Subject: [PATCH] Thrift-1997:Add accept backlog configuration method to
 TServerSocket Client: cpp Patch: Randy Abernethy

TServerSocket hard codes the accept backlog to 1024. This patch adds a setAcceptBacklog() method which can be used to change the backlog size (must be called prior to listen()).
