bc: remove "error after expression parsing" check
...
It is misplaced: caller knows better what can or cannot follow the expression.
Sometimes even caller's caller: "if (1) return a+b else..." -
parser of "return" does not know that "else" after it is valid,
parser of stmt does not know it either, - only parser of
"if" knows it!
The removed code balked on e.g. "{ print 1 }" statement.
This does not break any valid programs, but starts accepting some
invalid ones, e.g. "print 1 print 2" would work.

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; }

tar,unzip: postpone creation of symlinks with "suspicious" targets
...
This mostly reverts commit bc9bbeb2b8https://bugs.busybox.net/show_bug.cgi?id=8411
In particular, this interferes with unpacking of busybox-based
filesystems with links like "sbin/applet" -> "../bin/busybox".
The change is made smaller by deleting ARCHIVE_EXTRACT_QUIET flag -
it is unused since 2010, and removing conditionals on it
allows commonalizing some error message codes.
