XSB Src (SVN)-old

updates to the curl package and the related part in standard.P
Fixes the problem of posting to a URL.

Updated tests so that they no longer use use_incremental_tabling or
use_opaque_tabling. Expanded directives and declarations test and
added test of tabled dynamic code.

Refactored and expanded code for dynamic/1 and table/1, and made
code for declarations and directives mre similar. I fixed a bug
with dynamic pred as tabled, rewrote some obscure code to fix a
memory leak in double allocation of prrefs, and fixed a bug to
allow static code to be rewritten as nonincremental or as opaque.
Also, I added inconsistency checks for dynamic and tabled
options.

Forgot to add these.

Changed multifile in load_dyn to use whole filename as modifier,
rather than just the "module" name. Then can use same file name in different
directories.

Changes to allow directives to change between incremental , nonincremental, and opaque.

biassert.c -- minor doc change

Others: changes to allow directives to change tables among
incremental, nonincremental, and opaque.

Added a test of various kinds of tabling and dynamic directives.

Expanded to test of error-checking.
