__saveds doesn't work in OFInit() yet - the entire point of OFInit() is
to set up things so that __saveds works. file: [47fd246f7b] check-in: [8cedd82180] user: js, branch: amiga-library, size: 13459 [annotate] [blame] [check-ins using] [diff]

All necessary changes to adjust for the changes made in trunk are
included in the merge commit. file: [fdc1473cd0] check-in: [3c88df0ce4] user: js, branch: amiga-library, size: 12824 [annotate] [blame] [check-ins using] [diff]

This is theoretical, as this is happening in Forbid() and hence nothing
should be able to change it, even after FreeMem(). However, some
debugging tools might break Forbid(), and this commit fixes those. file: [e46fd1fbb1] check-in: [82cba67e09] user: js, branch: amiga-library, size: 16298 [annotate] [blame] [check-ins using] [diff]

This is done by using functions that return a reference to the variable
and defining of_std{in,out,err} to a call into these functions. file: [00ace7a578] check-in: [9697334084] user: js, branch: amiga-library, size: 14816 [annotate] [blame] [check-ins using] [diff]

sscanf() is used internally by strtod(). file: [963ac93332] check-in: [e2fcdcb6bd] user: js, branch: amiga-library, size: 11904 [annotate] [blame] [check-ins using] [diff]

This way the runtime's linklib will use the ones passed to the ObjFW
.library. file: [5d844627f0] check-in: [45a8b2333d] user: js, branch: amiga-library, size: 11490 [annotate] [blame] [check-ins using] [diff]

This avoids needing to #undef std{in,out,err} and then providing a new
symbol. file: [1f4ef323c1] check-in: [514944f1ea] user: js, branch: amiga-library, size: 11030 [annotate] [blame] [check-ins using] [diff]

These are based on runtime/amiga-{library,glue,end}.m. file: [a7df8eae66] check-in: [f6ab72da6e] user: js, branch: amiga-library, size: 7607 [annotate] [blame] [check-ins using]
