Miklos Vajna e4298ccf31 fuuzer, httpresponse: clear state before each run
The max input size is 16384, so in case the input is saved after each
run, then this can allocate ~300MB of memory. This is considerable
amount, given that the upper limit of the fuzzer process is 2GB.

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/
----

- HttpEcho:

----
./httpecho_fuzzer -max_len=16384 fuzzer/httpecho-data/
OR, better:
./fuzzer/httpecho-fuzz.sh
----
