Starting with #201, source files relative to `_StartDir$` are allowed to
be passed to `-x` and compile as expected. Additionally as part of that
change, when the `-x` parameter is relative to `_StartDir$`, the `-o`
argument is _also_ treated relative to `_StartDir$`. This is simply the
behavior everyone using the compiler would expect - that the source file
and `-o` are relative to the same location.
An overlooked behavior was the executable location when `-o` is not
provided. It still writes to compiler directory, but it really should be
writing to `_Startdir$` since the output executable is intended to be
relative to the same location the source file is relative too. Overall
this is fairly straight forward to fix as the logic is the same, we just
need to make use of it when the `-o` flag is not provided.
Fixes: #257
Some commands like NoPrefix trigger a complete "recompile" due to how
they work. This has the accidental effect of duplicating the command
line output, which should still only be printed once. Moving the
printing logic up a bit is a simple solution.
Fixes: #256
Fairly straight forward, QB64-PE's dependency list has to be built into
the Makefile for when we're building straight from ./internal/source.
Recently it gained a HTTP dependency, so that now needs to be included.

This should fix the comparisons with $IF and VERSION. A few things of note here, which might affect future version labeling:
This expects to find version numbers which follow our current style -- ##.##.## -- 3 numbers, separated by periods.
Adding in alphabetic characters will basically get ignored, and versions with less than 3 values will generate FALSE results in all comparisons.
The current GLUT initialization logic is flawed because it allows the
QB64 code portion of the program to start on a separate thread at the
same time that the GLUT code is starting. This results in a race where
some commands won't work for a brief period at the beginning of the
program (with "won't work" being very inconsistent, some return invalid
values, some have a chance at seg faulting).
The same issue also leads to us adding many `while (!window_exists)`
checks in an attempt to solve this race for some of the commands.
Unfortunately this solution is very inconsistently applied leading to
some deadlock situations, and really it's a silly solution when this
race is entirely our creation anyway.
To fix this, the logic was changed such that we perform all of the GLUT
initialization besides calling `glutMainLoop()` before we ever start the
thread that runs the actual QB64 code. By doing it this way we ensure
that the GLUT initialization has already taken place before the code
runs and thus the race is gone.
Things get a bit more interesting with $SCREENHIDE, because that simply
delays the execution of the GLUT initialization indefinitely until
_ScreenShow is done. This was previously very buggy since some commands
rely on FreeGLUT being up and will simply hang the entire program if
run. Other commands have logic to catch this and simply return zero.
The above issue is solved with the `NEEDS_GLUT()` and `OPTIONAL_GLUT()`
macros. Both of them simply check if the GLUT initialization has taken
place and exit the current function if it has not. The difference
between the two is that `NEEDS_GLUT()` throws an 'illegal function call'
error while `OPTIONAL_GLUT()` simply exits with no error. The choice of
behavior of each function was based upon its previous behavior - if it
checked `screen_hide` and exited with no error previously, then
`OPTIONAL_GLUT()` was used. If it deadlocked or similar then
`NEEDS_GLUT()` was used (so instead of deadlocking, it now produces an
error). In this way, programs can now never get stuck due to the use of
`$SCREENHIDE` and all the commands have consistent behavior that can be
relied upon.
Fixes: #234
Fonts 9, 15, and 17 can *only* be used in SCREEN 0. Attempting to use them in graphic screens results in a seg fault and an instant program crash on Windows. This is definitely the most undesirable of behaviors for a program, and can easily be caught and dealt with just by tossing a simple "Illegal Function Call" error for the issue.
Registering a warning function keeps FreeGLUT from writing warnings to
the console (which is not desirable since it conflicts with our own
console output).
This effectively adds Http support to QB64-PE via adding $Unstable:Http
which will trigger building with DEP_HTTP, which enables Http support in
libqb.
