Subject: [PATCH] fix(mksquashfs): use st_atimespec on macOS
Darwin struct stat does not expose st_atim. Use st_atimespec on macOS while keeping existing behavior on other platforms.

Subject: [PATCH] mksquashfs: don't create duplicate virtual -> real disk
mappings
This bug is caused by commit 472588dc40292fa3d047369f1e758016a6b26e70,
but it is exposed by commit 078529915caab11e85299aac1304671151d507a3.
The first commit adds a virtual -> real disk mapping in cases where a
multi-block file contains all sparse blocks. In this case no data
block has been written for this file, and it may mean no virtual -> real
disk mapping will exist otherwise.
However, a side effect of this is two duplicate virtual -> real disk
mappings may be created, with different values.
Now previously before commit 078529915caab11e85299aac1304671151d507a3,
Mksquashfs waited for all outstanding data blocks to be processed by the
orderer thread before creating the metadata. At this point all the
duplicate virtual -> real disk mappings will exist, and the lookup
routine will return the last one created - which happens to be the
correct one.
After commit 078529915caab11e85299aac1304671151d507a3, Mksquashfs no
longer waits for all outstanding data blocks to be processed by the
orderer thread, which means when the lookup takes place in metadata
creation, there may exist only the first wrong duplicate, which will be
returned. Obviously there may exist both duplicate values in which case
the correct one will be returned. In other words this is a race
condition, and it is highly dependent on hardware and input data
whether it triggers.
The fix is to increment the virtual disk position after creating a
mapping when a multi-block file contains all sparse blocks. This
obviously prevents duplicate mappings from being created.
