ast_copy_string is not available when LOW_MEMORY is used and things are being built in the utils directory, so we need to resort to the old method of strncpy. (issue #8579 reported by mottano)

Jason is having problems with the inclusion of <err.h>; it appears to be unnecessary for sucessful builds, so I either removed or commented out the inclusions from all the AEL related code. New outputs from bison/flex are included, etc.

 ; If you have data which may potentially contain single ticks, you may wish
 ; to use the dialplan function SQL_ESC() to escape the data prior to its
 ; inclusion in the SQL statement.
+;
+;
+; The following variables are available in this configuration file:
+;
+; readhandle   A comma-separated list of DSNs (from res_odbc.conf) to use when
+;              executing the readsql statement.  Each DSN is tried, in
+;              succession, until the statement succeeds.  You may specify up to
+;              5 DSNs per function class.  If not specified, it will default to
+;              the value of writehandle or dsn, if specified.
+; writehandle  A comma-separated list of DSNs (from res_odbc.conf) to use when
+;              executing the writesql statement.  The same rules apply as to
+;              readhandle.  "dsn" is a synonym for "writehandle".
+; readsql      The statement to execute when reading from the function class.
+; writesql     The statement to execute when writing to the function class.
+; prefix       Normally, all function classes are prefixed with "ODBC" to keep
+;              them uniquely named.  You may choose to change this prefix, which
+;              may be useful to segregate a collection of certain function
+;              classes from others.
+; escapecommas This option may be used to turn off the default behavior of
+;              escaping commas which occur within a field.  If commas are
+;              escaped (the default behavior), then fields containing commas
+;              will be treated as a single value when assigning to ARRAY() or
+;              HASH().  If commas are not escaped, then values will be separated
+;              at the comma within fields.  Please note that turning this option
+;              off is incompatible with the functionality of HASH().
