9d5bc1a935 Move zlib compression code into its own module.
This patch refactors the `torgzip` module to allow us to extend a common
compression API to support multiple compression backends.

Additionally we move the gzip/zlib code into its own module under the
name `compress_zlib`.

c2947dbb86 Move config_line_t functions from confparse.c into common.
I'm doing this to storagedir to used config_line_t.

ee253e392a Define a "storagedir" abstraction to hold numerous similar files
We could use one of these for holding "junk" descriptors and
unparseable things -- but we'll _need_ it for having cached
consensuses and diffs between them.

aa971c5924 Move our "what time is it now" compat functions into a new module
I'm not moving our "format and parse the time" functions, since
those have been pretty volatile over the last couple of years.

6d6c8287d5 Include __mulodi4 in libor_ctime when it fixes clang -m32 -ftrapv
We use a pretty specific pair of autoconf tests here to make sure
that we only add this code when:
   a) a 64-bit signed multiply fails to link,
 AND
   b) the same 64-bit signed multiply DOES link correctly when
      __mulodi4 is defined.

Closes ticket 19079.

445e05a015 Fix inconsistent tab/space mixing in include.am files.
This is a whitespace only, cosmetic fix.

There is still some inconsistency between lists, but less
inconsistency inside individual lists.

ce854a8d22 Add -ftrapv to gcc-hardening ... mostly!
We know there are overflows in curve25519-donna-c32, so we'll have
to have that one be fwrapv.

Only apply the asan, ubsan, and trapv options to the code that does
not need to run in constant time.  Those options introduce branches
to the code they instrument.

(These introduced branches should never actually be taken, so it
might _still_ be constant time after all, but branch predictors are
complicated enough that I'm not really confident here. Let's aim for
safety.)

Closes 17983.

80a6c8caa3 Basic work on a publish/subscribe abstraction
The goal here is to provide a way to decouple pieces of the code
that want to learn "when something happens" from those that realize
that it has happened.

The implementation here consists of a generic backend, plus a set of
macros to define and implement a set of type-safe frontends.

347fe449fe Move formatting functions around.
The base64 and base32 functions used to be in crypto.c;
crypto_format.h had no header; some general-purpose functions were in
crypto_curve25519.c.

This patch makes a {crypto,util}_format.[ch], and puts more functions
there.  Small modules are beautiful!

0f3eeca9b8 Integrate ed25519-donna (Not yet used).
Integrate ed25519-donna into the build process, and provide an
interface that matches the `ref10` code.  Apart from the blinding and
Curve25519 key conversion, this functions as a drop-in replacement for
ref10 (verified by modifying crypto_ed25519.c).

Tests pass, and the benchmarks claim it is quite a bit faster, however
actually using the code requires additional integration work.

c66dd17980 Drop support for --digests

Remove src/or/or_sha1.i and src/common/common_sha1.i on `make clean` and remove
the temporary micro-revision file when its no longer needed.

Additional changes;
- show a message when generating the micro-revision file.
- add the temporary micro revision file to the list of files to be removed on
  `make clean` just in case.
- fix indentation of the make rule to improve readability.

6f331645c7 Remove mempools and buf freelists
They have been off-by-default since 0.2.5 and nobody has complained. :)

Also remove the buf_shrink() function, which hasn't done anything
since we first stopped using contiguous memory to store buffers.

c2f0d52b7f Split threading-related code out of compat.c
Also, re-enable the #if'd out condition-variable code.

Work queues are going to make us hack on all of this stuff a bit more
closely, so it might not be a terrible idea to make it easier to hack.

909aa51b3f Remove configure option to disable curve25519
By now, support in the network is widespread and it's time to require
more modern crypto on all Tor instances, whether they're clients or
servers. By doing this early in 0.2.6, we can be sure that at some point
all clients will have reasonable support.

e84e1c9745 More generic passphrase hashing code, including scrypt support
Uses libscrypt when found; otherwise, we don't have scrypt and we
only support openpgp rfc2440 s2k hashing, or pbkdf2.

Includes documentation and unit tests; coverage around 95%. Remaining
uncovered code is sanity-checks that shouldn't be reachable fwict.
