New ecase macros.
Even prior to discovering the recent defect in deffi, which
was caused by a missing case in caseql, combined with poor
testing, I was already thinking about adding ecase macros.
The introduction of must-match and must-match-case also shows
my motivation. That deffi bug convinced me to take action
and implement these.
* eval.c (case_error_s) New symbol variable.
(me_ecase): New static function.
(eval_init): Register new intrinsic macros ecaseq, ecaseql,
ecasequal, ecaseq*, ecaseql* and ecasequal*.
Intern case-error and initialize case_error_s.
* txr.1: Documented. Also updated Exception Hierarchy diagram
with match-error and case-error.
* stdlib/doc-syms.tl: Updated.
