install-deps.sh: exit on error if dependencies cannot be installed
Now that pre-installing pip dependencies is done at the end of the

the dependencies. Add explicit || exit 1 to commands that are to be

tests: fail make check if nproc is too low
When running tests in parallel with make -jX, the ulimit -u (number of
processor / thread per user) needs to be at least X * 1024. If not it
will fail in mysterious ways. Since there is no convenient way to figure
out the value of X ( see
http://blog.jgc.org/2015/03/gnu-make-insanity-finding-value-of-j.html
for a non trivial an entertaining solution) add a very conservative
check that assumes the user will run make -jX where X is nproc / 2.
It will be annoying for users who want to run make check, not use -j,
and have a low ulimit -u. But the error suggest a way to override this
with
make CHECK_ULIMIT=false check
This is a minor irritation compared to the puzzling behavior of make
check when ulimit is exceeded.

client: fix error handling in check_pool_perm
Previously, on an error such as a pool not existing,
the caller doing the check would error out, but
anyone waiting on waiting_for_pool_perm would
block indefinitely (symptom was that reads on a
file with a bogus layout would block forever).
Fix by triggering the wait list on errors and
clear the CHECKING state so that the other callers
also perform the check and find the error.
Additionally, don't return the RADOS error code
up to filesystem users, because it can be
misleading. For example, nonexistent pool is
ENOENT, but we shouldn't give ENOENT on IO
to a file which does exist, we should give EIO.
