blk_alloc_i previously chose any resource group with a free block and
assumed that the bitmaps were already available in the rgrp_tree. This
patch allows us to allocate blocks in a resource group with a given
number of free blocks in order to plan ahead and reads in the bitmap
data on demand. It also removes some exit()s from blk_alloc_i.

In order to prepare for handling resource groups separately from buffer
heads in mkfs.gfs2, change gfs2_rgrp_out to copy rgrps to char buffers
instead of buffer heads. Copying to bh's is now done in
gfs2_rgrp_out_bh.

This folds much of the resource group allocation and writing into two
new functions so that we allocate memory for each entire header at once
and free it once we're done with it.
Testing on a 50TB volume with default options, this brings the peak heap
usage down from 3.03GB to 24MB while also reducing the run time
slightly due to fewer writes and allocations.
There are still memory efficiency gains to be made here, notably we
still use gfs2_compute_bitstructs which allocates bitmap buffers and an
array of bh pointers for each rgrp.

This makes the tool test script log command output to a file and only
remove the test file (now named testvol by default) on success so that
we can analyze it on failure.
Also adds some tests to create and check file systems with various
resource group sizes.

Previously the user-supplied options were tangled up with the calculated
file system parameters in the gfs2_sbd. This patch adds a mkfs_opts
structure to create a separation between the two and rearranges the code
to make that separation more apparent. It also adds some more tool tests
to be run with 'make check' and removes the now-unneeded orig_fssize
field from the gfs2_sbd definition.
