blkdebug: Avoid '.' in enum values

Our qapi conventions document that '.' should only be used in
the prefix of downstream names. BlkdebugEvent was a lone
exception to this. Changing this is not backwards compatible
to the 'blockdev-add' QMP command; however, that command is
not yet fully stable. It can also be argued that the testsuite
is the biggest user of blkdebug, and that any other user can
be taught to deal with the change by paying attention to
introspection results.

Done with:

$ for str in \
l1_grow.{alloc,write,activate}_table \
l2_alloc.{cow_read,write} \
refblock_alloc.{hookup,write,write_blocks,write_table,switch_table} \
pwritev_rmw.{head,after_head,tail,after_tail}; do
str1=$(echo "$str" | sed 's/\./\\./')
str2=$(echo "$str" | sed 's/\./_/')
git grep -l "$str1" | xargs -r sed -i "s/$str1/$str2/g"
done

followed by a manual touchup to test 77 to keep the test working.

iotests: Prepare for refcount_bits option

Some tests do not work well with certain refcount widths (i.e. you
cannot create internal snapshots with refcount_bits=1), so make those
widths unsupported.

Furthermore, add another filter to _filter_img_create in common.filter
which filters out the refcount_bits value.

This is necessary for test 079, which does actually work with any
refcount width, but invoking qemu-img directly leads to the
refcount_bits value being visible in the output; use _make_test_img
instead which will filter it out.
