Don't scan C source code for Lisp symbols.

* eval.c (eval_init): Register package-alist, package-name
and package-symbols intrinsics.

* genvim.txr: Rather than scanning C sources for TXR Lisp
symbols, iterate over the packages and their symbols,
collecting anything which has a binding or is self-evaluating.
To get the stdlib symbols, we trigger the autoloads by doing
boundp queries on a few symbols.

* txr.1: Document package-alist, package-name and
package-symbols.
