Miklos Vajna 4433e03492 client session fuzzer: try harder to empty SocketPoll::_newCallbacks on shutdown
The DocumentBroker dtor adds a callback:

	#0  SocketPoll::addCallback(std::function<void ()> const&) (this=0x377dce0 <Admin::instance()::admin>, fn=...) at ./net/Socket.hpp:773
	#1  0x0000000000947db5 in Admin::rmDoc (this=<optimized out>, docKey=...) at wsd/Admin.cpp:544
	#2  0x0000000000bb8192 in DocumentBroker::~DocumentBroker (this=0x61900000e690) at wsd/DocumentBroker.cpp:579

So even if the fuzzer called Admin::instance().poll() on shutdown, there
was one more callback inserted to the list later, leading to OOM in the
long run.

README

These fuzzers are meant to be built and executed inside lode.git's sanitizers
environment (currently enables both asan and ubsan).

online.git can be built the usual way, just the additional `--enable-fuzzers`
flag is needed to build the fuzzers. It is useful to do this in a separate
build tree, since the fuzzers config doesn't produce a `coolwsd` binary.

Run the fuzzers like this:

- Admin:

----
./admin_fuzzer -max_len=16384 fuzzer/admin-data/
----

- ClientSession:

----
./clientsession_fuzzer -max_len=16384 fuzzer/data/
----

- HttpResponse:

----
./httpresponse_fuzzer -max_len=16384 fuzzer/httpresponse-data/
----
