Fix for corner case in the scratch allocator.
...
The scratch allocator could erroneously return a slice
overlapping previously allocated memory for allocation
requests that were smaller than the arena size, but larger
than the amount of free space left in the arena.
- fix the check in mem::scratch_alloc_bytes_non_zeroed
that wasn't routing the request to the backup allocator.
- added concrete reproduction test under tests/issues.

Make map_file_from_path use the open flags
...
map_file_from_path now passes the appropriate flags on to os.open
instead of always calling it with os.O_RDWR.
It will no longer try to open a file with write permissions if the user
didn't request write access to the file mapping (or vice-versa).

Fix buddy allocator assert
...
The last address of "data" is not "cast(uintptr)raw_data(data)+cast(uintptr)size" but
"cast(uintptr)raw_data(data)+cast(uintptr)(size-1)".
The original assert would fail when for example the allocation size requested and the buddy allocator allignment were both 64.

mem: Fix Buddy_Allocator size calculation to truly include alignment
...
This didn't take into account the size of the header plus the size of
the allocation itself by virtue of `align_forward_uint`; this could
result in no change if `size` was equal to `b.alignment` because the
number is aligned, and if `actual_size` and `size` ended up being equal,
no additional space would be requested.
This meant that a block would end up being allocated on top of its
buddy's head.
