d3c9e07ff3 StringVector: add a way to get a string-number pair out of this ...
... without copying the token.

And use it in TileDesc::parse(), which is known to be a hot path.

784b7dc39d wsd: optimize StringVector
StringVector is heavily used for tokenization
and benefits from inlining of small functions.

Also, cat doesn't need to be slower than necessary.

a7d3efdd4e Introduce StringVector::equals()
Allows comparing tokens with C strings without a heap allocation. Do the
same when comparing two tokens from two different StringVectors.

And use it at all places where operator ==() has an argument, which is a
StringVector::operator []() result.

c99664b19c StringVector: fix build with gcc-4.9
Debian 8 has gcc-4.9, which emits -Werror in case a parameter and a
member function has the same name. Given that we also use -Werror
unconditionally, this breaks the build. Newer gcc/clang versions relaxed
this warning, so this was not a problem in those cases.

547f9ea731 Rework StringVector to have a single underlying string
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.)

b8bd1990aa Rework LOOLProtocol::tokenize() to return a StringVector object
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.
