f28e314b0d Make buf_pullup() expose the pulled-up data.
This lets us drop the testing-only function buf_get_first_chunk_data(),
and lets us implement proto_http and proto_socks without looking at
buf_t internals.

234c5015f1 Move protocol-specific functions out of buffers.c
This commit does not change the implementation of any function: it
only moves code and adds new includes as necessary.  Part of #23149.

ed4bc55450 Replace peek_buf_startswith() with a safe version
It's not okay to assume that the data in a buf_t is contiguous in
the first chunk.

Refactor the streaming compression code.
This patch refactors our streaming compression code to allow us to
extend it with non-zlib/non-gzip based compression schemas.

b923c4dc9f Code to disable memory sentinels for fuzzing
This feature makes it possible to turn off memory sentinels (like
those used for safety in buffers.c and memarea.c) when fuzzing, so
that we can catch bugs that they would otherwise prevent.

c4f2faf301 Don't atoi off the end of a buffer chunk.
Fixes bug 20894; bugfix on 0.2.0.16-alpha.

We already applied a workaround for this as 20834, so no need to
freak out (unless you didn't apply 20384 yet).

3cea86eb2f Add a one-word sentinel value of 0x0 at the end of each buf_t chunk
This helps protect against bugs where any part of a buf_t's memory
is passed to a function that expects a NUL-terminated input.

It also closes TROVE-2016-10-001 (aka bug 20384).

aae034d13e Write a bunch of module documentation.
This commit adds or improves the module-level documenation for:

  buffers.c circuitstats.c command.c connection_edge.c control.c
  cpuworker.c crypto_curve25519.c crypto_curve25519.h
  crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c
  dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c
  onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c
  protover.c protover.h reasons.c rephist.c replaycache.c
  routerlist.c routerparse.c routerset.c statefile.c status.c
  tor_main.c workqueue.c

In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it.  In a few cases, I've added TODO
notes about refactoring opportunities.

I've also renamed an argument, and fixed a few DOCDOC comments.

46ef4487d3 Remove generic_buffer_*() functions as needless.
These functions were there so that we could abstract the differences
between evbuffer and buf_t.  But with the bufferevent removal, this
no longer serves a purpose.

4f1a04ff9c Replace nearly all XXX0vv comments with smarter ones
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"

But we have a huge pile of such comments accumulated for a large
number of released versions!  Not cool.

So, here's what I tried to do:

  * 0.2.9 and 0.2.8 are retained, since those are not yet released.

  * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
    quite important!"

  * The others, after one-by-one examination, are downgraded to
    plain old XXX.  Which doesn't mean they aren't a problem -- just
    that they cannot possibly be a release-blocking problem.
