This puts CONFIG_PROC_FS defines around the proc init/exit functions
and also avoids compiling proc.c if procfs is not supported.
Also make SCTP_DBG_OBJCNT depend on procfs.

The crc32c library used an identical table and algorithm
as SCTP.  Switch to using the library instead of carrying
our own table.  Using crypto layer proved to have too
much overhead compared to using the library directly.

SCTP-AUTH requires selection of CRYPTO, HMAC and SHA1 since
SHA1 is a MUST requirement for AUTH.  We also support SHA256,
but that's optional, so fix the code to treat it as such.

Use menuconfigs instead of menus, so the whole menu can be disabled at
once instead of going through all options.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
