bc: partially rewrite parser, tests pass, ^C might be broken now
...
The entire control construct (if/while/for/funcdef) or {} block is
"eaten" by the corresponding parsing function, instead of maintaining
special "block flag stack" with magic bits in it, and returning to main
input loop after every inner statement (every input line, essentially).
This required moving line input deep into lexer - now zbc_lex_next()
triggers more reading when needed.
"block flag stack" is gone.
Correctness of ^C handling wasn't checked, might need fixing now.
if/else syntax is changed to match GNU bc: "else" can not be on
the next line (the rationale is that "if (1) 2" statement in interactive
mode should execute and print 2 instead of waiting for possible
"else ..." line).
This change fixes the following examples:
if (1) if (1) 1 else 2 else 3
if (0) 1 else if (1) 2
define w() { auto z; return 1; }

Each access to current top flag took a function call + fetch of three data items
+ multiplication and some additions + and then following the resulting pointer.
After the change, it is: fetch pointer value + one byte access via this pointer.
