Motiejus Jakštys 5bd533d40c parser: replace fprintf+longjmp with fail(), add forward declarations

Introduce a fail(p, "msg") inline function that stores the error message
in a buffer and longjmps, replacing ~52 fprintf(stderr,...)+longjmp pairs.
The error message is propagated through Ast.err_msg so callers can decide
whether/how to display it. Also add forward declarations for all static
functions and move PtrModifiers typedef to the type definitions section.

Testing

Quick test:

zig build fmt && zig build

Debugging tips

Test runs infinitely? Build the test program executable:

$ zig build test -Dno-exec

And then run it, capturing the stack trace:

gdb -batch
-ex "python import threading; threading.Timer(1.0, lambda: gdb.post_event(lambda: gdb.execute('interrupt'))).start()"
-ex run
-ex "bt full"
-ex quit
zig-out/bin/test

You are welcome to replace -ex "bt full" with anything other of interest.
