Subject: [dpdk-dev] [PATCH v1] eal: add ticket based reader writer lock

This patch implements a reader/writer ticket lock.
This lock type acts like rte_rwlock() but uses a ticket algorithm and are fair for
multiple writers and readers.
Writers have  priority over readers.  

The lock is ticket based to be fair. So writers should have no priority?

Read the articles referenced in the code.
The naming matches what the original MCS paper called it.
