LU-443 LNet: Only squawk when md->start is NULL on non-zero length

Only squawk when md->start is NULL on non-zero length.
The md->start == NULL check prevents anyone from creating a ME/MD
with no buffer. These are used as backstop buffers to generate events
when traffic has exceeded the local buffer space.

larger than 16TB in size.

Reduce the number of inodes created on larger OST filesystems, since

Skip zeroing the journal at format time.  It will be overwritten

LU-296 Add missing code from auster/yaml port to b1_8

Code related to defining and creating the $TF_FAIL file was missed in
the port of auster and yaml to b1_8. This patch adds the missing
code. Namely:

- Define TF_FAIL in acceptance-small.sh
- add 'touch $TF_FAIL' to the test-framework.sh ERR signal trap

Additionally, the file test for $TF_FAIL variable should be quoted in
acceptance-small.sh and auster.sh. Otherwise, if this variable is not
defined, bash will spit out something like

acceptance-small.sh: line 123: [: too many arguments

Bash variables should generally be quoted whenever they are referenced.
