size_t in C and in C++ are not necessarily the same
type. The C++ size_t is in the std namespace. Since
we do include many C headers, and indeed some C++
runtime headers do define size_t for backwards
compatibility, it's easy to mix and match the two
types.
Also, 'using std::size_t;' isn't a great practice,
so removed.
This is not exhaustive, just some low-hanging cases.

This is meant to reduce lots of small allocations and instead have
pointers into the single string for the various tokens instead.
This has a few requirements, though:
1) It's no longer OK to modify the tokens, changing their length would
invalidate the start/length of other tokens. Rework
DocumentBroker::load() to avoid such mutation.
2) The iterators no longer expose zero-terminated strings, so
Poco::cat() doesn't work anymore: add an own cat() instead and use that
in e.g. ChildSession. The own cat() has the benefit that it won't read
past the end of the array if the begin index is out of bounds to add
more safety.
(This nicely works towards killing Poco usage in general.)
3) If zero-terminated strings for all individual tokens is needed, a
copy has to be made, as done in spawnProcess().
(For all of these requirements, the build fails if there are problems.)

The bulk of this commit just changes std::vector<std::string> to
StringVector when we deal with tokens from a websocket message.
The less boring part of it is the new StringVector class, which is a
wrapper around std::vector<std::string>, and provides the same API,
except that operator[] returns a string, not a string&, and this allows
returning an empty string in case that prevents reading past the end of
the underlying array.
This means in case client code forgets to check size() before invoking
operator[], we don't crash. (See the ~3 previous commits which fixed
such crashes.)
Later the ctor could be changed to take a single underlying string to
avoid lots of tiny allocations, that's not yet done in this commit.

The server tells the client the hash of each tile it sends (calculated
from the contents of the tile, not its PNG encoding). When the client
asks for a tile to be refreshed, it tells the server what the hash of
the existing tile is. If the server notices that the tile contents
hasn't actually changed, it doesn't PNG encode it and doesn't send it
to the client.
The intent is that this will reduce load on the server and also avoid
unnecessary tile traffic.
