build: configure: Silence pkg-config check for libnetfilter_conntrack
Redirect stderr output of pkg-config to config.log in order to not spam the configure output with pkg-config errors. Instead, use the same pkg-config commands as for the other library checks to get libnetfilter_conntrack cflags. Additionally, use pkg-config to the the linker flags as well. Fixes: 19991f90 ("build: Handle libnetfilter-conntrack with pkg-config") Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

d_to_signal_on_read()
Commit a389fcfd2cb5 ("Drivers: hv: vmbus: Fix signaling logic in hv_need_to_signal_on_read()") added the proper mb(), but removed the test "prev_write_sz < pending_sz" when making the signal decision. As a result, the guest can signal the host unnecessarily, and then the host can throttle the guest because the host thinks the guest is buggy or malicious; finally the user running stress test can perceive intermittent freeze of the guest. This patch brings back the test, and properly handles the in-place consumption APIs used by NetVSC (see get_next_pkt_raw(), put_pkt_raw() and commit_rd_index()).
