booster: Add new booster-specific fd-table
The reason we need a booster specific fd-table is because the libglusterfs fd-table has come to a point where it is optimized for libglusterfs-style of fd allocations. This conflicts with the way booster requires fds to be allocated so this commit brings in a re-based version of a booster-specific fd-table written by Raghu. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
