dddff0f450 Cannot start a new section that's already on the stack 
This is only relevant for FRAGMENT or UNION sections, since
normal ones would fail with "Section already defined previously".

b3c0db218d Remove "EOF-newline" lexer hack 
In preparation for an upcoming change
Makes for nicer error messages, complaining about EOF instead of newlines
The hack had to be kept for the lexer raw mode to avoid a bug;
see the relevant code comment for more info.

93d83e17dc Don't override bison's internal 'yytnamerr' function 
This is not used in all bison versions, which causes a
"defined but not used" warning for the 'rgbasm_yytnamerr'
replacement, treated as an error by 'make develop'.

57b734a7df Reinstate RL into the _RS family 
Removal of colon-less labels lifted the grammar ambiguity that
prevented `RL` from being usable as a variable declarator.
Thus, reinstate its functionality.

462fd7539c Prohibit nested macros 
After discussion (starting there:
https://github.com/gbdev/rgbds/pull/594#issuecomment-706437458
), it was decided that plain nested macros should not be
allowed.
Since #590 is fixed, EQUS can be used as a workaround;
multiline strings (#589) will make that easier on the
user when implemented.
Fixes #588, supersedes and closes #594.
Additionally, closes #388.

b07aa00d5c Don't overwrite symbol when it's not allowed 
When a user tried to overwrite a builtin symbol, it would change its
type despite the error, making the second try succeed. This is
problematic, as the location of a builtin symbol cannot be updated.
