3e4c2fe712 Avoid error with old Bison versions 
`api.token.raw` is only defined starting with Bison 3.5
Since it's not essential, define it on the command-line iff the Bison
version is sufficient.

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.

4f842a1248 Create specialized symbol finder functions 
The old "find symbol with auto scope" function is now three:
- One finds the exact name passed to it, skipping any checks
  This is useful e.g. if such checks were already performed.
- One checks that the name is not scoped, and calls the first.
  This is useful for names that cannot be scoped, such as checking for EQUS.
  Doing this instead of the third should improve performance somehwat, since
  this specific case is hit by the lexer each time an identifier is read.
- The last one checks if the name should be expanded (`.loc` → `Glob.loc`),
  and that the local part is not scoped. This is essentially the old function.

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.
