Currently we're unable to online resize very small (smaller than 32 MB)
file systems with 1k block size because there is not enough space in the
journal to put all the reserved gdt blocks.
I tried to find solution in kernel which does not require to reserve
journal credits for all the gdt blocks, but it looks like we have to
have them all in journal to make sure that we atomically either change
them all, or none.
So it leaves us with fixing the root cause which is the fact that mke2fs
is setup by default so that it creates so many gdt blocks that it can't
fit into the journal transaction.
Fix it by limiting the default number of reserved gdt blocks in the
specific case of 1k bs and fs size < 32M. Note that it's still possible
to create such file system by specifying non-default options so I've
added mke2fs message that would warn users that would try to create such
file system, but will still allow them to do so.
We still need to address the kernel problem where such file system would
generate scary kernel warning, but that's for a separate patch.
Also fix output of some tests, because this change slightly alters the
file system layout (specifically number of free blocks and number of
reserved gdt blocks) on very small file systems.
