Revert "TS-2780: Core dump in SpdyRequest::clear() in production testing of SPDY"

This reverts commit c9d4433531767c9b5f6db42b488af4552bc5c4a9.
TS-2780: Core dump in SpdyRequest::clear() in production testing of SPDY
updated changes to include TS-2780
TS-2649: use certificate chain loading everywhere

Use SSL_CTX_use_certificate_chain_file() everywhere we load a SSL
certificate. This lets the operator use a certificate chain in a
single file for both the SSL client and server.
TS-2931: plugin metrics fail after a crash

If a plugin uses TSStatFindName followed by TSStatCreate, TSStatFindName
can return 0 for all the metric IDs after a traffic_server crash.

This will happen every time with the following conditions:
  1. traffic_manager has pulled the stat records from traffic_server
  2. traffic_server crashes

When traffic_server comes back up, it pulls the records from
traffic_manager. traffic_manager sends the records including the
rsb_id field. However, RecForceInsert() does not copy the rsb_id
field from the message to the actual record. Subsequent stat lookups
succeed because the stat is registered, but always receive a rsb_id
of 0.

The fix is to ensure that we copy the rsb_id field so that stat
lookups succeed.
TS-2932: specify the build number at build time

Add a --with-build-number configuration option so that this can be
published in proxy.node.version.manager.build_number and
proxy.process.version.server.build_number.
Fix error message spelling
TS-2904: add Via header decoder option to traffic_line

TS-2930: missing hostname in ts.client_request.get_url() in lua plugin
TS-2935: clean up semaphore platform code

Darwin does not implement anonymous semaphores, but that's no reason
to litter #ifdefs all over the place. Clean up the ink semaphore
interface to provide a consistent anonymous semaphore interface.

Remove the Ethread semaphore code because it is never used, and
it's not clear that it could be used.
TS-1475 Remove unused ink_segv
Update the CI builds with the latest changes that got left on server
