8e32e1abbc Generate a dictionary of OIDs for fuzzers
It turns out that (some?) fuzzers can read a dictionary of OIDs,
so we generate one as part of the usual 'make update'.

Fixes #4615

9f08a1c63e Install custom RAND_METHOD for fuzzing
Instead of setting a "magic" global variable to force RAND to keep
consistent state and always generate the same bytestream, have
the fuzzing code install its own RAND_METHOD that does this.  For
BN_RAND_DEBUG, we just don't do it; that debugging was about mucking
with BN's internal representation, not requiring predictable rand
bytes.

b12ae4a912 fuzz/{client,server}.c: omit _time64 "overload method".
Approach was opportunistic in Windows context from its inception
and on top of that it was proven to be error-prone at link stage.
Correct answer is to introduce library-specific time function that
we can control in platform-neutral manner.  Meanwhile we just let
be attempts to override time on Windows.

ff54cd9beb Optionally check for early data
This adds a way to use the last byte of the buffer to change the
behavior of the server. The last byte is used so that the existing
corpus can be reused either without changing it, or just adding a single
byte, and that it can still be used by other projects.

8a585601fe Fix out-of-memory condition in conf
conf has the ability to expand variables in config files. Repeatedly doing
this can lead to an exponential increase in the amount of memory required.
This places a limit on the length of a value that can result from an
expansion.

Credit to OSS-Fuzz for finding this problem.

d69d8f904c Make the fuzzers more reproducible
We want to be in the same global state each time we come in
FuzzerTestOneInput(). There are various reasons why we might not be that
include:
- Initialization that happens on first use. This is mostly the
  RUN_ONCE() things, or loading of error strings.
- Results that get cached. For instance a stack that is sorted, RSA
  blinding that has been set up, ...

So I try to trigger as much as possible in FuzzerInitialize(), and for
things I didn't find out how to trigger this it needs to happen in
FuzzerTestOneInput().
