f494c27024 wsd: correct User-Agent usage in http headers
User-Agent is designed for client-side use only,
in http requests. For servers, the Server header
is designed to announce the server name and version.

This tries to normalize the use and documents
the proper intent and usage.

40b1aa1077 wsd: add member to Socket to flush safely
In many cases we write directly to the socket
outgoing buffer directly. The only way to flush
this buffer to the socket is to use send(),
which is artificial if we don't have any more
data to pass to send().

This makes it possible to safely call flush()
and, if there is buffered data, we flush it
to the socket.

da07625352 wsd: http: parse the http header only
Previously, we were parsing the Status Line
and the header, both together. This of course
doesn't work when we had removed the Status
Line already. This wasn't an issue in parsing
responses from servers, but doesn't work when
parsing requests from clients (i.e. in a server).

Also, it's simpler.

Tests extended accordingly.

b6314a6165 wsd: http: tolerate the absence of a reason phrase
Here we are more tolerant with regards to the
minimum Status Line length, since a Reason
Phrase is informative and might be omitted.

While technically it should be provided, per
the RFC, we shouldn't break when it's missing.

42a7607489 wsd: avoid static SocketPoll
The lifetime management of static objects
is extremely unpredictable and depends on
many variables outside of our control or
even reliable reproducibility.

Complex static objects that own threads
and other objects are doubly problematic
because of their dependency and/or
interaction with other objects.

Here we replace the static DelayPoll
instance with one we control its lifetime
in the LOOLWSD main body, such that it
is destroyed properly.

Specifically, DelayPoll's dtor  was
accessing Poco's Logging subsystem out of
order. That is, after Poco had been
destroyed.

Another advantage to this approach is that
we don't even create the DelayPoll at all
if we don't need it. The onus now is on
the user of DelayPoll to make sure they
create a Delay object with a long-enough
lifetime to encompase it use.

For completeness, here is the stacktrace:

    terminate called after throwing an instance of 'std::bad_alloc'
      what():  std::bad_alloc
