tools/xenstore: set open file descriptor limit for xenstored
Add a configuration item for the maximum number of open file
descriptors xenstored should be allowed to have.
The default should be "unlimited" in order not to restrict xenstored
in the number of domains it can support, but unfortunately the kernel
is normally limiting the maximum value via /proc/sys/fs/nr_open [1],
[2]. So check that file to exist and if it does, limit the maximum
value to the one specified by /proc/sys/fs/nr_open.
As an aid for the admin configuring the value add a comment specifying
the common needs of xenstored for the different domain types.
