handle inline c-like comments in lexer

Report only one error when invalid shift has argument

Not *necessary*, but if you don't know better, you should probably use it.
Fixes rgbds-www#9

Don't overwrite symbol when it's not allowed

Don't consider difference of invalid labels constant

If a label is defined outside of a section, avoid trying to obtain its
value.

Not to mention that incrementing a variable in a loop is kinda dumb.

When a user tried to overwrite a builtin symbol, it would change its
type despite the error, mak...

reserveSpace: don't assume one doubling is enough

utf8decoder: Use byte-sized byte argument

Gets rid of `open_memstream`, enabling Windows compatibility again
Also fixes #491 as a nice bonus!

"Initialization, sizeof, and the assignment operator ignore the flexible array member."
Oops!

And added a test to check their behavior

Translate it to \\n regardless of the lexer mode

Attempt to grow it to the max size first.
Seriously, if this triggers, *how*

Also use a cleaner way, instead of hardcoding to capture

And add a test for it

Since the "skip ELSE blocks" variable is global, it used to get carried
