Summary: Added support for switching SSLContexts based on the signature_algorithms
extension.
This diff does not currently include any logic for determining which certs use
SHA1 or not.

Some thoughts:
- This is a little scary since it defaults to SHA1 (assuming the client can't support
SHA256 if we don't see SHA256 specifically in the hello extension). We need to
be 100% sure that all clients that are going to reject SHA1 are sending this,
and that we identify it correctly.
- We should add logging to see when we think a client needs SHA1, when we
actually give SHA1, etc. I'm not sure what the best way to do this is with our
logging infrastructure.
- This is not setup to serve any SHA1 certs to SHA256 supporting clients.

Summary: Right now ThreadLocal & friends don't operate correctly when used as a
static variable (which is the idiomatic way to use them). The TLS id is
allocated in the static constructor so anybody who uses the ID prior to
first use would use an invalid ID. This makes ThreadLocal unusable for core
code such as per-thread reference counting.

This diff allocates the ID on first use. By making the invalid ID maxint we
avoid adding any extra branches in the fast path. We can then make the
constructor a constexpr meaning that initialization will happen prior to
any code running.

Summary: objdump was showing that the shiftXXX tables are being generated each
time this file is included. For example, HHVM has about 200 of each
of the 4 tables. Since each one is 512 bytes this is 400 KB. I'm not
quite sure why this was happening -- I'd think that the linker would
combine a constant table that was identical.

I think the best thing to do here is just to use extern template. This
way you there's only one copy of the table and you don't have to parse
all of this code in every file
