Change semantics of the errorexit variable.

The "errorexit" variable is a string variable with the same syntax
as errormask.  If a GDBM error is reported and the corresponding
gdbm_errno value is listed in this variable, further script execution
is aborted.

Setting it as boolean value is equivalent to set errorexit="all".

* src/gdbmshell.c (all handlers): Return a GDBMSHELL_* error
code.
(closedb): Unset the fd variable only after closing the database.
(run_command): If handler reported GDBM error and gdbm_errno is
listed in the errorexit variable, return 1 (which will cause YYABORT
in parser).
* src/gdbmtool.h (VAR_ERR_GDBM): New variable error code.
(variable_has_errno): New function.
(gdbm_error_is_masked): Rewrite using variable_has_errno.
* src/gram.y: Abort if run_command or run_last_command return
!0.
Handle VAR_ERR_GDBM.
* src/var.c (variable): New member: data.
(errorexit variable): Change type to VART_STRING; install sethook and
typeconv.
(variable_unset): When unsetting string variable, free and reset its
value.
(cachesize_sethook,centfree_sethook)
(coalesce_sethook): Return VAR_ERR_GDBM on gdbmshell_setopt error.
(errormask_sethook): Keep the mask vector in the data member.
Handle conversions from boolean.
(errorexit_sethook): Call errormask_sethook unless in interactive
session.
