Make fatal signals cause an exit more promptly in special cases.
The fatal-signal library notices and records fatal signals (e.g. SIGTERM)
and terminates the process on the next trip through poll_block(). But
some special utilities do not always invoke poll_block() promptly, e.g.
"ovs-ofctl monitor" does not call poll_block() as long as OpenFlow messages
are available. But these special cases seem like they are all likely to
call into functions that themselves block (those with "_block" in their
names). So make a new rule that such functions should always call
fatal_signal_run(), either directly or through poll_block(). This commit
implements and documents that rule.

Until now the names of the external_ids keys used for Bridge records have
implied that they are specific to XenServer, because they begin with "xs-".
They are more generic in intent, however, so this commit removes the "xs-"
prefix and explains them more generically.
This finishes the renaming process started in commit
c0f9490 "vswitchd:
Make names of Interface external_ids generic."

stream-ssl: Make no-op reconfiguration cheap.
Until now, the stream_ssl functions for configuring private keys,
certificates, and CA certificates have always called into OpenSSL to read
a file. This commit instead makes them do that only if the file name
changed (or it has been 60 seconds since we last tried, in case someone
installed the file behind our backs).
This allows us to factor some code out of vswitchd. In an upcoming commit
we will want to do essentially the same thing from ovsdb-server, so this
avoid code redundancy.

stream-ssl: Permit race in bootstrapping CA certificate.
If two processes were both configured to bootstrap the CA certificate, then
one of them would succeed in writing it to a file and use it, and the other
one would fail to use it because the file was created behind its back.
This commit fixes the problem by making the bootstrap code accept a CA
certificate file that exists at the time that bootstrapping tries to create
it.

Also, compact the database online if the "ovsdb-server/compact" command is
