the
+#			  Berkeley DB library (default: db41).
+# BDB_LIB_CXX_NAME
+#			- This variable is automatically set to the name of the
+#			  Berkeley DB C++ library (default: db41_cxx).
+# BDB_INCLUDE_DIR
+#			- This variable is automatically set to the location of
+#			  the Berkeley DB include directory (default:
+#			  ${LOCALBASE}/include/db41).
+# BDB_LIB_DIR
+#			- This variable is automatically set to the location of
+#			  the Berkeley DB library directory.
+# BDB_VER
+#			- Detected Berkeley DB version.
