df8a8b4e9e Revamp command line options to add mcpp mode with defaults. 
Also remove stderr from subprocess call (let the subprocess do its own output to stderr without capturing and re-emitting it ourselves).

b8f73bb5e1 Don't open the script in binary mode, open it in text mode. 
Not too sure about this change, but it eliminates CRs before LFs.

9bd66dd6fa Optimize out function calls to SEF functions with non-SEF arguments. 
The function call is removed, and the arguments transformed to a block of expression statements.

df31a69465 In functions that end in 'return;', remove the 'return;'. 
This allows better side-effect analysis, because 'return' is not side-effect free unless it's the last statement. But that's better handled in the dead code removal module, as the comment specifies.

fc7abc7d99 Fix bug broken by 562154e7aa. 
Referencing a global that was optimized out, caused a crash.

```
integer DEBUG = 1;

default
{
    state_entry()
    {
        if (DEBUG) llOwnerSay("DEBUG");
    }
}

Makes this script work, as it should:

`default { timer() { string llSay; llSay(0, llSay); } }`

890e960b57 Implement Lazy List reading. Update docs according to last changes (in FS too). 
Adds a new tree node type, SUBIDX, which hopefully should never appear in actual output. If it does, it's prefixed with the string (MISSING TYPE) as a cue to the programmer.

9c926b6fec Fix obsolete comment. 
There was a time where I decided that the tree would be stored inside the symbol table, as values for the global symbols. I changed my mind later and separated them, but that comment remained.

6a0eebf157 Implement a couple subtleties of the lexer in the handling of strings. 
First, a string does not have its own context, it's a regular expression, therefore if there isn't a matching closing quote until EOF, it's not an unterminated string. It plainly *isn't* a string.

Second, the string lexer searches for either the regexp '[^"\\]' (any character except a double quote or a backslash) or the regexp '\\.', that is, a backslash followed by an "any character" meta. But the "any character" meta does NOT match a newline. The consequence is that a '\' followed by a newline cancels the matching, and the whole thing is not considered a string.

Isolated double quotes are then plain ignored as many other characters.

An example illustrating both cases:
```
default
{
    state_entry()
    {
        string msg = "Hello, Avatar!";
        llOwnerSay"(msg); // the opening quote will be ignored
        // the following backslash at EOL cancels the previous double quote: \
        llOwnerSay(llGetKey(")); // Unterminated string; unmatched so ignored.
    }
}
```

1e8b77bf50 Rather than generating random identifiers for locals, prefix them with 'loc_'.
