global variables for sizes instead of calculating the same size over
and over again.

When setting environment variables in jobs we were tracking other job's
indexes and information, while the scope of the environment is totally
different for each job. The static variables have been moved to non static.

This fixes CUDA_VISIBLE_DEVICES indexing while running different jobs on
the same node.

Bug 4851

If block_map_size is zero (as seen on FreeBSD when not using HWLOC),
xmalloc(0) will return NULL. Writing to str[0] then is invalid.

Bug 4845.

Commit 943c4a13 introduced _register_oom_notifications()
which relies on eventfd() to subscribe to the memory.oom_control file.

As eventfd is unavailable on FreeBSD, disable this functionality
until some alternative implementation can be created.

Copy this definition from src/common/gres.c, along
with the necessary includes. (Note that these includes

Bug 4845.

Disable local PTY output processing when using 'srun --unbuffered'. This
prevents the PTY subsystem from inserting extraneous \r characters into
the output stream.

Bug 4849.

We've lived without it this long, just remove it.

And rename nonbg_entries to node_entries.
